Data: Basic Data Analysis in RStudio
Background: This course is all about data visualization. However, we must first have some understanding about the dataset that we are using to create the visualizations. A resource is provided to you to learn the simple commands in RStudio. You are also expected to locate appropriate available resources to learn the functionalities of RStudio.
Assignment:
Use RStudio to generate a word document with basic data analysis of the following dataset: dataset_price_personal_computers.csv
Use the following video from Dr. Francis to learn the simple commands to conduct basic data analysis with RStudio: Basic Data Analysis in RStudio.mp4
