What are Mean, Median, and Mode?
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.

Frequently Asked Questions
What's the difference between mean, median, and mode?
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.
How is the median calculated for even number of values?
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.
Can a dataset have multiple modes?
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.
What input formats are supported?
You can enter numbers separated by commas, spaces, semicolons, tabs, or line breaks. The calculator automatically parses different formats and validates the input data.
How accurate are the calculations?
The calculator provides high precision results with up to 4 decimal places, automatically removing trailing zeros for cleaner display while maintaining mathematical accuracy.
