Central Tendency: Mean, Median, and Mode
Central Tendency refers to the measure used to determine the center of a distribution data. It is used to find a single score that is most representative of an entire data set.
Mean will be used for almost all occasions. However, outliers can sometimes interfere with usage of the mean.
An outlier is a value that is very different from the other data in your data set.
