What are Mean, Median, and Mode?

Mean is the average of all values. Median is the middle value when data is sorted. Mode is the most frequently occurring value. These measures of central tendency help summarize datasets and identify patterns. They are fundamental concepts in statistics, data analysis, and research, used in everything from business analytics to scientific research.

How to use

输入您的 dataset values separated by commas, spaces, or new lines. The 计算器 computes mean, median, mode, range, variance, standard deviation, quartiles, and interquartile range. It also identifies skewness to help you understand the distribution shape of your data.

常见问题

What is the difference between mean, median, and mode?

The Mean is the average of all numbers (sum divided by count). The Median is the middle value when numbers are sorted. The Mode is the number that appears most frequently in the dataset.

How should I format my input data?

You can separate numbers using commas, spaces, or new lines. For example, you can enter '1, 2, 3' or '1 2 3' or paste a vertical list from a spreadsheet.

Can I use decimal numbers?

Yes, the calculator fully supports decimal numbers. You can input values like 3.5, 10.25, or 0.01 just like whole numbers.

What if there is no mode?

If no number in your dataset repeats, there is no mode. The calculator will display 'No mode' or 'None' for the mode result.

How does the calculator handle an even number of values for the median?

When the dataset has an even number of values, the median is calculated as the average of the two middle numbers.

What happens if there are multiple modes?

If multiple numbers appear with the same highest frequency, the dataset is multimodal. The calculator will list all relevant modes (e.g., '2, 4').
