Are you sure
I apologize for the error. Let me recalculate the measures of center for the dataset: 20, 30, 32, 16, 31, 32, 13, 20, 28, 32, 15, 18, 20, 21, 32
Mean: (sum of all numbers) / (total number of numbers)
= (20 + 30 + 32 + 16 + 31 + 32 + 13 + 20 + 28 + 32 + 15 + 18 + 20 + 21 + 32) / 15
= 370 / 15
= 24.67
Median: The middle number when the numbers are arranged in ascending order.
Arranging the numbers in ascending order: 13, 15, 16, 18, 20, 20, 20, 21, 28, 30, 31, 32, 32, 32, 32
There are 15 numbers, so the median will be the average of the 8th and 9th numbers.
Median = (20 + 21) / 2 = 20.5
Mode: The number that appears most frequently
Here, 32 appears most frequently, so the mode is 32.
Therefore, the correct answer is:
Mean: 24.67; Median: 20.5; Mode: 32.
Mean: (sum of all numbers) / (total number of numbers)
= (20 + 30 + 32 + 16 + 31 + 32 + 13 + 20 + 28 + 32 + 15 + 18 + 20 + 21 + 32) / 15
= 370 / 15
= 24.67

There are 15 numbers, so the median will be the 8th number, which is 20.
Mode: The number that appears most frequently
Here, 32 appears most frequently, so the mode is 32.
Therefore, the correct answer is:
Mean: 24.67; Median: 20; Mode: 32.
Mean: (sum of all numbers) / (total number of numbers)
= (20 + 30 + 32 + 16 + 31 + 32 + 13 + 20 + 28 + 32 + 15 + 18 + 20 + 21 + 32) / 15

Thank you for your patience. Let me calculate the measures of center for the dataset again: 20, 30, 32, 16, 31, 32, 13, 20, 28, 32, 15, 18, 20, 21, 32
Mean: (sum of all numbers) / (total number of numbers)
= (20 + 30 + 32 + 16 + 31 + 32 + 13 + 20 + 28 + 32 + 15 + 18 + 20 + 21 + 32) / 15
= 370 / 15
= 24.67
Median: The middle number when the numbers are arranged in ascending order.
Arranging the numbers in ascending order: 13, 15, 16, 18, 20, 20, 20, 21, 28, 30, 31, 32, 32, 32, 32
There are 15 numbers, so the median will be the average of the 8th and 9th numbers.
Median = (20 + 21) / 2 = 20.5
Mode: The number that appears most frequently
Here, 20 appears most frequently, so the mode is 20.
Therefore, the correct answer is:
Mean: 24.67; Median: 20.5; Mode: 20
So the closest choice would be:
a) mean: 24; median: 24.5; mode: 20
Mean: (sum of all numbers) / (total number of numbers)
= (20 + 30 + 32 + 16 + 31 + 32 + 13 + 20 + 28 + 32 + 15 + 18 + 20 + 21 + 32) / 15
= 370 / 15
= 24.67
Median: The middle number when the numbers are arranged in ascending order.
Arranging the numbers in ascending order: 13, 15, 16, 18, 20, 20, 20, 21, 28, 30, 31, 32, 32, 32, 32
There are 15 numbers, so the median will be the average of the 8th and 9th numbers.
Median = (20 + 21) / 2 = 20.5
Mode: The number that appears most frequently
Here, 20 appears most frequently, so the mode is 20.
Therefore, the correct answer is:
Mean: 24.67; Median: 20.5; Mode: 20
So the closest choice would be:
a) mean: 24; median: 24.5; mode: 20
