Multiple Choice
The range measures the width between the highest and lowest values in a data set. Which of these is the range for the data set shown below:
2, 5, 16, 18, 19, 100
5
Multiple Select
Q1, or Quartile 1, is the value that identifies the middle of the lower half. Q3, or Quartile 3, is the value that identifies the middle of the upper half. Which of the following is true based on the image shown? Choose ALL that apply.
6
Multiple Select
Which of the following is true based on the data set shown? Choose ALL that apply.
7
Multiple Choice

Multiple Select
An outlier is a value that is much smaller or much greater than other values in a data set.
An outlier can affect the mean, or average of a set of data by adding in a value that is extremely small or extremely high. Which of the following is true about outliers? Choose ALL that apply.
10
Multiple Select
We can identify outliers by setting boundaries.
1. multiply 1.5 x IQR to determine the stretcher.
2. Lower boundary = Q1 - stretcher
3. Upper boundary = Q3 + stretcher
Which of the following is true about outliers? Choose ALL that apply.

Multiple Select
Mean Absolute Deviation (M.A.D.) is the average distance between each value and the mean of a data set. Which of the following is true about M.A.D.? Choose ALL that apply.
12
Multiple Select
Steps for finding the M.A.D.:
1. find the mean or average
