Mean, Median, Mode, 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 in a set of numbers?

Back

The mode is the number that appears most frequently in a data set. A set may have one mode, more than one mode, or no mode at all.

Front

Define the range of a set of numbers.

Back

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

Front

Calculate the mean of the following numbers: 4, 5, 6, 7.

Back

Mean = (4 + 5 + 6 + 7) / 4 = 5.5.

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

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

Back

The mode is 2, as it appears most frequently.

Front

Determine the range of the following numbers: 10, 15, 20, 5.

Back

Range = 20 - 5 = 15.

Front

If a data set has no repeating numbers, what can be said about its mode?

Back

The data set has no mode.

Front

How do you find the mean of a data set with an even number of values?

Back

Add all the values together and divide by the total number of values.
