Frequently Asked Questions
What is the difference between sample and population statistics?
Population variance and standard deviation divide by N (the whole group), while sample statistics divide by N−1 to correct bias when you only have a sample of the data.
How is the median found?
Sort the numbers; the median is the middle value, or the average of the two middle values when the count is even.
