Why do we use mean in statistics?

The mean, also referred to by statisticians as the average, is the most common statistic used to measure the center of a numerical data set. … The mean may not be a fair representation of the data, because the average is easily influenced by outliers (very small or large values in the data set that are not typical).

What are the uses of mean?

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.

Where is mean used in real life?

The mean is often used in research, academics and in sports. When you watch a baseball game and you see the player’s batting average, that number represents the total number of hits divided by the number of times at bat. In other words, that number is the mean.

What is the advantages and disadvantages of mode?
