Why are degrees of freedom (n-1) used in Variance and Standard Deviation
Tutorial on how to understand degrees of freedom and why n-1 is used instead of just n for sample variance. Includes the reason why n-1 is use for a sample, but for the population variance. Video includes a visual and numerical example. The n-1 is used to adjusted the variance because of the error between the sample mean and the population mean.
