Assignment
The hypothesis being tested is: Women who are working will have a lower level of depression as compared to women who are not working.
Using Polit2SetC SPSS dataset, which contains a number of mental health variables, determine if the above hypothesis is true.
Follow these steps when using SPSS:
• Open Polit2SetC dataset.
• Click Analyze then click Compare Means, then Independent Sample T-test.
• Move the Dependent Variable (CES_D Score "cesd") in the area labelled Test Variable.
• 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.
• Click continue and then click OK.
Task: Through analysis of the data and use of the questions below write one to two paragraphs summarizing your findings from this t-test.
• How many women were employed versus not employed in the sample?
• What is the total sample size?
• What are the mean (SD) CES-D scores for each group?
• Interpret the Levene's statistic. (Hint: Is the assumption of homogeneity of variance met? Are equal variances assumed or not assumed?)
• What is the value of the t-statistic, number of degrees of freedom and the p-value?
• 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:
• Open Polit2SetC dataset.
• Click Analyze then click Compare Means, then Paired Samples T-test.
• 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).
• Click continue and then click OK.
Through analysis of the data and use of the questions below write one to two paragraphs summarizing your findings from this t-test.
• What is the total sample size?
• What are the mean (SD) CES-D scores at wave 1 and wave 2?
• What is the mean difference between the two time periods?
• What is the value of the t-statistic, number of degrees of freedom and the p-value(sig)?
• 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:
• Open Polit2SetC dataset.
• Click Analyze then click Compare Means, then Independent Sample T-test.
• 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.
• 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 or GED). Click on Define
