1 N SAMPLING DISTRIBUTION
... has particular importance because it implies that even if data are sampled from a non-normal distribution, the sampling distribution of the mean (or sum) is normal as N becomes large (Hays, 1994). Thus, “normal theory” test statistics regarding means (or sums) can be applied if sample sizes are “suf ...

If the chi square value is > the critical value, then it is seen as a “statistically significant” difference – meaning that the validity of the hypothesis would be under question, suggesting tha ...

... This stat converts the difference in means to a “t stat”, which can be evaluated with a t distribution. Recall that the t distribution is like a standard normal distribution, corrected for small sample sizes. There are different t distributions for different sample sizes (degrees of freedom). The de ...
