If any trend is spotted in the results, it represents a buildup of systematic error which might not be spotted using a random sample. SPC identifi ...

... Does our sample mean of –1.18 provide any evidence that this is not true? Sample mean = -1.181; S.E. of sample mean = 0.459 Statistic: t = -1.181/0.459 = -2.574 Using a computer, or published tables, we obtain p=0.0329 (two-sided) i.e. if the H0 were true there would only be a 3.3 % chance that we w ...
