Frequently Asked Questions
What is the difference between mean, median, and mode?
Mean is the arithmetic average (sum / count). Median is the middle value when data is sorted — it is not affected by extreme values. Mode is the most frequently occurring value. For symmetric distributions they are equal; for skewed data they differ.
When should I use median instead of mean?
Use median when your data has outliers or is skewed. For example, household income uses median because a few very high earners would inflate the mean. The median better represents the "typical" value in skewed datasets.
Can there be multiple modes?
Yes. A dataset can be unimodal (one mode), bimodal (two modes), or multimodal (more than two). If all values appear the same number of times, there is no mode. This calculator shows all modes.
What is the range?
The range is the difference between the maximum and minimum values in a dataset. It measures the spread of the data but is sensitive to outliers. Range = Max - Min.
How do I enter data?
Enter your numbers separated by commas, spaces, or newlines. For example: 5, 10, 15, 20 or 5 10 15 20. The calculator handles any combination of these separators.
