Mean, median, and mode are three common measures of central tendency used to summarize a data set with a single representative number.

• Mean : Also known as the average, the mean is found by adding all the numbers in the data set and then dividing by the total number of values. It represents the arithmetic average of the data points

• Median : The median is the middle value in an ordered data set. To find it, you first arrange the numbers from smallest to largest and then select the middle number. If there is an even number of values, the median is the average of the two middle numbers

• Mode : The mode is the number that appears most frequently in the data set. A data set may have one mode, more than one mode, or no mode if all numbers occur with the same frequency

In summary, the mean gives the average value, the median identifies the midpoint, and the mode shows the most common value in a data set
