Creating a Box Plot on a Number Line - Part 3 - Q1, Q2, Q3

Sep 30, 2026

Upload by Rowan

Instructions guide the creation of a box plot from multiple sets of numbers. For each numbered dataset (1 through 7), the minimum, maximum, and quartiles are identified to describe distribution shape. Example computations include values such as Min=54, Max=92, Q1=67, Q2=78, Q3=88, along with other sets producing Min/Max and quartile estimates like Q1=51, Q2=69, Q3=84 and Q1=40, Q2=57, Q3=68. The resulting statistics support accurate placement of whiskers and the box on a number line.

FAQs

What is needed to create a box plot from a set of numbers?

You identify the minimum and maximum values, then determine the quartiles Q1, Q2 (median), and Q3 for the same dataset.

How are Q1, Q2, and Q3 used in the box plot?

Q1 marks the left edge of the box, Q2 (the median) marks the line inside the box, and Q3 marks the right edge of the box.

How should the whiskers be drawn on the number line?

Draw whiskers from Q1 to the minimum and from Q3 to the maximum, using the Min and Max values computed for the dataset.
