Mean, Median, Mode, and Range

Front

What is the definition of Mean in statistics?

Back

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 calculate the Median of a data set?

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 Mode in statistics?

Back

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

Front

What is the Range of a set of numbers?

Back

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

Front

Calculate the Mean of the following numbers: 1, 2, 3, 4, 5.

Back

Mean = (1 + 2 + 3 + 4 + 5) / 5 = 3.

Front

Find the Median of the following numbers: 3, 1, 4, 2, 5.

Back

Median = 3 (after arranging the numbers: 1, 2, 3, 4, 5).

Front

What is the Mode of the following numbers: 2, 3, 4, 2, 5?

Back

Mode = 2 (it appears most frequently).

Front

What is the Range of the following numbers: 10, 15, 20, 5?

Back

Range = 20 - 5 = 15.

Front

If the data set is 4, 4, 7, what is the Median?

Back

Median = 4 (the middle number in the ordered set).

Front

How do you find the Median if there are two middle numbers?

Back

Add the two middle numbers together and divide by 2.
