    It is really easy to find out coefficient of variation in your SPSS research. I am sure you know about coefficient of variation. However, I am explaining it for your information.

    According to the SPSS help book, they determined the coefficient of variation in the way that “The ratio of Standard Error of the estimate to the estimate”. It could be difficult to understand this to some people. But if I say that to find out the coefficient of variation, you should know the standard deviation first. The formula of coefficient of variation is to divide this standard deviation with mean and then multiply with 100, you will find the coefficient of variation where standard deviation will always show a positive mean called as arithmetic mean.

    However, as you wanted to know how you can do this in SPSS, my answer is do it the simplest way. If your SPSS research data contain complex sample descriptive, then from the Menu chose analyze. Then select complex sample descriptive and you will find some options. Put your expected variables in Measures and dependent variable in Subpopulation box. In the bottom of the box, you will see the three options. The first one is statistics, second one is Missing values and third one is Options. Chose Statistics. A new dialogue box will be opened and you will find some options. From the statistics options, you will find standard error, unweighted count etc. as well as you will see the option for Coefficient of variation. Select it and click on continue. Then click on Ok. You will find the result which will show the all findings according to your selection. In that way you can calculate coefficient of variation. However, sometimes you need to calculate it in another ways based on your SPSS research data set.
