Short answer
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
dude that doesnt help at all, it's a short answer question not multiple choice
can someone answer this ?
To compare the ages of the patients of doctor 1 and doctor 2 using the mean and the median, you can follow these steps:
1. Find the mean for each data set:
- For doctor 1: To find the mean, add up all the ages in doctor 1's data set and divide it by the total number of ages. Then round the result to the nearest whole number.
- For doctor 2: Similarly, add up all the ages in doctor 2's data set and divide it by the total number of ages. Round the result to the nearest whole number.
2. Find the median for each data set:
- For doctor 1: To find the median, arrange the ages from doctor 1's data set in ascending order. If there is an odd number of ages, the median is the middle value. If there is an even number of ages, the median is the average of the two middle values.
- For doctor 2: Similarly, arrange the ages from doctor 2's data set in ascending order and find the median using the same process as above.
By comparing the mean and median of each data set, you can determine how the ages of the patients seen by doctor 1 and doctor 2 differ in terms of the central tendency.
