Mean, Median, Mode, and Range

Front

What is the mean of a set of numbers?

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 median of a set of numbers?

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 the mode of a set of numbers?

Back

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

Front

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

Back

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

Front

If the numbers are 2, 4, 4, 6, 8, what is the mode?

Back

The mode is 4, as it appears most frequently.

Front

What is the median of the following set: 10, 20, 30, 40, 50?

Back

The median is 30, as it is the middle number in the ordered set.

Front

Calculate the mean of these numbers: 5, 10, 15, 20.

Back

The mean is (5 + 10 + 15 + 20) / 4 = 12.5.

Front

What is the range of the following scores: 100, 90, 80, 70, 60?

Back

The range is 100 - 60 = 40.

Front

If the set of numbers is 1, 2, 2, 3, 4, what is the mode?

Back

The mode is 2, as it appears most frequently.

Front

How do you find the median of the numbers: 3, 1, 4, 2?

Back

First, arrange them in order: 1, 2, 3, 4. The median is (2 + 3) / 2 = 2.5.
