In this section i’ll describe one of the most useless tests in all of statistics: Your variable of interest should be continuous and normally distributed, and you must know the average and spread (or standard deviation) of the population. The tool also compares the sample data to the standard deviation, calculates the test power, checks data for normality and draws a histogram and a distribution chart. University of new south wales. It is used when the population standard deviation is known. It can be used to make a judgement about whether the sample differs significantly on some axis from the population from which it was originally drawn.
