One sample, Independent and Paired Sample ttest in Stata

Sir, Good explanation. Thank you for your video. I just want to know what is the advantage of frames over merge?

[@thedatahall]

For merge u will first have to import data into stata, then save a .dta file and then open master file and merge it. Now it looks simple and most of the time ots doesn't matter whether u use frame or merge but when u need to write code that others will use, then u dont have to worry about the working directory or u have to merge multiple files in that case dataframe are quite faster because they dont depend on the speed of your harddrive
