Course 7:
Programming in R
This module covered the basics of using the open-source programming language R for data analysis and visualizations.
We used R studio to manipulate data using the “tinyverse” packages in R. Some of the tools we used were ggplot2, tidyr, tibble, dplyr, and readr.
Using these tools, we then exported results in R Markdown.

Course 8:
Capstone Project
This module discussed the importance of completing case studies for professional development.
During this module, I completed a case study analyzing customer trends for a bicycle-sharing company.
The case study explained the behavioral differences between subscribers and one-time customers to create a marketing campaign. This campaign will then be used to increase the proportion of one-time customers signing up for the company’s membership program.
