- What is the mean?
- What is the median?
- What is the mode?
- What is the standard deviation?
- Create a Bar Graph for each of the 2 out of the 3 questions. What type of skewness is present, if any?
- Are there any outliers? If so, what are the outliers? Do you believe they were typos?
- What is the range and midrange?

a. Less than 2.16
b. Greater than 1.66
c. Between 1.2 and 1.9
