Once you complete the installation of R and RStudio, make your own report to repeat the code attached. Make sure to create your own screenshots and report.

Every screenshot in the report should show all 4 Rstudio screens.

ITS 530: Quiz 2 sample report

Visualization with ggplot2 library

See below cheat-sheet on this library for quick reference

https://rstudio.com/wp-content/uploads/2015/05/ggplot2-cheatsheet.pdf

First I am reading my csv dataset

Str(data) showed me general information about my dataset

My dataset has 1803 obs. of 27 variables:

The second picture to show how many null values in my dataset

I have many null variables

Next I will start my ggplot2 visualization

# This quiz we will look at ggplo2 library visualizations

# Our examples are from the link http://r-statistics.co/Top50-Ggplot2-Visualizations-MasterList-R-Code.html

Our first plot is called: Scatterplot. Screens below shows results of my code for two variables from my data. x=R_C_PCT_CLASSES_GT_50, y=IS_RANKED

I basically want to study class size with University rank scale

The chart basically is telling me that Universities with lower rank tend to have less of those large classes

The second chart scatter plot with encoding

Complete the above two charts based on your dataset and any 3 more charts from the http://r-statistics.co/Top50-Ggplot2-Visualizations-MasterList-R-Code.html (Important, the charts and your code should be based on your dataset). Submitting the code and figures from this link as is will not be accepted
