The back-to-back stem-and-leaf plot below shows the ages of patients seen by two doctors in a family clinic in one day. Compare the ages of the patients of doctor 1 and doctor 2 using the mean and the median of each data set.
Doctor 1 Doctor 2
| 3 | 5
9 2 0 | 2 | 0 0 2 3 6
8 7 5 | 1 | 3 7
9 7 3 2 1 1| 0 | 2 2 3 9
Key: means 29 9|2|3 means 23
Can someone explain this.......
Embershy is right, but you when you add all the number together you divide that number by how many numbers there are in the data set,
1, 1, 2, 3, 7, 9, 15, 17, 18, 20, 22, 29 = 144/12 = 12
35, 20, 20, 22, 23, 26, 13, 17, 2, 2, 3, 9 = 192, 192/12 = 16
So the mean for Doctor 1 is '12' and the mean for Doctor 2 '16'
