1. Open Polit2SetC dataset.

2. Click Analyze then click Compare Means, then Independent Sample T-test.

3. Move the Dependent Variable (CES_D Score “*cesd”*) in the area labelled Test Variable.

4. Move the Independent Variable (Currently Employed “*worknow”*) into the area labelled Grouping Variable. The worknow variable is coded as (0= those women who do not work and 1= those women who are working). Click on Define Groups in group 1 box type 0 and in group 2 box type 1. Click Continue.

5. Click continue and then click OK.

Assignment: Through analysis of the data and use of the questions below write one to two paragraphs summarizing your findings from this t-test.

1. How many women were employed versus not employed in the sample?

2. What is the total sample size?

3. What are the mean (SD) CES-D scores for each group?

4. Interpret the Levene’s statistic. (Hint: Is the assumption of homogeneity of variance met? Are equal variances assumed or not assumed?)

5. What is the value of the t-statistic, number of degrees of freedom and the p-value?

6. Does the data support the hypothesis? Why or why not?

__Part II__

Hypothesis: Women who reported depression scores in wave 1 and wave 2 of the study did not have a significant difference in their level of depression.

Using Polit2SetC SPSS dataset, determine if the above hypothesis is true.

Follow these steps when using SPSS:

1. Open Polit2SetC dataset.

2. Click Analyze then click Compare Means, then Paired Samples T-test.

3. First click on CES-D Score (*cesd*) and move it into the box labelled Paired Variables (in the rectangle for Pair 1 of Variable 1 and then click on CESD Score, Wave 1 (*cesdwav1*) and move it into the Paired Variables box (in the rectangle next to CES-D Score, pair 1, variable 2).

4. Click continue and then click OK.

Assignment: Through analysis of the data and use of the questions below write one to two paragraphs summarizing your findings from this t-test.

1. What is the total sample size?

2. What are the mean (SD) CES-D scores at wave 1 and wave 2?

3. What is the mean difference between the two time periods?

4. What is the value of the t-statistic, number of degrees of freedom and the p-value(sig)?

5. Does the data support the hypothesis? Why or why not?

__Part III__

Using Polit2SetC dataset, run independent groups t-tests for three outcomes. The outcome variables are CES-D Score (*cesd*), SF12: Physical Health Component Score, standardized (*sf12phys) *and SF12: Mental Health Component Score, standardized (*sf12ment*).

Follow these steps when using SPSS:

1. Open Polit2SetC dataset.

2. Click Analyze then click Compare Means, then Independent Sample T-test.

3. Move the Dependent Variables (CES_D Score “*cesd”,* SF12: Physical Health Component Score, standardized (*sf12phys), *and SF12: Mental Health Component Score, standardized (*sf12ment*)* *) in the area labelled Test Variable.

4. Move the Independent Variable (Educational Attainment *“educatn”*) into the area labelled Grouping Variable. The educatn variable is coded as (1= no high school credential and 2=diploma or GED). Click on Define Groups in group 1 box type 1 and in group 2 box type 2. Click Continue.

5. Click continue and then click OK.

Assignment: Create a table to present your results, use the table 6.3 in Chapter 6 as a model. Write one or two paragraphs explaining your results.
