Quantitative Data Analysis Exercise 1) For the following data ranging from 0-20, construct a histogram: 1 2 2 2 3 3 4 5 5 5 6 6 6 6 6 7 7 7 8 8 8 8 9 9 9 9 9 9 9 10 10 10 10 10 10 11 11 11 11 11 11 11 12 12 12 12 12 13 13 13 14 14 14 15 15 16 16 16 17 17 17 18 18 19 20

2) For the data set in Question 1, calculate the mean, median, mode, variance, and standard deviation. Consider the data set as a population when calculating variance and standard deviation.

3) For the following sample data set, calculate the mean, variance, and standard deviation: 158 191 132 184 166 142 185 196 174 188 185 174 163 152 141
