What are the Measures of Central Tendency?
Some examples of Measures of Central Tendency are mean, median and mode.

What is the mean?
The mean is the average. To calculate the mean or average of a group of numbers, first add all the numbers, then, divide by the number of values. The mean or average is the most common measure to describe the center of a frequency distribution. The mean is influenced by all data in a study. For this reason, it works best for symmetrical distributions of data where there are no outliers or extremes.

What is the median?
The Median is the value in the middle of a set of data. If there is an even number of values then divide the two numbers in the middle by 2.

What is the Mode?
The Mode is the most frequent value, number or category in a set of data.
