Today

• finish discussing results from last time

• setup for first group assignment due next Friday

  • assignment objectives and instructions

  • review repository

• workshop ideas and plan tasks in groups

Assignment objective

Your task: prepare and present a descriptive analysis of the survey responses addressing 2-3 questions or goals of your choosing.

• questions or goals should be of moderate complexity; easy to state and understand but should require a little work to answer

  • too simple: what proportion of students have research experience?

  • better: are students with research experience more confident/comfortable with technical skills than students without, considering coursework history?

Outcomes

The learning outcomes for this assignment are less focused on methodology:

• formulate questions and plan a simple analysis

• practice using a GitHub repo in a team project setting

• prepare a report

• learn one or more new-to-you data manipulation techniques

Assignment set-up

1. accept GH classroom assignment here; this will create/add your team repo
2. clone repo to local
3. review repo contents:

   • data with survey responses and metadata

   • scripts with preprocessing and in-class analysis

   • results with report template for preparing write-up

   • README.md with assignment instructions

Deliverable

Your ‘submission’ will be in the form of commits to the group repository, in particular:

• an updated results/report.qmd file containing your write-up source

• a rendered results/report.html file

Please make final commits by Friday, October 14, 11:59pm PST.

Recall there is a 24-hour grace period; any commits submitted after Saturday 11:59pm may not receive review.

Resources

• lab 2 and in-class analysis scripts/week2-surveys.R

• slack and course staff OH

• MDSR ch. 4 on data wrangling

• RStudio cheatsheets and tidyverse documentation, esp. dplyr, tidyr, ggplot2

Workshopping today

Try to accomplish three goals:

1. pool ideas for questions or themes to explore in the data
2. pair up, divide work, and assign tasks
3. agree on a communication plan for finishing work

   • slack groupchat or similar

   • meeting outside of class sometime next week
