\fa) Write a frequency table that captures all the information from the histogram, then use it as needed to calculate the following: mean (M), mean absolute deviation (MAD), mean squared deviation (MSD), sample variance (s2), sample standard deviation (s). Bin Lower Upper Midpoint Freq (i) Bound Bound (Mi) ( fi ) 1 79 81 80 2 2 81 83 82 2b) Find the median, upper and lower quartiles, then draw the boxplot (by hand) [You can continue to use the table above, or draw a new one.] c) If we doubled each value, how would each of the statistics you calculated change? d) What if instead we added the number 10 to each value?
