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” from https://bit.ly/collegedataset
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

Learn More
To learn more about the summarytools
package, check out its vignette.
The grade_class
variable in the dataset is not a factor, but could become one. To learn about factors, check out Chapter 15 of R for Data Science.

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.
