More Information
Population variance is a measure of how data points differ from the population mean. It is different from sample variance, as population variance uses the entire population data set.
Tips
Ensure you are using the entire population dataset. Confusing population variance with sample variance, which divides by (n-1) instead of n, is a common mistake.
