This website contains two approaches to the data analysis case study
project from start to end:
Project in SQL and Tableau:
– This was my first approach within the course. Its
focus was on big data wrangling and quick visualization in Tableau
– The used dataset and cleaning process was later updated to be
comparable with the project in R
– The project is embedded in a R Markdown document
Project in R:
– This was my second approach using R. This project is
digging a little bit deeper utilizing some of R’s capabilities
– Some statistics and advanced visualizations have been applied to find
deeper insights
All steps are documented in R Markdown with the relevant SQL and R
codes. All codes are executable from the R Markdown documents available
on GitHub Link.
The analysis in Tableau with dashboards and story point is available
in Tableau
Public.
