Think of the research question you were assigned to on Monday. You can read on the project page if you'd like.

- What is a potential response variable for a study that answers this question? How could you measure it on a ratio or interval scale?
- What is a potential explanatory variable? What conditions could you create to study this variable?
- What might be the material you assign to these conditions?

- HW 2 grades up on Moodle
- Plus 2 points for everyone, 13a, 16, and 17, were often missed.
- I will be dropping the lowest HW grade at the end.

- HW 3 due Friday by midnight on Moodle! (due to snow day)

- Get into project groups and start discussing
- Informal Analysis and Six Fisher Assumptions
