Creating a Summary Sheet

Problem Explanation
Explain the problem in your own words and main objectives
Model Description
Describe the main idea of your mathematical approach, methods to solve.
Key Results
Highlight your most important conclusions. Graph, Chart, Bar plot visualization
A well summary sheet serves as the first impression of your mathematical modeling work. It should be clear, concise, and readable by anyone unfamiliar with the mathematical details, while accurately conveying the essence of your approach and findings.
Main Sections of Full Report
Full Report: Solution and Analysis

Results Presentation
Share outcomes using tables, charts, and graphics
Validation and Testing
Verify model makes sense in real-world terms
Solution Process
Describe analytical/computational/optimized methods
The solution and analysis sections form the core of your mathematical modeling report. Begin by explaining your solution process, including any analytical/computational tools or algorithms used. Then demonstrate how you validated your model through testing different scenarios. Finally, present your results clearly with appropriate visualizations that highlight key findings in compact form.
Creating Effective Visual Graphics
What makes a good visual for mathematical modeling?
Effective visuals clearly communicate complex mathematical relationships without requiring extensive explanation. They should be self-contained with proper labels, titles, and legends.
What types of visuals work best for different model aspects?
Use line graphs for trends over time, bar charts for comparisons between discrete categories, scatter plots for relationship between variables, and flow charts or diagrams for processes and systems.
How should I format my visuals for maximum clarity?
Use consistent color schemes, ensure text is readable, include clear axis labels with units, and add concise captions explaining the significance of each visual.
Should I create visuals by hand or use software?
Software-generated visuals (using Python, MATLAB, or Excel) are generally preferred for precision, but well-executed hand-drawn visuals can also be effective if they clearly communicate your ideas.
