Cyclistic Ridership Analysis

Python analysis artifacts, a dimensional BI model, and a financial scenario explorer.

Source figurePython analysis artifact
Python chart of daily bike ride counts, with date on the horizontal axis and ride count on the vertical axis.
Daily ride counts · Python analysis artifact. The chart’s source run is separate from the BI demonstration export.
Question, contribution & scope
The question
How do casual and member usage patterns differ, and how could an analytical model support a membership-conversion decision?
The approach
Separate data preparation, exploratory analysis, dimensional modeling, and scenario assumptions so each can be inspected on its own.

A modular Python pipeline, analysis figures, a one-fact/six-dimension BI structure, DAX definitions, and a browser-based scenario model.

The BI export contains 61,973 demonstration records. The repositories expose the analytical workflow and modeling logic, without establishing realized commercial results.

Scope: Independent work, not a client engagement. Data-generation code is present in the source; historical provenance and the original run behind the Python figures are not independently established. Financial outputs are hypothetical.

Most real systems cross more than one discipline. Bring the constraint and we will map the smallest reliable path through it.
