Topic | Good/Bad | Notes and tips for next year | Comments from Students |
---|---|---|---|
Notes about labs | OK | Give more of a spiel about personal safety. Then give advice about being very careful with instruments. | |
terminology: accuracy, precision, errors | OK | ||
terminology: deviation | bad | don't try to explain standard deviation off the cuff and only partially. Save it for a real thorough discussion | |
terminology: mean, media, mode | OK | use official definitions, be concise | |
mean +/- error | Good | we used the actual oscilloscope lab data and I think had a very enlightening discussion about how to assess the quality of data and whether it is OK to throw data out. How to be objective. I think this was a good lesson. We also by hand constructed a histogram, which maybe was useful, maybe not. | |
Here is the oscilloscope lab data (couldn't figure out how to paste in a table):
