Find the descriptive statistics and create a box plot using the given data 1, 1, 2, 3, 4, 5, 7, 8, 9, 9, 12 a. Minimum = __________ b. Quartile 1 = __________ c. Median = __________ d. Quartile 3 = __________ e. Maximum = __________ f. Mean = __________ g. Interquartile Range = __________ h. Lower Inner Fence = __________ i. Upper Inner Fence = __________ Box Plot ©2016 Pamela Hrabal Graphical Displays 2. Create a Bar Chart and Dot Plot to organize the following data. A statistics class took a survey of 100 people about favorite automobile maker. The results came back that 30 favored Ford, 25 favored Chevy, 13 favored Nissan, 12 favored Toyota, and the rest favored βotherβ. Bar Chart Dot Plot ©2016 Pamela Hrabal Graphical Displays 3. Below are test scores for 20 AP Statistics students.
