How do you choose a random sample?Publicerat den 12 november, 2015
We work only with non-name-related data (such as employee numbers). Shortly before a test, we receive employee numbers from the workplace and randomly select the agreed number of test subjects. Since NDP make this selection, there is no reason for anyone to suspect that someone at the company is “singling people out”. We are completely neutral and don’t know who the random number generator will select.
