MEAN DEVIATIONS Meaning and
Definition
-
Mean deviations refer to a statistical measure that calculates the average of the absolute deviations of a set of data points from their mean. It provides information about the dispersion, or spread, of the data. In other words, mean deviations indicate the average distance of each data point from the mean.
To calculate mean deviations, first, the mean or average of the data set is determined. Then, the absolute difference between each data point and the mean is calculated. These differences are then summed up and divided by the total number of data points to find the mean deviations.
Mean deviations are useful in analyzing the variability within a data set. They provide information about how spread out the data points are from the mean, taking into account both positive and negative deviations. A higher mean deviation value indicates a greater dispersion in the data set, while a lower value reflects a smaller spread.
This measure is often used in finance and economics to analyze the risk and volatility of investments. It is also employed in quality control, market research, and various scientific studies. Mean deviations can help researchers compare and evaluate different data sets based on their dispersion, enabling them to make more informed decisions and draw accurate conclusions.

Etymology of MEAN DEVIATIONS
The word "mean deviations" does not have a specific etymology as it is a combination of two separate words: "mean" and "deviations".
The term "mean" comes from the Middle English word "mēne", which was derived from the Old English word "gemǣne" meaning "common" or "shared". In statistics, "mean" refers to the average value of a set of numbers.
The word "deviations" is derived from the Latin word "deviare", meaning "to turn aside" or "to wander". In statistics, "deviations" refer to the differences between individual data points and the mean of a given dataset.
Therefore, when combined, "mean deviations" refers to the average difference or discrepancy of individual data points from the mean value.
