Mean Absolute Deviation Quiz

What is the formula for calculating mean absolute deviation?

• Mean absolute deviation is calculated by finding the absolute difference between each data point and the mean, then calculating the average of these absolute differences.

• Mean absolute deviation is calculated by finding the absolute difference between each data point and the range, then calculating the average of these absolute differences.

• Mean absolute deviation is calculated by finding the absolute difference between each data point and the mode, then calculating the average of these absolute differences.

• Mean absolute deviation is calculated by finding the absolute difference between each data point and the median, then calculating the average of these absolute differences.

Calculate the mean absolute deviation for the following set of numbers: 5, 8, 10, 12, 15.

• 6.1

In a real-life scenario, how can mean absolute deviation be used to compare the performance of two different products?

• By calculating the standard deviation and comparing the values for each product.

• By calculating the mean absolute deviation and comparing the values for each product.

• By calculating the median absolute deviation and comparing the values for each product.

• By calculating the range and comparing the values for each product.
