Find n in statistics

WebWhen instructor calculated standard deviation (std) he used formula for unbiased std containing n-1 in denominator. If you have the whole data (or almost the whole) there are also another way how to calculate correlation. In this case you must use biased std which has n in denominator. And in overall formula you must divide by n but not by n-1. WebFree math problem solver answers your statistics homework questions with step-by-step explanations.
