Detailed explanation-1: -The mean in math and statistics summarizes an entire dataset with a single number representing the data’s center point or typical value. It is also known as the arithmetic mean, and it is the most common measure of central tendency. It is frequently called the “average.”
Detailed explanation-2: -When working with a large data set, it can be useful to represent the entire data set with a single value that describes the “middle” or “average” value of the entire set. In statistics, that single value is called the central tendency and mean, median and mode are all ways to describe it.
Detailed explanation-3: -The mean represents the average value in a dataset. The mean is important because it gives us an idea of where the center value is located in a dataset. The mean is also important because it carries a piece of information from every observation in a dataset.
Detailed explanation-4: -The mean can be used to represent the typical value and therefore serves as a yardstick for all observations. For example, if we would like to know how many hours on average an employee spends at training in a year, we can find the mean training hours of a group of employees.
