the following dot plot shows how far peter ran in each of his tennis matches this year. distance ran in each match 1 2 3 4 5 6 7 distance (kilometers) find the median distance. km
Answer
Explanation:
Step1: Count the number of data - points
There are 1 + 2+ 4+ 2 = 9 data - points.
Step2: Determine the position of the median
For a set of (n) data - points, when (n) is odd, the median is the (\left(\frac{n + 1}{2}\right))-th value. Here (n=9), and (\frac{9 + 1}{2}=5)-th value.
Step3: Arrange the data in ascending order
The data set in ascending order (based on the dot - plot) is: 3, 4, 4, 5, 5, 5, 5, 7, 7. The 5 - th value is 5.
