How do I read a box plot?

A boxplot is a way to show a five number summary in a chart. The main part of the chart (the “box”) shows where the middle portion of the data is: the interquartile range. At the ends of the box, you” find the first quartile (the 25% mark) and the third quartile (the 75% mark). The far left of the chart (at the end of the left “whisker”) is the minimum (the smallest number in the set) and the far right is the maximum (the largest number in the set). Finally, the median is represented by a vertical bar in the center of the box.

Box plots aren’t used that much in real life. However, they can be a useful tool for getting a quick summary of data.

How to Read a Box Plot: Steps

Step 1: Find the minimum.

The minimum is the far left hand side of the graph, at the tip of the left whisker.  

Step 2: Find Q1, the first quartile.

Step 3:  Find the median.

Step 4: Find Q3, the third quartile.

Step 5: Find the maximum.

hope this helps!!
