RESEARCH METHODOLOGY

Detailed explanation-1: -The average deviation of a set of scores is calculated by computing the mean and then the specific distance between each score and that mean without regard to whether the score is above or below the mean. It is also called an average absolute deviation.

Detailed explanation-2: -The average absolute deviation (AAD) of a data set is the average of the absolute deviations from a central point.

Detailed explanation-3: -The mean deviation is also known as the mean absolute deviation and is defined as the mean of the absolute deviations of the observations from the suitable average which may be the arithmetic mean, the median or the mode.

Detailed explanation-4: -Mean deviation is a statistical measure used to give the average value of the absolute deviation with respect to the central point of the data. Mean deviation can be calculated about the mean, median, and mode.
