What is a Mean, Median, Mode Calculator?

A descriptive statistics calculator computes central tendency metrics including mean, median, mode, range, and sum for any numerical dataset.

Mean is the arithmetic average. Median is the middle value when data is sorted. Mode is the most frequently occurring value in the dataset.

Mean (x̄) = Sum of all values (Σx) / Total number of values (n).

Sort the data set, take the two middle numbers, and calculate their average: Median = (M1 + M2) / 2.

Yes. Datasets can be unimodal (1 mode), bimodal (2 modes), multimodal (3+ modes), or have no mode if all values appear equally.

Median is preferred because it is resistant to extreme outliers and skewed distributions.

Range = Maximum Value - Minimum Value.

A mean calculated after removing a small percentage (e.g. 5%) of the highest and lowest outliers.

Weighted Mean = Σ(x * w) / Σw, where w represents the weight of each observation.
