The pre-lab for part 2 of the Analysis of Colas lab (1/16) asks you to create a detailed scheme for creating a very precise calibration curve. In order to create the best calibration curve you can, please:

1. Graph your calibration curve from week 1, do a linear fit and get an R squared value. Remember that a perfect line has R squared = 1. If your value is below 0.9 (or even if it’s above), consider how to improve it…
2. Talk to people from at least two other groups about how they created their calibration curves and what their R squared value was. Think about whether incorporating some of their methods might improve the precision of your own.
