The following is a small data set of 25
observations. I want you to calculate some statistics by
hand to cement the class material. You can use the regular formula
for the variance or the computational formula - I’m just interested
in the correct result. If you use the computational formula, you
will want to calculate a separate row of each value squared in
order to calculate the Sum(x^2). Excel can be used to solve
this problem.
