Understanding Mode, Range, and Median

What is the mode of a set of numbers?

• The difference between the highest and lowest numbers

• The average of all the numbers

• The number that appears most frequently

• The middle number when all numbers are arranged in order

How do you calculate the range of a set of numbers?

• Add all the numbers together and divide by the number of numbers

• Subtract the smallest number from the largest number

• Find the number that appears most frequently

• Arrange the numbers in order and find the middle number

What is the median of the set of numbers 3, 7, 9, 5, and 2?

• 3

• 5

• 7

• 9

If a set of numbers has two modes, what is it called?

• Unimodal

• Bimodal

• Trimodal

• Multimodal

What is the range of the set of numbers 8, 3, 5, 10, and 2?

• 5

• 7

• 8

• 10

If all numbers in a set are the same, what is the median?

• There is no median

• The repeated number

• The sum of all numbers divided by the number of numbers

• The difference between the highest and lowest numbers

In a set of numbers, if there is no number that appears more than once, what is the mode?

• The set has no mode

• The highest number

• The lowest number

• The average of all numbers

How do you find the median in a set of an even number of numbers?

• There is no median for an even number of numbers

• Take the middle two numbers and divide their sum by two

• Choose the larger of the middle two numbers

• Choose the smaller of the middle two numbers

What does the range of a set of numbers tell you?

• How spread out the numbers are

• The average value of the numbers

• The most frequent number

• The middle value of the numbers

If the set of numbers is {4, 4, 4, 9, 10}, what is the mode?

• 4

• 9

• 10

• There is no mode
