As you can see, the Mean, Number of Cases, and Standard Deviation are pre-selected for you. You can get other statistics if you want from the left column, but we will stick with those three items only. Select Continue and then Ok (ignore the \"Style and \"Bootstrap options). Output of the \"Means\" Procedure in SPSS You will see two tables containing all the data generated by the means procedure in SPSS. Case Processing Summary This table provides the N for us. It isn't all that important, so I recommend ignoring it.

That's our first way of getting means. Not too hard, right? When getting the mean and standard deviation for dependent variables like dollar amount recalled (where I want to look at differences between High versus Low independent variable conditions), I recommend using this \"Means procedure. Keep in mind that this procedure doesn't tell us if the groups differ from each other statistically. It only tells us the average amount of money spent on books (and the standard deviation). Some statistical tests (like the -Test) automatically give us descriptive statistics, while others (like the ANOVA) provide us with the option of getting descriptive statistics. We will look at these options in Crash Course Quizzes #2 and #3. |1 O Descriptive Statistics > Descriptives ... on the top menu as shown below.

In this case, I prefer to look at my dependent variables (time to help, participant age, and participant gender). You should notice that there is no box to separate the levels of your independent variable in this descriptives test. Thus, you will NOT be able to get means and standard deviations for each of your separate condition (High versus Low), but you will get the TOTAL score for ALL participants regardless of their condition. OK, let's move them over.

Again, you should notice that there is no place for your independent variable in this "Frequencies" procedure.
