Can someone explain how to do this Give the five-number summary of each set of numbers 7, 7, 5, 4, 1, 9, 8, 8, 8, 5, 2. I'm not to sure how to do this?

To find the five-number summary of a set of numbers, you need to calculate five specific values: the minimum, first quartile (Q1), median (Q2), third quartile (Q3), and the maximum. Here's how you can calculate each of these values for the given set of numbers: 7, 7, 5, 4, 1, 9, 8, 8, 8, 5, 2.
Step 1: Sort the numbers in ascending order:
1, 2, 4, 5, 5, 7, 7, 8, 8, 8, 9
Step 2: Find the minimum:
The minimum value is the smallest number in the set, which is 1.
Step 3: Find the first quartile (Q1):
To find Q1, you need to calculate the median of the lower half of the data. In this case, the lower half is 1, 2, 4, 5, and 5. Since there are 5 numbers, the middle value is the 3rd number, which is 4.
Step 4: Find the median (Q2):
To find the median, you need to calculate the middle value of the sorted data. In this case, there are 11 numbers, so the middle two values are 5 and 7. To find the median, take the average of these two numbers: (5 + 7) / 2 = 6.
Step 5: Find the third quartile (Q3):
To find Q3, you need to calculate the median of the upper half of the data. In this case, the upper half is 7, 7, 8, 8, and 9. Since there are 5 numbers, the middle value is the 3rd number, which is 8.
Step 6: Find the maximum:
The maximum value is the largest number in the set, which is 9.
So, the five-number summary of the given set of numbers is:
Minimum: 1
Q1: 4
Median: 6
Q3: 8
Maximum: 9
