I'm trying to figure out the best way to conduct t-tests between some descriptive statistics of my original sample and my final sample after data cleaning. Essentially, I want to see how representative my final sample is of my original sample. My data set is large, so unfortunately I can't manually track the variables that are getting dropped and adjust the spreadsheets. I see that there are some old posts on this topic from a number of years ago, but I did not find them helpful and I just wanted to see if there might be some better or newer approaches to this. Thank you!
