Simple Question!

Hello oh wise ones...

I've got a stupid question. I am doing a longitudinal analysis. My first wave had around 650 participants and my second wave around 260. I merged the two datasets so I just have answers from those who participated in both waves.

Some of the columns have 0 in them all the end to 650 which falsifies the results obviously.

I have tried deleting the lines but it doesn't seem to work for me.

Please could you help me?

Best wishes
Bellsie

Hello again,

I am getting NaN when doing a Wilcoxon - there are the same number of observations as for all the other variables.

I've attached my data file if anyone could please, please help me?

You're all brilliant!

So I used a simple filter (IFMISS(2id, 0, 1) to use the ID as a way to select only participants with data. This worked. However, the SCOFFTOTAL vs 2SCOFFTOTAL analysis is still coming up as NaN. I did a quick check of the descriptives of these variables and they were identical. I then subtracted one from the other and found a column of zeros - this means these two variables have the EXACT same scores for each and every participant.

If you are expecting these to be different, then you need to check how these variables were created...

I don't undertand why some of the variables are on 656 and others stop at around 250?

I'm sure that there's a simple solution but I think it's biasing by results.
