AP Exam Tip: When defining a parameter, be sure your description is referring to the population and NOT the sample. Avoid past tense whenever possible. #apstats #MTBoS #statschat

AP Exam Tip: When a significance test yields a P-value greater than alpha, we fail to reject the null. Don’t “accept the null”. Just don’t. #apstats #MTBoS #statschat #youfool

AP Exam Tip: Use p-combined only when doing a significance test for the difference in proportions. It is needed to check the Large Counts condition and for the SE. #apstats #MTBoS #statschat

AP Exam Tip: Know how to interpret a P-value. “Assuming the null is true, the P-value is the probability of getting the observed result or more extreme, purely by chance.” #apstats #MTBoS #statschat #holygrail
