Mean, Median, Mode, MAD

Front

What is the MODE of a set of numbers?

Back

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

Front

How do you calculate the MEAN of a set of numbers?

Back

Add all the numbers together and then divide by the total count of numbers.

Front

What does MEDIAN represent in a data set?

Back

The MEDIAN is the middle value when the numbers are arranged in order.

Front

What is the definition of Mean Absolute Deviation (MAD)?

Back

MAD is a measure of the average distance between each data point and the mean of the data set.

Front

Find the MODE of the following data: 90, 85, 90, 95.

Back

90

Front

Calculate the MEAN of the following wins: 89, 103, 95, 97, 95, 85, 84, 87, 84.

Back

91

Front

What is the formula for calculating the MEDIAN?

Back

Arrange the numbers in order and find the middle value. If there are two middle values, average them.

Front

If the MEAN of a data set is 8.2, what is the Mean Absolute Deviation if the values are 5, 11, 2, 7, 16?

Back

4.2

Front

What is the difference between MEAN and MEDIAN?

Back

MEAN is the average of all numbers, while MEDIAN is the middle value.

Front

How do you find the Mean Absolute Deviation?

Back

1. Find the mean. 2. Subtract the mean from each data point and take the absolute value. 3. Find the mean of those absolute values.
