- Your first exam is graded: here are the results (out of 50), so
that you know how you stand versus the rest of the class:
- Curve: add 2 points (out of 50) to your score. (Note: this hasn't been applied in Canvas). You see how the grades shift when I apply that curve in the distribution above.
- Mean: 76.40%
- Standard deviation: 16.9%
- Usually I make up a key from the work of my students. I haven't done that yet, but I will.
- There was a mistake (on part b. of #5), which resulted in
some correction in scores for the (relatively few) who
tried that one. Apologies for any confusion that may
have caused. Most of you went for the even/odd
problem.
I was trying to say that "exclusive or" implies $(A \leftrightarrow B)'$ -- but I wrote the negation of the exclusive or! Rats...
- Any questions, please visit during office hours, or email me.
- No new material (we're doing 3.2 today). Because the university
was closed on Tuesday, so were we. I hope that you went
sledding, which is what you're supposed to do on snow days.
- I pushed back some deadlines, to reflect that.
- We have a break next week (part of our "spring break"), with
Monday and Tuesday off. So I won't be putting out new material, or
hosting office hours. You can still reach me, however, by email; let me
know if you are struggling with anything.
Enjoy your break!
- Nothing new to report.
