Detailed explanation-1: -Arithmetic mean is often referred to as the mean or arithmetic average. It is calculated by adding all the numbers in a given data set and then dividing it by the total number of items within that set. The arithmetic mean (AM) for evenly distributed numbers is equal to the middlemost number.

Detailed explanation-2: -The mean is the most familiar and is the arithmetic average, calculated by adding up all the scores and dividing by the total number of scores. The median is the point on the scale that divides the distribution of scores in half (half of the scores fall above the median and half fall below).

Detailed explanation-3: -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-4: -The arithmetic mean, also known as arithmetic average, is the sum of all the values in a list of numerical values divided by the number of items in the list. For example, if we have the two values, eight and six, then their arithmetic average is: 8 + 6 / 2 = 7.

Detailed explanation-5: -The mean can be calculated only for numeric variables, no matter if they are discrete or continuous. It’s obtained by simply dividing the sum of all values in a data set by the number of values. The calculation can be done from raw data or for data aggregated in a frequency table.
