hello Dr. greetings!! thanks for your nice and well-versed presentation. but i have one question, how to add meta-analysis package in spss?

Ordinal data is categorical/discrete. Does PCA work with discrete data? As far as I know discrete data is allowed only after one-hot-encoding. But you did not mention one-hot-encoding.

Thank you for such an informative and clear video. I have two questions: firstly, by adding the data of a study when we have two different time points, should we enter the post-test measurement data? I mean, don't we need to enter the baseline measurement data? and secondly, what if one study among all, has three time point measurements? How the comparison can be made in this case?

How would I calculate the SD values if the studies of my systematic review don't tell me the SD, they only show the Mean values. Thank you very much for the video!
