There is no exercise this week. Focus on part 2 of the project.

Project

Finish (and make sure to push) part 2 of the project. There is no need to submit a link. Unless you renamed your repository, I know where to find it based on your part 1 submission.

Discussion

Find a scientific paper of your choice online that does a data analysis. Explain what types of analyses the authors did (based on the categories described in this module). Also discuss what the (stated or not stated) objective of the paper/study was. Comment on if you think the authors performed the right analysis given their goals, and state your opinion if they interpreted/presented their results properly. If you think they didn’t do their analysis right or didn’t present/interpret their results correctly, make suggestions for what they should have done.

You don’t need to go into modeling details, a big picture description is enough. For instance if the authors clearly did a secondary analysis collected for a different purpose, but present their findings as if they showed causal relations, point out this mis-representation (there’s no shortage of studies like that).

Post your findings and commentary by Wednesday. Then read through and comment on some of the studies your classmates posted.
