The mean deviation (also called the mean absolute deviation) is the mean of the absolute deviations of a set of data about the data's mean.For a sample size, the mean deviation is defined by. (1). where is the mean of the distribution. The mean deviation of a list of numbers is implemented in the Wolfram Language as.he mean deviation (also called the mean absolute deviation) is the mean of the absolute deviations of a set of data about the data's mean. For a sample size, the mean deviation is defined by.
Variance and standard deviation are very closely related. In order to calculate standard deviation, you first need to find variance. Variance is the average squared distance between each data point and the mean. It is given in squared units (e.g. mm 2). Standard deviation is the square root of the variance. It's units are given as basic units of measurement (e.g. mm). Standard deviation represents the âtypicalâ (though not âaverageâ) distance between the mean and the data points in the sample. It can be thought of as measuring the spread of data.
