Week 3: Exploring Dataframes — grouping and plotting
Learning Objectives
- 03A I can clean and transform text data using string operations in DataFrames.
- 03B I can group data to calculate aggregates such as counts, means, or sums.
- 03C I can produce and interpret histograms, scatter plots, line plots, and bar charts to explore a dataset visually.
Perspectival Reading
Reading: TBD
Reflection Questions
- Aggregation compresses individual experiences into summary statistics. What is lost in that compression?
- Visualizations make certain patterns visible and others invisible. Who designs them, and for whom?
- The choice of grouping variable structures what stories a dataset can tell. What stories go untold?
