    Mods should move this to Maths, this is statistics stuff that I've learned at A-level. All I remember is those terms referring to "hypothesis tests".

    Mods will do this more efficiently if you can please report the first post as a Thread Move.

    confidence intervals: calculated mean +/- (100 -((100 - % of confidence points)/2))** x standard error of mean

    ** Value found on the percentage points table.

    E.g. mean was found to be 5, construct 98% confidence interval. n = 25, SD = 1.2

    5 +/- (99% points)x(1.2/5)

    Comments should discuss whether the claimed mean is within your confidence interval or not.
