![]() ![]() The question is how do we select only female cases, thereby excluding males from any tests that we run? Select Cases But the trouble is our sample contains data for both males and females, and any tests we run will be on that basis. ![]() We want to compare this to the average time for women in our sample. Imagine we already know that in the population as a whole the average amount of time it takes for a woman to fall asleep is 8.15 minutes. The two variables we’re interested in here are Sex, either male or female, and Duration, which is the number of minutes that elapses from the start of a statistics lesson before a subject falls asleep. The data we’re using for this tutorial comes from a hypothetical study that examines how long it takes people to fall asleep during a statistics lesson. In this tutorial, we’ll look at how to select cases in SPSS, and how to work with the resultant filtered data.
