Question

Quizplus · Accepted Answer

The size of the difference between groups and the number of cases on which it is based are two key factors that determine if a result is statistically significant. The larger the difference between groups and the larger the sample size, the more likely it is that the result is not due to chance. The validity of the experiment is also important, but without a significant difference and large enough sample size, the result will not be statistically significant. The number of dependent variables used is not as relevant to determining statistical significance.
