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
I don't need an answer just want to know how do I compare the ages with mean and median? Really confused
me too ugh
To compare the ages of the patients of doctor 1 and doctor 2 using the mean and the median, you will need to compute the mean and median of each dataset separately. Here's how to do it:
Mean:
1. Identify the dataset for each doctor (in this case, Doctor 1 and Doctor 2).
2. Calculate the sum of all the ages in each dataset.
3. Divide the sum by the total number of ages in each dataset to find the mean.
Median:
1. Arrange the ages in each dataset in ascending order.
2. Find the middle value of the sorted dataset. If there is an odd number of ages, the median will be the middle value. If there is an even number of ages, the median will be the average of the two middle values.
Once you have calculated the mean and median for each dataset, you can compare them to determine the differences between the ages of the patients seen by each doctor.
