Mean, Median, Mode Calculator
Calculate the mean, median and mode of any data set at once. For 4, 8, 6, 5, 3, 8: mean = 5.67, median = 5.5, mode = 8.
Standard Deviation Calculator
Calculate standard deviation and variance for any set of numbers, sample or population. For 2, 4, 4, 4, 5, 5, 7, 9 the mean is 5 and the population standard deviation is exactly 2.
