follow the steps below for the following set of data. in your final answer include all of your calculations and all work in steps 1, 2, and 3.

8, 3, 5, 5, 4, 7

1. find the median, lower quartile, and upper quartile of the set of data.
2. use the median, lower quartile, upper quartile, lowest value, and highest value of the set to construct a box-and-whisker plot on your own sheet of paper.
3. use the box-and-whisker plot to find the range and the interquartile range of the set of data.

Step-by-step explanation:

put the numbers in order from lowest to highest

3,4,5,5,7,8

median (middle number) is : (5 + 5)/2 = 10/2 = 5

lower quartile : 4

upper quartile : 7

box and whisker plot :

     min         Q1            M             Q3      max

         3         4             5                7            8

 1|||9

ur gonna have to draw a box from Q1 to Q3 with a vertical line through the median. Draw a whisker from Q1 to the minimum and from Q3 to the maximum.

The interquartile range is the difference between Q3 and Q1

so the interquartile range is : Q3 - Q1 = 7 - 4 = 3

the range is the difference between the highest and lowest numbers in ur data set. So the range is : 8 - 3 = 5
