B. variance (1 point) 1135029.4 1178981.7
C. standard deviation (1 point) 1065.3776 1085.8092

B. median (1 point) 289.5 253.5
C. mode (1 point)
D. midrange (1 point) 3823 4040
Explanation / Answer
All interpretation of the data points are the following:
Mean, median and model are basically the measures of tendancy.
The mean is at 664 and the median at 289.5 signifying the right skew in the distribution.
The midrange is basically the mid value of the max and min values in the group. For example in 2016 and 2017 we have 3823 and 4040 as midrange. Basically, this is also the measure of maximum spread of the data points in the group
The points B, and C are the meausres of spread. Standard deviation and variance of Group 2016 are lesser than that of 2018.
A. Interquartile range of 2017 is slightly less than of Group 2017 indicating less spread of data points
