To find the median of a set of numbers, follow these steps:
1. Arrange the numbers in ascending order:
17, 21, 22, 22, 26, 30, 38, 59, 67, 85.
2. Determine if the number of values is odd or even. In this case, there are 10 numbers, which is even.
3. Since there is an even number of values, find the two middle numbers and calculate their average.
The fifth number is 26, and the sixth number is 30.
Median = (26 + 30) / 2 = 56 / 2 = 28.
Therefore, the median of the set 26, 30, 38, 67, 59, 21, 17, 85, 22, 22 is 28.
To find the five-number summary of a set of numbers, follow these steps:
1. Arrange the numbers in ascending order:
1, 2, 4, 5, 5, 7, 7, 8, 8, 8, 9.
2. Find the minimum value, which is 1.
3. Find the first quartile (Q1), which is the median of the lower half of the dataset. Since the dataset has 11 values, the lower half has 5 values. The fifth value is 5.
4. Find the median, which we found earlier as 5.
5. Find the third quartile (Q3), which is the median of the upper half of the dataset. The sixth value (out of the 11 values) is 7.
6. Find the maximum value, which is 9.
Therefore, the five-number summary of the set 7, 7, 5, 4, 1, 9, 8, 8, 8, 5, 2 is minimum: 1, Q1: 5, median: 5, Q3: 7, maximum: 9.
To find the range of a set of numbers, follow these steps:
1. Arrange the numbers in either ascending or descending order:
1, 2, 4, 5, 5, 7, 7, 8, 8, 8, 9.
2. Subtract the minimum value from the maximum value.
Range = Maximum value - Minimum value
Range = 9 - 1 = 8.
Therefore, the range of the set 7, 7, 5, 4, 1, 9, 8, 8, 8, 5, 2 is 8.
