Mean, Median, Mode, Range, and MAD

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 count of numbers.

Front

How do you find 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

What is the range of a set of numbers?

Back

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

Front

What does MAD stand for in statistics?

Back

MAD stands for Mean Absolute Deviation, which measures the average distance between each data point and the mean of the data set.

Front

Calculate the mean of the following set of numbers: 5, 10, 15, 20, 25.

Back

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

Front

Find the median of the following set of numbers: 3, 7, 9, 12, 15, 18.

Back

Median = (9 + 12) / 2 = 10.5 (since there are an even number of values).

Front

Identify the mode of the following set of numbers: 2, 4, 4, 6, 8, 8, 8, 10.

Back

Mode = 8 (it appears most frequently).

Front

Calculate the range of the following set of numbers: 10, 15, 20, 25, 30.

Back

Range = 30 - 10 = 20.

Front

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

Back

MAD = (|1-3| + |2-3| + |3-3| + |4-3| + |5-3|) / 5 = 1.2.
