2. Mean Absolute Deviation: Definition, Finding & Formula
Link: https://statisticsbyjim.com/basics/mean-absolute-deviation/
Description: WEBThe mean absolute deviation (MAD) is a measure of variability that indicates the average distance between observations and their mean. MAD uses the original units of the data, which simplifies interpretation. Larger values signify that the data points spread out further from the average.

Description: WEBHere's how to calculate the mean absolute deviation. Step 1: Calculate the mean. Step 2: Calculate how far away each data point is from the mean using positive distances. These are called absolute deviations. Step 3: Add those deviations together. Step 4: Divide the sum by the number of data points.

Description: WEBThe absolute deviation, variance and standard deviation are such measures. The absolute and mean absolute deviation show the amount of deviation (variation) that occurs around the mean score. To find the total variability in our group of data, we simply add up the deviation of each score from the mean.

6. Deviation (statistics) - Wikipedia
Link: https://en.wikipedia.org/wiki/Deviation_(statistics)
Description: WEBThe absolute value of the deviation indicates the size or magnitude of the difference. In a given sample, there are as many deviations as sample points. Summary statistics can be derived from a set of deviations, such as the standard deviation and the mean absolute deviation, measures of dispersion, and the mean signed deviation, a measure of bias.

Description: WEBJul 13, 2022 · The mean absolute deviation (mean deviation about the mean) is a measure of the degree of dispersion of data values. It involves measuring the absolute difference between the data values from the mean and taking the average of these differences. Thus the mean absolute deviation measures the “average” distance of the …
