Mean statistics

Calculate the mean, or average, of a set of numbers using the mean calculator. Plus, learn the formula to find the average and see examples.

Mean for grouped data

Most of the data we deal with in real life is in a grouped form. The amount of data is generally large and is associated with corresponding frequencies (sometimes we divide data items into class intervals). Here, we will be studying methods to calculate range and mean deviation for grouped data.

The empirical rule states that for normal distributions, 68% of data lie 1 standard deviation of the mean, 95% within 2, and 99.7% within 3.

Median Mode Mean and Range. Median is the middle number in a list of numbers. Mode is the number that appears most in the list. Mean is the average.

Scientists don't always use normal words when explaining their research to the public. Here's a quick and easy to guide to understanding those words for people who aren't scientists.
