WebFormulas and Tables for AP Statistics I. Descriptive Statistics 1 i i x xx nn WebT statistic = (Sample mean – hypothesised mean)/sample standard error Hence we can see that how large or how small the T statistic is depends on how close or far away the sample mean is from the hypothesised mean. If the sample mean is close to hypothesised mean, we will get a T statistic close to zero.
