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

Practice finding the median of a data set. Like the mean, the median gives us a sense of the middle, or center, of the data.

The mean absolute deviation (MAD) is the mean (average) distance between each data value and the mean of the data set. It can be used to quantify the spread in the data set and also be helpful in …

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 …

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

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

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.

In an exponential function, the output of the function is based on an expression in which the input is in the exponent. For example, f (x) = 2 x + 1 is an exponential function, because x is an exponent of the …

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

In the last video we figured out the mean, variance and standard deviation for our Bernoulli Distribution with specific numbers. What I want to do in this video is to generalize it.
