You can drag and drop (as above) or use the up arrow in the middle of the dialog. ItвЂ™s necessary to get the Rv.Uniform function into the Numeric Expression box at the top of the dialog box. Or, to put it a different way, it will generate a random number between two limits, where every possible value between the limits is equally likely to be generated. This returns a random value from a uniform distribution with a specified minimum and maximum value. The function we need is called Rv.Uniform. This will bring up a set of functions, all of which operate to generate different kinds of random numbers. Once youвЂ™ve named your target variable, select Random Numbers in the Function group on the right. This is the variable that SPSS will create to hold the set of random numbers. You need to do a number of things to set up this dialog box so SPSS will generate random numbers.ДЇirst, name your target variable.

To generate a set of random numbers, weвЂ™re going to use SPSSвЂ™s Compute Variable dialog box.

The DataДЄs a starting point, you should at leastВ have an ID variable populated in the Data View of SPSS.
