Here are some tips/hints to help you out with your homework:
For the 2016 AP Free Response:
- For part a, describe the distribution! You know this! Use your homework/answer key about Wayne Gretzky and EHHS basketball as a reference! Also use your notes and think about what we discussed today in class!
- Part b asks you to comment on how changing the 8 to 18 will affect the mean and median (median is left off, add this for a little homework extra credit)!
- Think: if I change the largest value from 8 to 18, how will the mean change? Will it increase, decrease, or stay the same? Then, justify your answer--explain why you think this.
- Now, consider the median; if I change the maximum from 8 to 18, will the median increase, decrease, or stay the same? Explain why!
For the 2007 AP Free Response:
- Part a: create a stemplot! You got this! Remember your labels/title and a key!
- Part b: more SOCS! Describe the distribution!
- However, this time you have the entire data set--so we don't need to estimate the mean or median or range or IQR, we can use the 1 Var Stats (or our stemplot) to calculate these!
- Part c asks why it would be misleading to report a measure of center...
- First, actually calculate the measures of center, mean and median (you probably did in b)...
- Consider the values of the mean and median--now, look at your stemplot...why is it misleading to report these values? Write a couple sentences, in context, with your thoughts!
- On Monday part of your homework will be to SCORE your AP free response questions using the online rubrics linked below.
- By scoring our problems and using the rubrics we can get an idea of what the AP scorers will be looking for in our responses!
- Monday's homework:
- Score each part of the question as E (essentially correct), P (partially correct), or I (incorrect)
- Write at least one sentence explaining why you got that score (E,P,I)
- If you got a P or an I, write a sentence or two explaining what you were missing or what you would need to get an E!
- If you scored an E, try to use the answer/rubric to write a sentence describing something you still could have done to improve your answer!
- Do this for each part of the question, then use the scoring rubric to give yourself an overall score of 0 to 4.
- Repeat this process for each questoin! (2016 and 2007).
- If you do this this weekend, you won't have any homework Monday night!
- Here are the links to the scoring rubrics:
And finally, here are the two AP problems in case you lost yours or were absent--you can print them or do them on separate paper:
Oh, and one more thing--I took the paper from you with today's in class example (notes), so here's a screenshot so you can use it to study! (If you were out, record this histogram and answer in your notes as a reference!)
