Your Turn

You’ll be working with the college dataset to run all your analyses.

Create a new project. Make sure you put it somewhere you’ll be able to find it again later!
Download the dataset “college.csv” here.
Create a new R script file or RMarkdown document where you’ll do all of your inferential statistics. Alternatively, download the blank exercises document.
Import the spreadsheet into a dataframe college using readr::read_csv()

Thanks David- this package (summarytools) has turned out to be one of the most powerful tools I have ever used in R. I have been struggling with using 'weights' for analysing survey data in R and recently came across the 'pollster' package. summarytools can do far more than pollster can and brings R almost at par with what STATA in terms of comprehensive summary stats by with or without incorporating weights.
