Understanding Central Tendency: Mean, Median, Mode, and Range

Learn how to calculate mean, median,and mode of a data set. In addition, I cover how to calculate range. Mean, median, and mode are all measures of central tendency. A measure of central tendency is a single number that is used to summarize all the values of a data set.
Mean is the average of a data set
Median is the number in the middle of the data set and mode is the number that occurs most often.
The range is the difference between the least and greatest number in a data set.
