pencil, red pen, highlighter, notebook, graphing calculator The following scores where earned on a test: 75, 82, 85, 74, 66, 64, 95, 30, 61, 81, 96, 95, 53, 64, 79, 44 a) Make a sorted list. b) Compute the mean, median, and mode. (You can use your calculator, but show your work!) c) Identify the 5 number summary. d) Compute the IQR and 1. 5 IQR. e) Use the 1. 5 IQR criterion, determine the cut off for lower and upper outliers. Identify any outliers. f) Make a modified box–and–whiskers plot.

c) Identify the 5 number summary. 30 ______, Min 62. 5 83. 5 74. 5 ______, Q 1 Med (Q 2) Q 3 96 ______ Max d) Compute the IQR and 1. 5 IQR = Q 3 – Q 1 1. 5 IQR = 1. 5 (21) IQR = 83. 5 – 62. 5 = 31. 5 IQR = 21 e) Use the 1. 5 IQR criterion, determine the cut off for lower and upper outliers. Identify any outliers. lower bound = Q 1 – 1. 5 IQR = 62. 5 – 31. 5 = 31 30 is an outlier. Upper bound = Q 3 + 1. 5 IQR = 83. 5 + 31. 5 = 115 No upper outliers.
f) Make a modified box–and–whiskers plot. 30 20 30 44 40 62. 5 Q 1 50 60 74. 5 83. 5 Med Q 3 70 80 96 90 100 scores
