Mean, Median, Mode & Range

Front

What is the definition of Mean?

Back

The mean is the average of a set of numbers, calculated by adding all the numbers together and dividing by the count of numbers.

Front

How do you calculate the Median?

Back

To find the median, arrange the numbers in ascending order and identify the middle number. If there is an even number of values, the median is the average of the two middle numbers.

Front

What is Mode?

Back

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

Front

What is the Range of a data set?

Back

The range is the difference between the highest and lowest values in a data set.

Front

Calculate the Mean: 5, 10, 15, 20

Back

Mean = (5 + 10 + 15 + 20) / 4 = 12.5

Front

Find the Median: 3, 1, 4, 2

Back

Median = 2.5 (arranged: 1, 2, 3, 4; average of 2 and 3)

Front

Determine the Mode: 7, 8, 8, 9, 10

Back

Mode = 8 (it appears most frequently)

Front

What is the formula for calculating Range?

Back

Range = Maximum value - Minimum value.

Front

Calculate the Mean: 12, 14, 16, 18, 20

Back

Mean = (12 + 14 + 16 + 18 + 20) / 5 = 16

Front

Find the Median: 8, 3, 5, 7, 9

Back

Median = 7 (arranged: 3, 5, 7, 8, 9)
