Construct a histogram for the data set. What is the mostappropriate measure of variation for this distribution and what isits value? Why did you use this measurement?
A) The variance is the most appropriate measure and it is equalto 229.51. I used the variance because the variance is the bestmeasure of variation regardless of the shape of thedistribution.
B) The standard deviation is the most appropriate measure and itis equal to 15.52. I used the standard deviation because the graphis skewed.
C) The interquartile range (IQR) is the most appropriate measureand it is equal to 54. I used the IQR because the graph isskewed.
D) The standard deviation is the most appropriate measure and itis equal to 15.52. I used the standard deviation because the graphis approximately bell-shaped and symmetric.
E) The interquartile range (IQR) is the most appropriate measureand it is equal to 23. I used the IQR because the graph isapproximately bell-shaped and symmetric.
