In this video, I'll show you how to calculate a mean score as a variable. So say I have these four satisfaction scores, all four are like our scale variables from a questionnaire. And I want to tabulate a variable which represents the mean score for each participant. So from the transform menu, I'm going to choose compute variable. I need to give my new variable a name. I'm going to call it mean satis. Remember, it can't have spaces or special characters. Now in this numeric expression box is where I'm going to tabulate my mean. There is a function in spss and if you click on all and then in the bottom there, find mean. If you hit M, it takes you straight down to all the M's. Once you find mean, you can either double click or you can use the arrow to move it up into the expression box. Now we're going to replace these question marks with the variables that we want to find the mean score for. So I'm going to use all four of these variables here. So I click on the first one, move it over. I'm going to highlight the next question mark and I'm going to click on the second variable and move it over. Now I have more than two, so I'm going to separate them with a comma. So I've got a comma and then I click on the third variable, another comma and then the fourth variable. And now I'm finished. I will find the mean of all four of these scores. So when you're done, go ahead and click OK. Go back to your data file and you'll see I have a new variable called mean satis. If I double click, I can go straight to the variable view. Make sure my level of measurements correct. It is scale, which is right and I'm going to give it a new label. I'm going to call it mean satisfaction score. The decimal places I'm going to leave us to, if I go back to my data view, once again I can see that I have a new variable which represents the mean of all four satisfaction scores.
