Box And Whisker Plot

Its all about the medians! The test scores in this class were 36,24,55,89,98,101,75,85,92,92,89, and 100. Create a box and whisker plot for the data. First, Find the median Median is 89 24,36,55,75,85,89,89,92,92,98,100,101 89 101 24

24,36,55,75,85,89,89,92,92,98,100,101 (98+92)/2= 95 (55+75)/2= 65 101 89 95 24 65

89 95 101 65 24 http://www.explorelearning.com/index.cfm?method=cResource.dspDetail&ResourceID=169

Activity From the data gathered at the beginning of class, I will assign a topic to each group. Create a Box and Whisker Plot Create a Stem and Leaf Plot Display the measures of central tendency. Display to the class.
