The Five-Number Summary of Positions Summarize positions that help to describe center and variability of a distribution. Minimum value First quartile (Q1) Median Third Quartile Maximum Value The Box Plot is a graphic device that visually presents the following elements: the range, the IQR, the median, the quartiles, the minimum (lowest value,) and the maximum (highest value.) The boxplot provides information about the center, spread, and symmetry or skewness of the data. Watch the video in generating the five-number summary and creating a boxplot, https://www.youtube.com/watch?v=39lsUsJsc2c&t=113s, How to Create a Box Plot in Excel.

Definition Definition Middle value of a data set. The median divides a data set into two halves, and it also called the 50th percentile. The median is much less affected by outliers and skewed data than the mean. If the number of elements in a dataset is odd, then the middlemost element of the data arranged in ascending or descending order is the median. If the number of elements in the dataset is even, the average of the two central elements of the arranged data is the median of the set. For example, if a dataset has five items—12, 13, 21, 27, 31—the median is the third item in ascending order, or 21. If a dataset has six items—12, 13, 21, 27, 31, 33—the median is the average of the third (21) and fourth (27) items. It is calculated as follows: (21 + 27) / 2 = 24.
