Mean, Median, Mode, Range

Front

What is the mean of a data set?

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

What is the median of a data set?

Back

The median is the middle value of a data set when the numbers are arranged in order. 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 data set?

Back

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

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 data set: 5, 10, 15, 20, 25.

Back

Mean = (5 + 10 + 15 + 20 + 25) / 5 = 15.

Front

Calculate the median of the data set: 3, 1, 4, 2, 5.

Back

Median = 3 (when arranged in order: 1, 2, 3, 4, 5).

Front

Calculate the mode of the data set: 2, 3, 4, 2, 5, 2, 3.

Back

Mode = 2 (it appears most frequently).

Front

Calculate the range of the data set: 8, 3, 7, 5, 10.

Back

Range = 10 - 3 = 7.

Front

What is a data set?

Back

A data set is a collection of numbers or values that can be analyzed to find patterns or insights.

Front

How do you find the median in an even set of numbers?

Back

Arrange the numbers in order, find the two middle numbers, and calculate their average.
