Mean, Median, Mode, + Range

Front

What is the definition of Mean in statistics?

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 in statistics?

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 of the following numbers: 10, 20, 30.

Back

Mean = (10 + 20 + 30) / 3 = 20.

Front

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

Back

Arrange in order: 1, 2, 3, 4. Median = (2 + 3) / 2 = 2.5.

Front

Identify the Mode of the following numbers: 5, 1, 5, 3, 2.

Back

Mode = 5 (it appears most frequently).

Front

What is the formula for calculating the Range?

Back

Range = Maximum value - Minimum value.

Front

Calculate the Mean of the following test scores: 70, 80, 90, 100.

Back

Mean = (70 + 80 + 90 + 100) / 4 = 85.

Front

Find the Median of the following set of numbers: 8, 3, 7, 5, 10.

Back

Arrange in order: 3, 5, 7, 8, 10. Median = 7.
