Mean Median Mode and Range

How do you calculate the range of a data set?

• To calculate the range, subtract the smallest number from the largest number in the data set.

• To calculate the range, add the smallest number to the largest number in the data set.

• To calculate the range, multiply the smallest number by the largest number in the data set.

• To calculate the range, divide the largest number by the smallest number in the data set.

What is the median of an odd set of numbers?

• The average of all the numbers in the set.

• The middle number when the numbers are sorted.

• The largest number in the set.

• The smallest number in the set.

What is the mode of 2, 2, 2, 4, 4, 5, 6, 6, 6, 7?

• 2

• 4

• 6

• 2 and 6

What is the mode?

• The mode is the average of a data set.

• The mode is the number that appears most frequently in a data set.

• The mode is the middle value in a data set when arranged in order.

• The mode is the largest number in a data set.

What happens to the mean if you add a very large number to a data set?

• The mean remains unchanged.

• The mean decreases significantly.

• Adding a very large number will increase the mean, as it raises the total sum of the numbers.

• The mean becomes zero.

What is the median?

• The median is the average of all numbers in a list.

• The median is the middle number in a sorted list of numbers.

• The median is the largest number in a list.

• The median is the smallest number in a list.

What is the first step to find the median?

• Sort the numbers in ascending order.

• Calculate the mean of the numbers.

• Identify the mode of the numbers.

• Count the total number of values.

How do you find the median of 1, 2, 2, 8, 9, 14?

• 4

• 5

• 6

• 7

If a data set has no repeating numbers, what can you say about the mode?

• The mode is the highest number in the data set.

• The mode is the average of the data set.

• The data set has no mode.

• The mode is the most frequently occurring number.

How do you find the mean of 2, 57, 38, 42, 6?

• Add the numbers and divide by 5: 29

• Multiply the numbers and divide by 5: 145

• Add the numbers and divide by 4: 36.25
