The Attempt at a Solution
I'm never too sure what kind of thing I'd be expected to do for something like
this.
Here's how I would go about it, but would appreciate any pointers / things to
consider:Representing mock with A, real with B
Mean : A < B implies that the average mark was higher on B
St. Dev : A > B implies that there was a greater spread of marks in A than B
Min, Max : the Min(A) < Min(B) and Max(A) < Max(B), also [Max(A) - Min(A) ]<
[Max(B) - Min(B)] , which implies that the marks were spread out more in A than
B, and supports what was considered from the standard deviation.
IQR: We can find the IQR from the difference between the provided quartiles, so
for A we have ~12 and for B we have ~5.
I'm not too sure what else I would really say about this though?
Thanks
