When determining if two groups are statistically significant, the researcher is comparing the parameters of the two populations, which includes mean, variance, and standard deviation. If these parameters are significantly different between the two groups, then the groups are also likely to have different distributions and associations. Z scores and t scores are measures of how far a data point is from the mean and are not as relevant to comparing two separate populations. Summarization values, such as mean or median, may also be different between the two groups but do not necessarily indicate statistical significance.
