31 t-TEST FOR DEPENDENT
GROUPS
STATISTICAL TECHNIQUE IN REVIEW

The t-test for dependent groups is a parametric analysis technique used to determine statistical
differences between two related samples or groups. Groups are dependent or related because they
were matched as part of the design to ensure similarities between the two groups and thus reduce
the effect of extraneous variables. For example, two groups might be matched on gender so an
equal number of males and females are in each group, thus reducing the extraneous effect of gender on the study results. The researcher’s decision to match groups is determined by the study being conducted and is detailed in the study design. In previous research, groups have most commonly been matched for age, gender, ethnicity, diagnoses, and status of illness. Matching the groups strengthens the study design by reducing the effect of extraneous variables controlled by matching. Groups are also dependent when scores used in the analysis are obtained from the same subjects under different conditions, such as pretest and posttest study design. In this type of design, a single group of subjects is exposed to pretest, treatment, and posttest. Subjects are referred to as serving as their own control during the pretest that is then compared with the posttest scores following the treatment. This is a weak quasi-experimental design since it is difficult to determine the effects of a treatment without comparison to a separate control group. The assumptions for the t-test for dependent groups are:
1.
The distribution of scores is normal or approximately normally distributed.
2. The dependent variable(s) is (are) measured at interval or ratio levels.
3.
The groups examined for differences are dependent based on matching or subjects serving as
their own control.
4. The differences between the paired scores are independent (Burns & Grove, 2005).

Introduction
Kim, Junes, and Song (2003) conducted a quasi-experimental study with a one group pretest-posttest
design. “A convenient sample of 21 elderly women was recruited from a home for elderly people.” (Kim et al., 2000, p. 376). The purpose of the study was to determine the health benefits of a 3-month health-promotion program for institutionalized elderly women on cardiovascular risk factors,
health behaviors, and life satisfaction. These researchers found the following positive effects from the
program: reductions in total risk score, improved health behaviors, and improved life satisfaction.
However, Kim et al. (2003) noted a decrease in these positive effects 3 months after the completion
of the health-promotion program.

Relevant Study Results
A total of 25 women were enrolled in the health-promotion program and 21 subjects completed the
program with three sets of outcome assessments at pretest, 3 months, and 6 months. The mean age
of the subjects was 77 years, and 90% of them had been diagnosed with one or more chronic
diseases. The significance level of the study was set at a= 0.05. The results from the study are
presented in the two tables that follow. Table 2 describes the health-promotion program’s effects
on cardiovascular risk factors, and Table 3 describes the effects on health behaviors. The third
dependent variable of this study was life satisfaction, which was significantly improved from
pretest to the end of the health-promotion program at 3 months and at 6 months follow-up.

7.
What is the smallest, significant t ratio listed in Table 3? Provide a rationale for your answer.
8. Why do you think that the smaller t ratios are not statistically significant?
9. How would you describe the result t = –1.45 in this study?

ANSWERS TO STUDY QUESTIONS
1.
This study was conducted using a one group pretest-posttest design in which the subjects serve as their own
control. The subjects’ outcomes at 3 and 6 months were compared with their pretest values. The single
sample pretest-posttest design indicates that the groups were dependent or related. In Tables 2 and 3 the
t-tests are identified as paired t-tests, which are conducted on dependent groups.
2. t = –3.93 (Exercise) is the largest t ratio at 6 months, as listed in Table 3.
3. t = –0.80 (BMI) represents the smallest t-ratio at 6 months, as listed in Table 2.
4.
t = –0.93 indicates the difference in Diet behavior from pretest to 3 months. This t-ratio does not have an
asterisk (*) next to it in Table 3; therefore, it is not statistically significant. The asterisk directs the reader to
the footnotes at the bottom of the table where the asterisk is said to represent p < 0.05, the least stringent
acceptable value for statistical significance.
5.
t = 3.44* (3 months) and t = –0.80 (6 months). At 3 months, the difference in BMI (body mass index) from
pretest was statistically significant with t = 3.44*, p < 0.05. At 6 months, the difference in BMI from pretest
was no longer statistically significant with t = –0.80. These results indicate that although initially the BMI
decreased significantly from the pretest (mean = 22.7) to 3 months (mean = 22.1), the BMI actually increased
at 6 months (mean = 22.9). Thus, the health-promotion intervention did not have a positive long-term
effect on the subject’s BMI, since the subjects demonstrated an increase in BMI versus a decrease.
6.
The t-test for dependent groups is conducted to determine statistical differences between two related or
dependent groups. The t-test can be used to determine differences between two dependent groups following
a treatment and also for comparing and contrasting two groups for a selected variable. Paired t-test is
another name for the t-test for dependent groups.
7.
t = –3.02*, p< 0.05 is the smallest significant t ratio listed in Table 3. The –3.02 is the smallest t ratio with
an *, indicating that Total health behavior was statistically significant from pretest to 3 months in this
study at p < 0.05.
8.
The small t ratios indicate small relative differences between the two groups that are usually not statistically
significantly different, especially in small sample studies. The larger the calculated t ratios, the smaller the
observed p values and the more likely one will reject the null hypothesis, since the groups are significantly
different.
9.
The result t = –1.45 indicates that there is no statistically significant difference in Smoking behavior
from pretest to 3 months in this sample. Thus, the null hypothesis would be accepted, which states the health-
promotion intervention did not have an effect on Smoking behavior.

Comparing and Contrasting Two Poems by the Same Author

Comparing and Contrasting Two Poems by the Same Author

As Mary Oliver writes in A Poetry Handbook, “A poem requires a design—a sense of orderliness… Even if the poem is a description of unalleviated chaos, it is a gathering of words and phrases and patterns that have been considered, weighed, and selected” (58). This assignment asks you to analyze the specific choices a poet makes in the design of his of her poems which impact the reader’s experience of the content and meaning of the work.

Goals: Our third essay directs further study toward the ways that an author uses formal elements to construct—and convey meaning within—his or her writing. We’ll practice the comparison and contrast method of organization and work on tightening your essays by looking at the need for a balance between having a strong claim (thesis) and offering strong evidence. We’ll also continue to do exploratory writing using the toolbox of techniques like “Notice and Focus” as suggested in Writing Analytically.

Reading: You’ll be writing about two poems by the same poet: choose one set of poems linked in the Essay 3 folder in Course Material.

Please also read the following sections in Writing Analytically: the selection about “Comparison/Contrast” (156-158) as well as the “Guidelines” on pages 159-160 and the sample assignment #2 on pages 160-161 in Chapter 7, and all of Chapter 12 on “Recognizing and Fixing Weak Thesis Statements” (255-265).

In addition, please read the handouts on analyzing poetry and comparing and contrasting linked in the Essay 3 folder.:

Folder Essay:
Poems to Analyze
Please read all 3 sets of poems below. You will chose 1 set of poems (2 poems by the same poet) to analyze for your Essay 3.

1.Cornelius Eady, &quot;Money Won’t Change It&quot; (http://www.poetryfoundation.org/poem/178995) and &quot;A Small Moment&quot; (http://www.poetryfoundation.org/poem/182745)

Assignment: Analyze the set of two poems by one of the three poets linked in the Essay 3 folder by comparing and contrasting the poems in order to make an overall claim in which you point out the significance of reading these two poems together in terms of gaining a larger understanding about the particular poet’s work. There are two main kinds of ideas to think about in coming up with your thesis…

• Consider how the two poems are complementary. Does reading the two poems together give the reader a fuller view of a theme that seems to be important in the poet’s work? Do both poems use specific elements of poetry in a way that’s important for us to study, and why is this similarity important?

• Consider how the poems reveal difference or variety in terms of the thematic content or formal/technical choices this poet utilizes. Why do you think the poet makes different choices in the two poems, and why are they important?

As our textbook suggests, you can offer some especially complex analysis if you can combine these two kinds of ideas to find similarity within difference or difference within similarity. For example, maybe the two poems are about totally different subjects, but you find that the speaker in each poem sounds the same and that both poems use metaphor to clarify ideas for the reader. Or maybe you find that both poems explore a similar theme, but the poet emphasizes different formal elements in each poem to convey that theme.

To support your thesis, you’ll need to do a close reading of each poem so that you can analyze the relationship between form and content: your evidence will be based on the specific details/examples you can point to within the poem that back up your main idea. How do some of the formal elements—concrete imagery, figurative language, number and length of stanzas, line breaks, meter/rhythm, tone, voice/speaker, etc—reinforce the literal content of each poem and what you interpret to be each poem’s meaning? Where is the poet making similar choices in both poems (compare), and where is the poet making different choices in the two poems (contrast)? You’ll be answering these kinds of questions in your paper, giving your reader a thoughtful, well-reasoned perspective on the importance of reading these two poems together.

You don’t have to discuss all of the questions above; try to choose what seems most important to you. In discussing the two poems, you need to come up with a dominant idea; this means that it’s not enough to simply list ideas (similarities and differences) about the poems: you have to make a larger point. This “larger point” is expressed in your thesis statement, in which you’ll make a specific claim to show how the important details you notice regarding the form and content of both poems help to prove the larger point you’re making about what the reader can learn and/or better understand from comparing and contrasting these poems in the way(s) you explain in your paper.

Generating Ideas: It might help to begin with your own perspective as a reader. Reflect on your own responses as you read the poems. Try reading each of your two poems several times, and make notes with each reading: first, read to understand the literal events of each poem (what’s happening in the poem); second, read to interpret what you think each poem means (what ideas do you take from the poem, and what makes the poem intellectually and emotionally engaging for you?); third, read carefully to assess the use of formal elements in the poem and think about how and why the poet has made these specific formal choices in light of your ideas regarding the poem’s content and meaning. When you think about these poems together, what important similarities and differences do you notice?

Specs: Your essay should have 3 pages double-spaced pages in length. As usual, this assignment calls for a thesis-centered essay in which your original title signals your thesis, your introduction clearly leads into and states your thesis, and your topic sentences indicate how each of your body paragraphs will present a unified idea in support of your thesis. You’ll need to provide ample evidence from the text (at least 3 citations, but probably more) along with your own reasoning to create a coherent and logical flow of ideas. Please cite your sources according to MLA format, with a Works Cited list as well as in-text citations.

There are a couple of different options for structuring a comparison/contrast paper.

In-Text Citations (MLA) for Poems: Type quotations of three lines or less within the text and insert slashes between the lines to show the line breaks. Instead of citing page numbers, give the line numbers in parentheses, immediately after the closing quotation marks and before the closing punctuation of your sentence. It is customary to say “line” or “lines” before the line number(s) so that the reader knows these are not page numbers. Example:

Langston Hughes asks a series of questions about the “dream deferred” (line 1) in “Harlem,” including: “Does it dry up / like a raisin in the sun?” (lines 2-3).

Quotations of four lines or more should appear as “block” quotes and be indented ten spaces from the rest of the text. No quotation marks are used for block quotes, and line numbers should be placed immediately following the closing punctuation of the last line in the quote. Example:

In “Theme for English B,” Hughes takes the reader from the speaker’s school to his home:

The steps from the hill lead down into Harlem
through a park, then I cross St. Nicholas,
Eighth Avenue, Seventh, and I come to the Y,
the Harlem Branch Y, where I take the elevator. (lines 11-14)

A Note on Poetry: Even in a poem which seems to be based on events in a poet’s life—a poem in which the “I” of the first-person speaker (or voice) in the poem might easily be equated with the “I” of the poet—the choice to use the “I” is a deliberate artistic choice like any other. The poet Joan Aleshire writes that the successful poem “allows for the expression” of highly personal content, but achieves some measure of artistic distance through the poet’s care to “[impose] a degree of objectivity on the material by formal—but not always traditional—devices.” In other words, just because a poet uses “I” in a poem doesn’t mean we can assume the poem is a true account about the poet’s own life.

Exploring Innovation in Action: The Dimming of the Light Bulb

Exploring Innovation in Action: The Dimming of the Light Bulb

In the beginning….
God said let there be light. And for a long time this came from a rather primitive but surprisingly effective method – the oil lamp. From the early days of putting simple wicks into congealed animal fats, through candles to more sophisticated oil lamps, people have been using this form of illumination. Archaeologists tell us this goes back at least 40,000 years so there has been plenty of scope for innovation to improve the basic idea! Certainly by the time of the Romans, domestic illumination – albeit with candles – was a well-developed feature of civilised society.
Not a lot changed until the late eighteenth century when the expansion of the mining industry led to experiments with uses for coal gas – one of which was as an alternative source of illumination. One of the pioneers of research in the coal industry – Humphrey Davy – invented the carbon arc lamp and ushered in a new era of safety within the mines, but also opened the door to alternative forms of domestic illumination and the era of gas lighting began.
But it was not until the middle of the following century that researchers began to explore the possibilities of using a new power source and some new physical effects. Experiments by Joseph Swann in England and Moses Farmer in the USA (amongst others) led to the development of a device in which a tiny metal filament enclosed within a glass envelope was heated to incandescence by an electric current. This was the first electric light bulb – and it still bears more than a passing resemblance to the product found hanging from millions of ceilings all around the world.
By 1879 it became clear that there was significant commercial potential in such lighting – not just for domestic use. Two events occurred during that year which were to have far-reaching effects on the emergence of a new industry. The first was that the city of Cleveland – although using a different lamp technology (carbon arc) – introduced the first public street lighting. And the second was that patents were registered for the incandescent filament light bulb by Joseph Swann in England and one Thomas Edison in the USA.
Needless to say the firms involved in gas supply and distribution and the gas lighting industry were not taking the threat from electric light lying down and they responded with a series of improvement innovations which helped retain gas lighting’s popularity for much of the late nineteenth century. Much of what happened over the next 30 years is a good example of what is sometimes called the ‘sailing ship effect’. That is, just as in the shipping world the invention of steam power did not instantly lead to the disappearance of sailing ships but instead triggered a whole series of improvement in that industry, so the gas lighting industry consolidated its position through incremental product and process innovations.
But electric lighting was also improving and the period between 1886 and 1920 saw many important breakthroughs and a host of smaller incremental performance improvements. In a famous and detailed study (carried out by an appropriately named researcher called Bright) there is evidence to show that little improvements in the design of the bulb and in the process for manufacturing it led to a fall in price of over 80% between 1880 and 1896 (A. Bright, The Electric Lamp Industry Technological change and economic development from 1800 to 1947, Macmillan, New York). Examples of such innovations include the use of gas instead of vacuum in the bulb (1913 Langmuir) and the use of tungsten filaments.
Innovation theory teaches us that after an invention there is a period in which all sorts of designs and ideas are thrown around before finally a ‘dominant design’ settles out and the industry begins to mature. So it was with the light bulb; by the 1920s the basic configuration of the product – a tungsten filament inside a glass gas-filled bulb – was established and the industry began to consolidate. It is at this point that the major players with whom we associate the industry – Philips, General Electric (GE), Westinghouse – become established.
Technological Alternatives
Although the industry then entered a period of stability in the marketplace there was still considerable activity in the technology arena. Back in the nineteenth century Henri Becquerel invented the fluorescent lamp and in 1911 Georges Claude invented the neon lamp – both inventions which would have far-reaching effects in terms of the industry and its segmentation into different markets.
The neon lamp started a train of work based on forming different glass tubes into shapes for signs and in filling them with a variety of gases with similar properties to neon but which gave different colours.
The fluorescent tube was first made commercially by Sylvania in the USA in 1938 following extensive development work by both GE and Westinghouse. The technology had a number of important features including low power consumption and long life – factors which led to their widespread use in office and business environments although less so in the home. By the 1990s this product had matured alongside the traditional filament bulb and a range of compact and shaped fittings were available from the major lighting firms.
Meanwhile, in Another Part of the World…
Whilst neon and fluorescent tubes were variations on the same basic theme of lights, a different development began in a totally new sector in the 1960s. In 1962 work on the emerging solid state electronics area led to the discovery of a light emitting diode – LED – a device which would, when a current passed through it, glow in red or green colour. These lights were bright and used little power; they were also part of the emerging trend towards miniaturisation. They quickly became standard features in electronic devices and today the average household will have hundreds of LEDs in orange, green or red to indicate whether devices such as TV sets, mobile phones or electric toothbrushes are on and functioning.
Development and refinement of LEDs took place in a different industry for a different market and in particular one line of work was followed in a small Japanese chemical company supplying LEDs to the major manufacturers like Sony. Nichia Chemical began a programme of work on a type of LED which would emit blue light – something much more difficult to achieve and requiring complex chemistry and careful process control. Eventually they were successful and in 1993 produced a blue LED based on gallium arsenide technology. The firm then committed a major investment to development of both product and process technology, amassing around 300 patents along the way. Their research culminated in the development in 1995 of a white light LED – using the principle that white light is made up of red, green and blue light mixed together.
So what? The significance of Shuji Nakamura’s invention may not be instantly apparent – and for a long time the only products which could be bought utilising it were small high power torches. But think about the significance of this discovery. White LEDs offer the following advantages:
• 85% less power consumption;
• 16 times brighter than normal electric lights;
• tiny size;
• long life – tests suggest the life of an LED could be 100,000 hours (about 11 years);
• can be packaged into different shapes, sizes and arrangements;
• will follow the same economies of scale in manufacturing that led to the continuing fall in the price of electronic components, so and become very cheap very quickly.
If people are offered a low-cost, high-power, flexible source of white light they are likely to adopt it – and for this reason the lighting industry is feeling some sense of threat. The likelihood is that the industry as we know it will be changed dramatically by the emergence of this new light source – and whilst the names may remain the same they will have to pay a high price for licensing the technology. They may try to get around the patents – but with 300 already in place and the experience of the complex chemistry and processing which go into making LEDs, Nichia have a long head start. When Dr Nakamura left Nichia Chemical for a chair at University of California, Santa Barbara, sales of blue LEDs and lasers were bringing the firm more than $200m a year and the technology is estimated to have earned Nichia nearly $2bn.
Things are already starting to happen. Many major cities are now using traffic lights which use the basic technology to make much brighter green and red lights since they have a much longer life than conventional bulbs. One US company, Traffic Technology Inc., has even offered to give away the lights in return for a share of the energy savings the local authority makes! Consumer products like torches are finding their way into shops and online catalogues whilst the automobile industry is looking at the use of LED white light for interior lighting in cars. Major manufacturers such as GE are entering the market and targeting mass markets such as street lighting and domestic applications, a market estimated to be worth $12bn in the USA alone.
