Mean, median, and mode are different measures of center in a numerical data set. They each try to summarize a dataset with a single number to represent a "typical" data point from the dataset.

Learn how to calculate the mean by walking through some basic examples & trying practice problems.

Practice calculating the mean (average) of a data set. The mean gives us a sense of the middle, or center, of the data.

The mean (average) of a data set is found by adding all numbers in the data set and then dividing by the number of values in the set. The median is the middle value when a data set is ordered from least to …

Explore how we can think of the mean as the balancing point of a data distribution. You know how to find the mean by adding up and dividing. In this article, we'll think about the mean as the balancing point. …

Calculate the mean, median, or mode of a data set!

This Khan Academy article reviews mean, median, and mode concepts with examples to help understand their application in statistics and probability.

Mean absolute deviation The mean absolute deviation of a dataset is the average distance between each data point and the mean. It gives us an idea about the variability in a dataset. Here's how to …

Now I know that the IQR is defined differently from field to field, but as far as I know the quantile function x_p is defined the same for all fields of science or at least in statistical mathematics, so how come …
