Major Tasks
- Business Understanding: Started overall analysis with posed questions in mind.
- Data Understanding: Making sense of data points given by Stackoverflow to use it for analysis. For example: which columns will be helpful to answer a particular question?
- Data Preparation: Performed data wrangling and data transformation. Written a function to draw plotly barchart for repeated code, keeping DRY techniques in mind.
- Data Visualizations: Provided data visualization for a deeper understanding of data like barchart and piechart to convey my findings. Added result statements at the end of every visualization for easy understanding of thought process.
I have followed the CRISP-DM process throughout the project. Completed using Jupyter Notebook.
