For today's assignment, I would like for you to download the following data set: click here to download personality trait data. The information regarding the variable names is provided on the following web page: variable names. This data set contains the data you provided last week on personality, health, and life satisfaction.

Once you've downloaded the data set and opened it in SPSS, I would like for you to work on the following questions. Please jot your answers down on a spare sheet of paper and turn it in to your TA at the end of the session.

1. Create a composite variable for life satisfaction. Life satisfaction is measured with 5 items, each of which are keyed in the "proper" direction. Create the composite and then compute the mean and standard deviation of the composite scores and report those in the sheet you turn in at the end of the session.

2. Create a composite variable for the trait Openness to Experience (i.e., the extent to which people are intellectual, creative, and open to new ideas). The following items are relevant for this composite:

vbfi10, vbfi12*, vbfi15, vbfi22, vbfi23, vbfi25, vbfi32, vbfi35, vbfi44

I have used an * to denote which items should be reverse keyed.

Once you've created the composite, compute the mean and standard devistion and report that in the sheet you turn in. Also, create a histogram of the scores and sketch that on the page.

3. Do men and women have comparable scores on Life Satisfaction? Compute the mean (and SD) for men and women seprately and express the difference both as a mean difference and via Cohen's d. Show your work.
