Mean Calculator

Calculate the mean (average), median, mode, and other statistical measures for your data set. Enter numbers separated by commas, spaces, or line breaks to get comprehensive statistical analysis.

Understanding Statistical Measures

Measures of Central Tendency

• Mean (Average): Sum of all values divided by the number of values
• Median: Middle value when data is arranged in order
• Mode: Most frequently occurring value(s)

Measures of Spread

• Range: Difference between maximum and minimum values
• Standard Deviation: Measure of how spread out the data is
• Variance: Square of the standard deviation
• Quartiles: Values that divide the data into four equal parts

Statistical Formulas

• Mean: μ = (Σx) / n
• Standard Deviation: σ = √[(Σ(x - μ)²) / n]
• Variance: σ² = (Σ(x - μ)²) / n
• Range: Max - Min
