Mean, Median, Mode, and 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 total count of numbers.

Front

How do you calculate the mean of the numbers 1, 0, 1, 5, 6, 3, 4?

Back

Add all the numbers: 1 + 0 + 1 + 5 + 6 + 3 + 4 = 20. Then divide by the count of numbers (7): 20 ÷ 7 = 2.85.

Front

What is the median?

Back

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

Front

Find the median of these numbers: 4, 2, 7, 4, 3.

Back

First, sort the numbers: 2, 3, 4, 4, 7. The median is 4.

Front

What is mode?

Back

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

Front

What is the mode of the numbers 1, 2, 2, 3, 4?

Back

The mode is 2, as it appears most frequently.

Front

What is the range?

Back

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

Front

Calculate the range of the scores: 155, 165, 138, 172, 127, 193, 142.

Back

The highest score is 193 and the lowest is 127. Range = 193 - 127 = 66.

Front

What is the range of the heights: 1.83m, 1.55m, 1.76m, 1.52m, 1.81m, 1.70m, 1.85m, 1.91m?

Back

The highest height is 1.91m and the lowest is 1.52m. Range = 1.91 - 1.52 = 0.39m.

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

Back

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