Class Assignment # 1 – Math 136 – Summer 2021 1. The side-by-side boxplots below shows the number of books read by students in 2 different classes throughout a semester. a) Using the above graph, approximate the bottom 25% of books read by Class B students. b) Write down the 5-number summary for Class B students. c) Check for outliers by computing both the lower and upper fences for Class B students. Are there any outliers? Justify your reasoning! d) Which class has less spread (dispersion) in number of books read? Give a sound statistical justification for your reasoning! e) What type of data is visualized in the above side-by-side boxplots? f) Describe the shape, center, and spread for Class B boxplot only. 2. Below are two graphs visualizing the same data. The visualized data represents the length of film (minutes). Class A Class B Graph A Graph B a) What is Graph A called? b) What is Graph B called? c) Describe the shape of Graph A. d) What is the class width of Graph A? e) What is the mode of Graph A? f) What is the mode of Graph B? g) Enter the above data from Graph B into StatCrunch. Then compute the range, standard deviation, and IQR (interquartile range). Save your data set in StatCrunch (Click on Data, then select Save). Once you have calculated the summary statistics with StatCrunch, take a screenshot of your work and upload your screenshot with your Class Assignment # 1. h) Which measure of spread is better to use for the above data set? Justify your reasoning!
