These are the instructions for the first of two projects that were intended to practice the work done by students during the course of the semester. The list of labs is here.
This website contains R lab code for labs in Bard College’s Fall 2020 for Statistics for Psychology, taught by Prof. Justin Dainer-Best.
This project asks you to practice the skills you have learned about running t-tests and visualizing the results, as well as reporting them. It also expects you to practice using filter() and otherwise subsetting data. This project helps you practice adapting code from previous work to a new question.
Set your working directory if necessary. Check that you’re in the directory you expect by running getwd() in the Console. If you need more help, look at the wiki page on setting a working directory.
You should have downloaded the exercise and data already; today’s file is called “12-test-yourself-I.Rmd”. Either open the file (in R through the Files pane, or by double-clicking on the file in your file browser), or you may be able to open the file from the correct working directory by running the following code:
library(psychRstats)
run_exercise("12-test-yourself-I")
Note that there are no “solutions” for this document.
