The total sample size is 960. Out of the sample size, 524 women are unemployed versus 436 women are employed. The standard deviation of each group is 12.46 for unemployed women and 15.82 for employed women. The significant level of the two variables is 0.000 less than .05 showing that there is no statistically significant difference between them showing that there is no statistical difference between their means. Since the Sig is < .05, the study agrees that Equal variances not assumed. The value of the t statistic is 6,825 and p-value is 0.000, and number of degrees of freedom is .74326 and .72949. (Kent State University, 2016).

The total sample size is 157. The standard deviation for the (SD) CES-D scores at Wave and Wave 2 are 11.87 and 11.49 respectively.
The mean difference between the two time periods is 0.7172. The value of t-statistic is .709, the number of degree of freedom is 1.0119 and the p-value (sig) is .480. The data support the hypothesis because p-value is greater that 0.05.

The sample size is 2,650. The overall mean is 219.21. The overall SD is 66.16 and Std Error Mean is 3.12. The p-value of physical health component is less than 0.05 showing that the Equal variances not assumed. However, a p-value of Mental Health Component is more than 0.05 revealing that the Equal variances are assumed. The number of degree of freedom is between .72 and .76.
