Explanation / Answer

Data set is 63,67,60,73,86,81,26,55,79,38,19,67,74,53,75,79,45,54,79,86,83,90,64,57,85,50,48,75,68,51,53,86,44

First step is arrange them in ascending order so that its easy to make the stem leaf plot

the arranged data is

19,26,38,44,45,48,50,51,53,53,54,55,57,60,63,64,67,67,68,73,74,75,75,79,79,79,81,83,85,86,86,86,90

Now,we make the stem leaf plot

1             9

2             6

3             8

4             4             5             8

5             0             1             3             3             4             5             7

6             0             3             4             7             7             8

7             3             4             5             5             9             9             9

8             1             3             5             6             6             6
