Week 10

More stats and purrr

Announcements

• Please fill out the course evaluations for the class.
  • Course evaluations are very helpful for making improvements to our classes.
  • If too few students fill out the evaluations, they are not released to us.
  • You might have two evaluations since there are two instructors.

Reminder to fill out post-class surveys

• This is a reminder that 5% of your grade is based on filling out post-class surveys as a way of telling us that you came to class and engaged with the material for that week.
• You only need to fill out 5 surveys (of the 10 class sessions) for the full 5%. We encourage you to fill out as many surveys as possible to provide feedback on the class though.
• Please fill out surveys by 8 pm on Sunday evenings to guarantee that they will be counted. We usually download them some time on Sunday evening or Monday. If you turn it in before we download the responses, it will get counted.

See syllabus section on Post-class surveys
