Detailed explanation-1: -The Mean is the arithmetic average of the scores ( a.k.a. the “arithmetic mean"). It is equal to the total of all values divided by the number of values. The Median is the score that divides the numerical distribution in half, where 50% of the values fall below and 50% fall above.

Detailed explanation-2: -Central tendency is a statistical measure that identifies a single score as representative of an entire distribution. The goal of central tendency is to find the single score that is most typical or most representative of the entire group.

Detailed explanation-3: -The central tendency measure is defined as the number used to represent the center or middle of a set of data values. The three commonly used measures of central tendency are the mean, median, and mode. A statistic that tells us how the data values are dispersed or spread out is called the measure of dispersion.

Detailed explanation-4: -When is the mean the best measure of central tendency? The mean is usually the best measure of central tendency to use when your data distribution is continuous and symmetrical, such as when your data is normally distributed.
