Does paper type have an effect on mean distance? Averages of the samples vary, but maybe only because of the unmeasured factors. If this is true (and paper type does not affect mean distance), then Var( ¯X i ) = σ2 n where ¯X i is the average distance in the ith sample, n is the sample size and σ 2 is the variance of the error. 21
