📈 Average Calculator
Calculate mean, median, mode, range, and more from any set of numbers.
Average Calculator
This calculator computes multiple measures of central tendency and spread for any data set. Enter your numbers to get the count, sum, mean (arithmetic average), median, mode, range, minimum, and maximum values instantly.
Understanding these different averages helps you analyze data more effectively. The mean is the most common average, but it can be skewed by outliers. The median gives the middle value and is more robust. The mode shows the most frequent value. Together, they give a complete picture of your data's distribution.
Frequently Asked Questions
What is the difference between mean, median, and mode?
The mean is the average (sum divided by count). The median is the middle value when data is sorted. The mode is the most frequently occurring value. For example, in {2, 3, 3, 5, 12}: mean = 5, median = 3, mode = 3.
What is the range?
The range is the difference between the highest and lowest values in a data set. For {4, 8, 15, 23, 42}, the range is 42 - 4 = 38. It gives a quick measure of how spread out the data is.
When should I use median instead of mean?
Use the median when your data has outliers or is skewed (e.g., income data where a few very high earners pull the mean up). The median is more resistant to extreme values and better represents the "typical" value in such cases.
