Statistics and Statistical Significance
In many research studies, the primary question of interest concerns differences between groups. Then the question becomes how were the groups formed. In some studies, the researchers actively form the groups themselves. But then we have a similar question—could any differences we observe in the groups be an artifact of that group-formation process? Or maybe the difference we observe in the groups is so large that we can discount a “fluke” in the group formation process as a reasonable explanation for what we find? In other words, are the results statistically significant?
