Lesson 2

Five Number Summary:

identifies the following KEY values in a data set

First, put the data in order:

Lowest Value (Mininum):

a graph that displays the five number summary. To create a box plot:

Box Plots:

Lower Quartile (1st Quartile):

6.5

1) Find each value from the five number summary on the number line below and place a tick mark above that number

2) Draw a box around the 3 middle tick marks (with the edges of the box being the quartiles)

Median (halfway or 2nd Quartile):

10

3) Draw a 'whiskers' (horizontal lines) from the edges of the box out to the lowest and highest values.

Upper Quartile (3rd Quartile):

14

Highest Value (Maximum):

17
