Mean, Median & Mode Calculator
Compute mean, median, mode, range & standard deviation -- with step-by-step solutions.
About this calculator
Enter numbers separated by commas or spaces. Handles integers and decimals. Standard deviation uses population formula (σ, not s). For sample standard deviation, divide by n−1 instead of n.
What are mean, median, and mode?
The mean (average) is the sum of all values divided by the count. The median is the middle value when numbers are sorted. The mode is the value that appears most frequently. These three measures of central tendency give different perspectives on a data set. Standard deviation measures how spread out values are around the mean.
