Detailed explanation-1: -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.
Detailed explanation-2: -You find the mean (informally called the average) by adding up all the numbers in a set and then dividing by how many values there are. When you arrange a set of values from smallest to largest, the median is the one in the middle. The mode is simply the value that occurs the most in the set.
Detailed explanation-3: -The arithmetic mean is the simplest and most widely used measure of a mean, or average. It simply involves taking the sum of a group of numbers, then dividing that sum by the count of the numbers used in the series. For example, take the numbers 34, 44, 56, and 78. The sum is 212.
