From PBS 39 Education. What is data driven decsion making and why is it needed? Using data is critical in strategies for student achievement.

It's not as easy as it looks to determine which schools are doing better than others. Two different criteria are relevant: is the difference in performance between two schools large enough to matter, which is sometimes termed educational significance or practical significance; and is the difference in performance between two schools real, or could it just be due to chance, which is typically described as statistical significance. Ideally, we are interested in differences that are both practically and statistically significant. But a difference could be large, but not statistically significant (which is often the case when we have a small sample of information about performance), or statistically significant, but very small (in which we are pretty sure that the difference is real, but it's just not very important). (Yes, statistical significance does matter!)
