â Frequently Asked Questions
Mean is the sum of all values divided by the count (arithmetic average), while median is the middle value when data is sorted. Median is less affected by outliers than the mean.
Standard deviation measures data spread â it is the square root of the variance, which is the average of squared deviations from the mean. A low SD means data clusters tightly around the mean.
