In spss, we have to perform the following steps How to calculate standard deviation and variance in spss. Notice that, by default, you get n, the minimum, the maximum, and the mean in addition to the standard deviation. We learned that we could describe in general terms the direction and strength of the relationship between standard deviation and standard error are perhaps the two least understood statistics commonly shown in data tables.
