According to Stanovich (2010), many people understand the necessity of operationism when they think about physics or chemistry. They understand that they must have a way of measuring these things but when people think and talk about psychology, they often fail to recognize the needs for operationism. Why is this a problem or challenge for the future generation?

Postpartum Depression

In this assignment we will look at women with birth depression and how estrogen treatment can affect depression. The data is contained in the data depression footprint.

Prior to treatment, all women were assessed after the Edinburgh Postnatal Depression Scale (EPDS). High EPDS scores indicate severe depression. Patients were randomly assigned to either receive placebo (group = 0, n = 18) or estrogen (group = 1, n = 22) as treatment. The EPDS score was again measured after 3 months of treatment.

In this task you should choose whether to perform a regular two-sample T-test / paired t-test, or if you should also perform a non-parametric test (Wilcoxon-Mann-Whitney test / Wilcoxon pairing test) when we To check if treatment has an effect. To determine this, check the assumptions that are the basis for performing a t-test. For a two-sample t-test, make sure that the two samples are normally distributed and for a paired t-test, be sure to check that the difference between the paired data is normally distributed. Do not use log-transformation in this task, even if it is possible.

1- Give a descriptive description of the variables EPDS prior to treatment initiated for each of the treatment groups (placebo and estrogen). Write a brief summary of what you find. Is there a significant difference between the two treatment groups in EPDS score before receiving treatment?

2- Is there a significant difference between the two treatment groups in 3 months of treatment?

3- Just look at those who have received estrogen as treatment. Have they had a significant change in EPDS score from before treatment to after 3 months of treatment?
4- Now look at those who have received a placebo. Have they had a significant change in EPDS score from before treatment to after 3 months of treatment?
5- Check the change from before treatment to after 3 months of treatment for the placebo and estrogen groups. Perform a test and check whether estrogen has had an effect on the EPDS score.
