Hi ,
1.what is the purpose of doing z test ,or t test.
I mean after doing it how can we use the results of the test …My thoughts abt the tests are…
please correct me … in the context of below assumptions I am trying to make.We do z test or t test on the data we have.
To validate if the data we have is genuine or not.Can we make samples out of our data which are further used to build models and test models.… it has also something to do with missing value imputations… since we are using mean, or mode most of the times…
