Last Night’s homework “trees in a forested area” example:

• This is a nice reminder of  how to interpret a p-value  for a significance test for a proportion

---THESE ARE EXPLANATIONS FOR FORMULA SHEET FOR AP STATISTICS, COMMON STUDENT ERRORS---  



FORMULA SHEET FOR AP STATISTICS:

• nice advice to print your formula sheet and start putting notes right on that sheet now since it’s an open book/open notes exam 😊
• I: Descriptive Statistics: Statsà Calc 1:1-Vars Stats or 2: 2-Vars Stats or 8: LinReg(a + bx) instead of some of the “complicated” formula in this section
• II: Probability and Distribution:  You can add (write it in) the formula P(A or B) = P(A) + P(B) – P( A and B) to this section; put any notes, formula, calculator functions in the binomial and geometric distribution section
• III: Sampling Distribution and Inferential Statistics:  put any notes or more specific formula for z-scores, t-scores, confidence intervals, etc. here; delete Chi Square (CB Unit 8 topic) for this year’s 2020 exam; cross out Inference for Regression (CB Unit 9 topic) for this year’s 2020 exam

COMMON STUDENT ERRORS:

• nice run through of the 6 common errors for Exploring Data Analysis (EDA)
• nice run through of the 8 common errors for Experimental Design
• nice run through of the 4 common errors for Probability
• nice run through of the 7 common errors for Statistical Inference

Try the homework MC 2002 #24 if you can for tomorrow’s lesson 😊
