About This MicroSim

This three-panel dashboard visualizes how network centrality metrics are distributed across demographic groups. The grouped bar chart (top) compares average centrality across groups. The box plot (bottom-left) shows the full distribution for a selected metric. The equity ratio panel (bottom-right) summarizes the gap between the highest and lowest performing groups using color-coded indicators.

Select different centrality metrics to focus the box plot, and toggle between raw centrality and tenure-controlled values to separate structural effects from seniority effects.

Lesson Plan

Learning Objective

Students will assess centrality distribution across demographic groups, evaluate whether network structure creates equitable access, and propose interventions.

Activities

1. Compare Groups: Examine the bar chart to identify which group has the highest and lowest centrality
2. Examine Distributions: Switch between metrics in the box plot to see if gaps are consistent
3. Evaluate Equity: Read the equity ratios and discuss what "equitable" means in a network context
4. Control for Tenure: Toggle the tenure control and discuss how seniority affects centrality

Assessment

• Interpret the equity ratio and explain what a value of 0.36 means
• Compare raw vs tenure-controlled metrics and explain the difference
• Propose three network interventions to improve centrality equity
