- Conduct a chi-squared test for independence (hypotheses, conditions, math, conclusion)
- Conduct a chi-squared test for goodness of fit (hypotheses, conditions, math, conclusion)
- Know how to find expected counts (for both types of test)
- Find degrees of freedom (df) for both kinds of test
- Know about the chi-squared distribution (its characteristics)!
After the quiz tomorrow we will work on a free-response question to practice our t-tests and t-intervals for slope! If you do not finish in class this will be your weekend homework, to be checked on Tuesday! (So if you have Chem/Environmental/Psych on Monday you can focus on studying for those!)
And don't forget -- you can do some homework extra credit AND some extra studying for this quiz! Complete AND SCORE the 2011 free response problem on the back! This must be done by Friday (quiz day)!
- This time we are given our observed counts, expected counts, chi-squared value, and p-value--so we won't need our graphing calculators!
Finally, if you want extra credit test points you must come to complete the 2016 practice test (and turn it in) by next Thursday after school!
- (I won't be here after school next Friday, I unfortunately have to leave early again for another appointment).
- Come after school, during G (Tues/Thurs/Fri), or H period to work individually or with some classmates on the practice test
- Or come after school on Monday, Weds, or Thursday!
- When you finish, complete an answer sheet (you must get this from me when you're here) and turn it in (stapled to the front of your test)
- I will then grade this to determine your extra credit points
- Then you'll get your tests back on Monday 5/8
