Mean, Median, Mode & Range

Front

What is the 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 mean of the numbers 1, 0, 1, 5, 6, 3, 4?

Back

Add the numbers: 1 + 0 + 1 + 5 + 6 + 3 + 4 = 20. Divide by the count (7): 20 / 7 = 2.85.

Front

What is the median?

Back

The median is the middle value in a list of numbers sorted in ascending order. If there is an even number of values, the median is the average of the two middle numbers.

Front

How do you find the median of the numbers 58, 60, 62, 66?

Back

Sort the numbers: 58, 60, 62, 66. The median is the average of 60 and 62: (60 + 62) / 2 = 61.

Front

What is the mode?

Back

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

Front

Find the mode of the numbers 12, 10, 10, 10, 13, 12, 11, 13, 10.

Back

The mode is 10, as it appears most frequently.

Front

What is the range?

Back

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

Front

Calculate the range of the numbers 1, 0, 1, 5, 6, 3, 4.

Back

Range = highest value (6) - lowest value (0) = 6.

Front

What is the formula for calculating the mean?

Back

Mean = (Sum of all values) / (Number of values).

Front

How do you find the mean of the numbers 28, 18, 19, 18, 17?

Back

Add the numbers: 28 + 18 + 19 + 18 + 17 = 100. Divide by the count (5): 100 / 5 = 20.
