In Statistics, there are three Measures of Central Tendency: Mean, Median and Mode. Mean is defined as the average value of a dataset. It is the sum of all values of a series divided by the number of valuesa in that series. Median is the middle value of a dataset when it is arranged in either ascending or descending order. Mode represents that value that occurs most frequently in the dataset. A dataset may have more than one mode in some cases, and none in other cases.

Below is a list of multiple-choice questions and answers on Measures of Central Tendency to help students understand the topic better.
