Final answer:
To calculate the mean, add all the numbers and divide by their count. The median is the middle number after sorting the data set. The mode is the most frequently occurring number and the range is the difference between the highest and lowest values.
Step-by-step explanation:
The student has asked to find the mean, median, mode, and range for the following data set: 72, 43, 15, 66, 32, 72, 52, 19, 28, 81.
Steps to find the mean:
Add all the numbers together.
Divide the sum by the total count of numbers.
Steps to find the median:
Arrange the numbers in ascending order.
Find the middle number or the average of the two middle numbers.
Steps to find the mode:
Identify the number that appears most frequently in the data set.
Steps to find the range:
Identify the maximum and minimum values in the data set.
Subtract the minimum value from the maximum value.
To answer the student's question:
The mean is found by adding all numbers and dividing by the count of numbers.
The median is the middle value once the numbers are sorted in order.
The mode is the number that occurs most often.
The range is the difference between the highest and lowest values.
