I am currently receiving more and more data for my research, and I already created a list of variables, which includes items (e.g. enjoyment1, enjoyment2, enjoyment3, ...) and several computed variables (e.g. Means of Enjoyment, involvement, ...). When I try to add more data to my SPSS data file, It seems that I am not able to extend the formula I used for computing variables into the new data points. Therefore, I need to compute the variables again.
I was wondering if there is a way to just extend a computation down a column in my dataset.
