The mean absolute deviation, or MAD, and the interquartile range, or IQR, are measures of variability. Measures of variability tell you how much the values in a data set tend to differ while a smaller measure of variability means that the data is more consistent and close to from one another. A greater measure of variability means that the data is more spread out Are you ready for more? LFind possible locations for the 6 pennies, Les Lesson 5 Summary the measure of center. To calculate the MAD of a data set: 1. Find the mean of the values in the data set. 2. Find the distance between each data value and the mean on the number line: |data value - mean| 3. Find the mean of the distances. This value is the MAD. To calculate the IQR, subtract the value of the first quartile from the value of the third quartile. Recall that the first and third quartile are included in the five number summary. 38 Student Workbook Algebra

Mai collects information about 37 classmates. She believes her data set is perfectly symmetrical with a mean and median of 20. She then realizes that the number she has recorded as 32 was actually supposed to be 42. What is true about the mean and median of her corrected data set? A: The mean and median of the corrected set are both still 20. B: The mean of the corrected data set is still 20, but the median is greater than 20. C: The median of the corrected data set is still 20, but the mean is greater than 20. D: The mean and median of the corrected set are both greater than 20.
In this problem, we explore the effect on the mean, median, and mode of adding the same number to each data value. Consider the data set 2, 2, 3, 6, 10. (a) Compute the mode, median, and mean. (Enter your answers to one decimal place.)mode median mean (b) Add 7 to each of the data values. Compute the mode, median, and mean. (Enter your answers to one decimal place.)mode median mean (c) Compare the results of parts (a) and (b). In general, how do you think the mode, median, and mean are affected when the same constant is added to each data value in a set? -Adding the same constant c to each data value results in the mode, median, and mean decreasing by c units. -Adding the same constant c to each data value results in the mode, median, and mean remaining the same. -Adding the same constant c to each data value results in the mode, median, and mean increasing by c units. -There is no distinct pattern when the same constant is added to each data value in a set.
