1. From the pressure data below, make a dot diagram. Mark the location of the mean
and standard deviation. (You can use Excel or MATLAB to do this by plotting x-y
data where all of the y points are 0. Minitab and R can also do this.)
a. 25 28 29 35 37 37 42 44 45 47 49 56 87 91
2. Using the data from the strength of material tests below, find the mean, median,
and standard deviation of the data set. Make the following types of plots.
a. Stem-and-leaf diagram
b. Histogram (bins of your choosing)
c. Box plot
See the attached file for data.
