Mean, median, and mode are the three main measures of central tendency in statistics. The mean is the arithmetic average of all values, calculated by adding all numbers and dividing by the count. The median is the middle value when numbers are arranged in order. The mode is the value(s) that appear most frequently in the dataset. These measures help understand the central or typical value in a collection of data.

Multiple Input Formats
Enter data using various separators (commas, spaces, semicolons, line breaks) for maximum flexibility and convenience.
Mean is the arithmetic average (sum ÷ count), median is the middle value when data is sorted, and mode is the most frequently occurring value(s). Each measure provides different insights into your data's central tendency.
When there's an even number of values, the median is the average of the two middle values. For example, in the dataset [1, 2, 3, 4], the median is (2 + 3) ÷ 2 = 2.5.
Yes, a dataset can be unimodal (one mode), bimodal (two modes), multimodal (multiple modes), or have no mode if all values appear with the same frequency.
You can enter numbers separated by commas, spaces, semicolons, tabs, or line breaks. The calculator automatically parses different formats and validates the input data.
The calculator provides high precision results with up to 4 decimal places, automatically removing trailing zeros for cleaner display while maintaining mathematical accuracy.
