As I announced in class, we will take our first midterm exam next Wednesday (Oct 2). The exam will cover the material up to and including linear regression. See below for some tips on how to prepare for the exam.
Note that since the college is closed on Mon Sept 30 (& Tues Oct 1), the exam will be during our next class meeting. The exam should take no more than one hour to complete, so we can use the first 30mins of class on Wednesday to discuss any questions that come up as you study for the exam.
To prepare for the exam:
- start by finishing WebWork set “HW4-PairedData” (due Sunday, Sept 29 at 6p)
- review the outlines/notes/spreadsheets for Classes#1-8 (available under Files and the Schedule page)
- review the WebWork exercises and solutions from “HW2-Graphs”, “HW3”, and “HW4-PairedData” (solutions for HW4 will be available Sunday evening immediately after it closes; solutions for the previous two HW sets are available now)
- in particular, review the following WebWork exercises:
- HW2-Graphs: #2, 3, 4, 10, 11, 13, 14
- HW3: #1, 2, 3, 5, 10
- HW4-PairedData: #1, 3, 6, 13, 14, 20, 21, 22
Note: I have updated the post above with this list of specific WebWork exercises to review:
HW2-Graphs: #2, 3, 4, 10, 11, 13, 14
HW3: #1, 2, 3, 5, 10
HW4-PairedData: #1, 3, 6, 13, 14, 20, 21, 22
I have gotten some questions about HW4, specifically #17.
Since I didn’t cover the concepts in that exercise in class (SST – Total Sum of Squares, SSR – Regression Sum of Squares, and SSE – Error Sum of Squares), that question will count as extra credit, and those concepts will not be on the exam tomorrow!
Same for the exercises asking about the coefficient of determination (r^2)–those exercises will be counted as extra credit, and I won’t ask about the coefficient of determination on the exam.
Please focus on understanding the WebWork exercises I listed in the post above.
