Hi,
Concerning the survey, i would like to have your opinion about the stastiscal viability of my method. The building population (1000) is made up of different departments with their own area in the building. We have defined a number X of individuals to interview per derpartements depending its workforce. During the last day of the week, we want to travel in the building and submit the survey to X persons randomly seleced in each departments (X depending of the departement).

According to you, Does this method seem acceptable ? Does the test population enough choose in a random way ?

Thank you.
