Analysis of Experimental Data

[Lale Mur]

Hello, I have conducted survey experiments in public, and now I need to analyse the data that I exported from Qualtrix. Up to now, I have used Stata for observational data, and it has been quite straightforward, doing regression analyses, etc. But now I am totally lost. Although I have imported the cvs file into Stata and the dataset seems ok, I do not know how to make sure to do the "difference in means" with different experimental group means. I cannot get my head around that. I would appreciate if someone could walk me through that. Thank you so much! Regards, L

If you do not already have it, please install the -dataex- command (-ssc install dataex-), and read -help dataex- for the instructions on how to use it to post a small representative sample of your data. If the variables in your example data are not labeled, also give an explanation of what they are and what role they play in your study. Be sure, most important, to explain what particular questions you are trying to answer in your study.
