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 observations, 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

How do you find the Range of a set of numbers?

Back

The range is calculated by subtracting the smallest number from the largest number in the set.

Front

Find the Mean of the following numbers: 10, 20, 30, 40, 50.

Back

Mean = (10 + 20 + 30 + 40 + 50) / 5 = 30.

Front

Find the Median of the following numbers: 3, 1, 4, 2, 5.

Back

Median = 3 (after arranging: 1, 2, 3, 4, 5).

Front

What is the Mode of the following numbers: 1, 2, 2, 3, 4?

Back

Mode = 2 (it appears most frequently).

Front

Calculate the Range of the following numbers: 5, 10, 15, 20, 25.

Back

Range = 25 - 5 = 20.

Front

Find the Mean of these scores: 85, 90, 75, 80, 95.

Back

Mean = (85 + 90 + 75 + 80 + 95) / 5 = 85.

Front

What is the Median of the following set: 8, 3, 7, 5, 9?

Back

Median = 7 (after arranging: 3, 5, 7, 8, 9).
