Explanation:
Sorting it in order: 7, 8, 9, 10, 11, 12, 13
To find the median: Look for the middle number. In this case, the middle number is 10.
To find the 1st quartile: The first quartile is the median of the first half of the data. So, the first half of the data is 7, 8, 9. The median is 8.
To find the 3rd quartile: The third quartile is like the 1st quartile, but it's on the other end. So, it contains 11, 12, 13. The median of that is 12.
To find the maximum: The maximum is the largest number in the data set. So, in this case, it is 13.
To find the minimum: The minimum is the smallest number in the data set. In this case, it is 7.
Data in all: median: 10 1st Quartile: 8 3rd Quartile: 12 Min: 7 Max: 13
