# How do you create box and whisker plots on a graphing calculator?

##### 1 Answer

For a procedure similar to the graphing calculator, see this Plot.ly link . Please explore the Data tab, after reading the detailed explanation below.

**Explanation** . I never used graphing calculators, because in my country they are considered detrimental to actual mathematical reasoning. I know how to do it ~the hard way~.

Suppose we have the following set of data:

1) The first step in creating a box-and-whisker plot is **ordering** your data set:

2) Second, we need to find the **median** value: as we have **second quartile point** :

3) Third, we need to find the **other two quartile points** ,

For the first subset

For the second subset

4) Fourth, we'll **mark the 5 significant values** on a scale:

- the
**minimum and maximum**values:#3.9# and#5.2# - the
**quartiles**:#Q_1, Q_2 and Q_3# #4.2, 4.5 and 4.75#

5) Fifth, we **draw the box** , which goes from

6) Sixth, we **draw the whiskers** at the endpoints (minimum and maximum values

In the end, we'll get something like this:
