Notes for Session 2, Part C

Note 12

Another way to think of an interval is as a boundary; namely, that the measurement is going to fall within a range given by an upper and lower boundary. The range is determined first by the smallest measuring unit on the instruments being used (the precision unit) and then by the maximum possible error for that precision unit. Discuss or reflect on why the maximum possible error cannot be more than half the precision unit.

Note 13

If you are working in a group, be sure to discuss the idea of accuracy. How do maximum possible error and relative error differ? Why do you think relative error is calculated as a ratio? How might we improve our approximations when measuring?
