find correct set of data

Question

Stem/ leaf

1/13

2/268

3/18

Answer 1

A stem and leaf display shows the values in a data set by groupings.  In this case the groupings are each ranges of 10. 

 

1/ includes the values that are 2-digit numbers where the first digit is 1, so that would be numbers from 10 through 19.  The values after the slash are the second digit of the number.

 

So 1/13 means that there are 2 numbers in the group, 11 and 13.

 

Following this for all three groups, you see that the original values are:

 

11

13

22

26

28

31

38
