Since, walking slow could be a sign of dementia, I better start walking faster to avoid it.

AP Exam day! Good luck to all the students who have been working so hard to prepare. Know that we are rooting for you! #apstats #MTBoS #statschat #gameday

AP Exam Tip: Know your inference. One sample or two samples? Means or proportions? Interval or test? #apstats #MTBoS #statschat https://t.co/GucPlEVdi5

[Math Medic (artist formerly known as Stats Medic) @TheStatsMedic]

AP Exam Tip: Do not leave anything blank. You are not marked down for guessing. #apstats #MTBoS #statschat

[Math Medic (artist formerly known as Stats Medic) @TheStatsMedic]

AP Exam Tip: Clearly communicate your understanding. Correct answers are usually not enough for full credit. #apstats #MTBoS #statschat

[Math Medic (artist formerly known as Stats Medic) @TheStatsMedic]

AP Exam Tip: Always include context in your answers. Just do it. #apstats #MTBoS #statschat

@MiddletownSS Seems like the "Stay in your lane" guy got way out of his lane.

A BBQ sauce guy should only give takes on BBQ sauce. 🤡

AP Exam Tip: When using your calculator to perform a two-sample significance test for a difference of means, don’t POOL. #apstats #MTBoS #statschat

[Matthew Cohen @CohenAPStats]

Sometimes called p-pooled (especially when using Calculators).

[Math Medic (artist formerly known as Stats Medic) @TheStatsMedic]

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 formula. #apstats #MTBoS #statschat

AP Exam Tip: When asked to describe a distribution, be sure to address shape, center, and variability in the context of the problem. #apstats #MTBoS #statschat #SOCV

[Math Medic (artist formerly known as Stats Medic) @TheStatsMedic]

AP Exam Tip: When asked to compare two distributions, be sure to compare shape, center, and variability in the context of problem. Don’t simply list. Use words like “greater than, less than, similar to”. #apstats #MTBoS #statschat #SOCV

[Math Medic (artist formerly known as Stats Medic) @TheStatsMedic]

AP Exam Tip: If you are using a calculator command to answer a free response question, be sure to label each input. Example: binomialpdf(n=20, p=0.80, X=14) #apstats #MTBoS #statschat

[Math Medic (artist formerly known as Stats Medic) @TheStatsMedic]

AP Exam Tip: Use -ly words to avoid making too bold of a statement. “The data are approximate-ly normal. The scatterplot is fair-ly linear. The residual plot shows a slight-ly curved pattern. #apstats #MTBoS #statschat

[Math Medic (artist formerly known as Stats Medic) @TheStatsMedic]

AP Exam Tip: When asked to describe the relationship between two quantitative variables, be sure to address the direction, form, strength, and any unusual features in the context of the problem. #apstats #MTBoS #statschat #DUFS

[Math Medic (artist formerly known as Stats Medic) @TheStatsMedic]

AP Exam Tip: When interpreting slope and y-intercept for a regression equation, be sure to use the word “predicted” or “estimated” in front of the y-variable. Also include a direction by using "increases" or "decreases" #apstats #MTBoS #statschat #yhat
