Session 2, Part D:
The Median

In This Part: From Ordered Lists and Line Plots | From Cumulative Frequency Tables

You can also use a cumulative frequency table to find the median of the raisin count:

Raisin Count

Cumulative Frequency

25

1

26

3

27

6

28

11

29

15

30

16

31

17

The first position contains raisin count 25, the third position contains count 26, and so on.


 

Problem D5

Solution  

According to the cumulative frequency table, what count is in the second position?


 

Problem D6

Solution  

The sixth position corresponds to a box containing 27 raisins. How many raisins are in the boxes in the fourth and fifth positions?


Stop!  Do the above problem before you proceed.  Use the tip text to help you solve the problem if you get stuck.
How many raisins are in the third position? Why can't this be the same as the number of raisins in the fourth position?   Close Tip

 

Problem D7

Solution  

How would you use the cumulative frequency table to find the median?


Stop!  Do the above problem before you proceed.  Use the tip text to help you solve the problem if you get stuck.
First find the position in which the median is located (see Problem D1). Then look for the corresponding number on the table.   Close Tip
