Descriptive Statistics Calculator
Calculate all key descriptive statistics from up to 10 data values. Get the mean, median, mode, range, variance, standard deviation, minimum, and maximum in one step.
Descriptive statistics summarize a dataset with a few key numbers, giving you a clear picture of the data's center, spread, and shape.
Measures of Center: The mean (arithmetic average) is the sum divided by count. The median is the middle value when sorted, and is more robust to outliers. The mode is the most frequent value.
Measures of Spread: The range (max minus min) gives the total spread. Variance measures the average squared deviation from the mean, and standard deviation is its square root, expressed in the same units as the data. This calculator uses sample variance (dividing by n-1) rather than population variance (dividing by n), which is appropriate when your data is a sample from a larger population.
