Mean Absolute Deviation MAD | 6.SP.3

The video tutorial introduces the concept of Mean Absolute Deviation (MAD), explaining its components: mean, absolute value, and deviation. It demonstrates how to calculate the mean from a set of survey data and then uses this to find the MAD, illustrating the process with a dot plot. The tutorial emphasizes the significance of MAD in understanding data spread and variability, providing a practical example of its application. The lesson concludes by highlighting the value of MAD in interpreting real-world data.

What does the term 'absolute' refer to in the context of Mean Absolute Deviation?

• The average of data points

• The distance of a value from zero

• The most frequent value in a data set

• The distance of a value from the mean

In the survey data, what is the mode of the number of hours students spend studying per week?

• 10 hours

• 6 hours

• 4 hours

• 2 hours

How is the mean of a data set calculated?

• By adding all values and dividing by the number of values

• By finding the most frequent value

• By finding the middle value when data is ordered

• By subtracting the smallest value from the largest

What does a larger Mean Absolute Deviation (MAD) indicate about a data set?

• The data points are more spread out

• The data set has more frequent values

• The data points are closer to the mean

• The data set has a higher mean

Why is Mean Absolute Deviation (MAD) a valuable tool in data analysis?

• It calculates the total sum of data points

• It helps find the mode of the data set

• It determines the highest and lowest values

• It helps understand data consistency and variability
