Mean, Median, Mode, and Range Practice

Front

What is the definition of Mean in statistics?

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 find the Median of a set of numbers?

Back

To find the Median, arrange the numbers in order from least to greatest. If there is an odd number of values, the Median is 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 definition of Mode in statistics?

Back

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

Front

What is the Range of a set of numbers?

Back

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

Front

How do you calculate the Mean of the following numbers: 9, 8, 12, 6, 10?

Back

Add the numbers: 9 + 8 + 12 + 6 + 10 = 45. Then divide by the count of numbers (5): 45 / 5 = 9.

Front

What is the Median of the following set of numbers: 15, 22, 16, 24, 16, 20, 12, 27?

Back

First, arrange the numbers: 12, 15, 16, 16, 20, 22, 24, 27. There are 8 numbers (even), so the Median is the average of the 4th and 5th numbers: (16 + 20) / 2 = 18.

Front

If a data set has no repeating numbers, what can you say about the Mode?

Back

If there are no repeating numbers in a data set, it has no Mode.

Front

How do you find the Range of the following numbers: 28, 18, 19, 18, 17?

Back

The highest number is 28 and the lowest is 17. The Range is 28 - 17 = 11.

Front

What is the Mean of the following numbers: 1, 0, 1, 5, 6, 3, 4?

Back

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

Front

What is the Median of the following numbers: 28, 18, 19, 18, 17?

Back

First, arrange the numbers: 17, 18, 18, 19, 28. The Median is the middle number, which is 18.
