Mean, Median, and Mode

What is the median of the following numbers: 8, 3, 7, 5, 6?

• 5

• 6

• 7

• 8

What is the median of the set: 7, 9, 5, 6, 8?

• 5

• 6

• 7

• 8

How do you calculate the mean of a data set?

• Add all the numbers together and divide by the total count of numbers.

• Multiply all the numbers together and divide by the total count of numbers.

• Add the largest and smallest numbers and divide by two.

• Subtract the smallest number from the largest number.

Calculate the mean of the following set: 10, 20, 30, 40, 50.

• 25

• 30

• 35

• 40

What is the mode?

• The average of a data set.

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

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

• The highest value in a data set.

What is the median of the following set: 12, 15, 10, 14, 13?

• 12

• 13

• 14

• 15

Find the median of this set: 3, 1, 4, 2, 5.

• 2

• 3

• 4

• 1

Determine the mode of the following numbers: 2, 3, 4, 2, 5, 3, 2.

• 2 (it appears most frequently)

• 3 (it appears most frequently)

• 4 (it appears most frequently)

• 5 (it appears most frequently)

How do you find the median?

• Arrange the numbers in order and identify the middle number. If there is an even number of values, the median is the average of the two middle numbers.

• Add all the numbers together and divide by the total count.

• Select the largest number in the dataset as the median.

• Choose the smallest number in the dataset as the median.
