Answer:1st Rearrange A and B from lower to higher data points:


A ={ 1 2 3 3 4 5 6 6 6 7}        and                B = { 2 2 2 2 3 4 5 6 7 8}

---------------------------------                             --------------------------------

a) Median = 4.5                                           Median = 3.5

b) Mean = 4.3                                              Mean = 4.1

c) Mode = 3                                                 Mode = 4

d) Range = 6                                                Range = 6


Conclusion:

---------------

A is more performing than B (Median near Mean in A)

Data in A is negatively skewed (Median>Mean) and in B positively Skewed (Median < Mean)
