Mean, Median, and Absolute Deviation

This video tutorial guides 6th-grade students through the process of finding the mean absolute deviation. It covers calculating the mean, determining the median, and understanding absolute deviation. The tutorial emphasizes attention to detail and provides step-by-step instructions for each part of the process, ensuring students can accurately compute these statistical measures.

What are the three main components needed to find the Mean Absolute Deviation?

• Mean, Mode, and Range

• Range, Mean, and Mode

• Mean, Median, and Absolute Deviation

• Median, Mode, and Standard Deviation

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

• Find the middle number in the set

• Add all numbers and divide by the number of numbers

• Subtract the smallest number from the largest

• Multiply all numbers together

• 52

• 58

• 54

• 56

How do you determine the median of a set of numbers?

• Add all numbers and divide by the number of numbers

• Find the middle number after ordering from least to greatest

• Subtract the smallest number from the largest

• Multiply all numbers together

What is the absolute deviation of a number in a set?

• The product of the number and the mean

• The sum of all numbers in the set

• The difference between the number and the mean

• The difference between the largest and smallest numbers
