Structural Equation Modeling

Structural equation modeling (SEM) is a powerful, multivariate technique found increasingly in scientific investigations to test and evaluate multivariate causal relationships. SEMs differ from other modeling approaches as they test the direct and indirect effects on pre-assumed causal relationships. This course will provide you with comprehensive explanation of structural equation modeling.

Please help!
I wanted to do following and need your help:
1. How to create demographic information tabel. Like age, gender, country, religion etc. Including means, SD, Range, percentage, N and so on ? Just like in scientific Artikel.
2. How to filter some part of data. For example we collected the data in 3 different times over a period of one year. So basically there are some people who did participate in 1. experiment but didn't in time 3 i mean they didn't continue the whole year. Now i just want to compare the 1. Times and the 3. Times of the persons who took part in all 3 times and not only once.
How can i filter or select only those, who did the whole experiment?
3. How can i compare the first time with the second time or 3rd time to see if there's any difference between in case of health situation. I mean if they were healthy at the beginning are the now seek and vice versa?
I wanted to do T, test.
Can you please tell me what kind of test do i need to do?
Im writing my bachelor thesis in psychology and have no clue of SPSS. Please help me and send some videos that show this Prozesse. Thanks for your help 👍
