Why Graphs Can Make or Break Your Math IA
Graphs are more than visuals — they’re the language of mathematical communication.
A clear, well-designed graph can make your reasoning obvious; a messy one can cost you marks even if your math is correct.
The IB expects you to use graphs not just to decorate your IA, but to analyze, justify, and interpret your findings.
That’s where RevisionDojo’s IA/EE Guide, Graphing Tools, and Exemplars come in — helping you create visuals that strengthen your arguments and meet IB formatting standards.
Quick-Start Checklist
Before you start adding graphs:
- Identify what each graph will show (pattern, relationship, or comparison).
- Use RevisionDojo’s Graphing Tools to format axes and labels clearly.
- Keep scales consistent across related graphs.
- Include short, precise captions explaining meaning.
- Avoid clutter — every visual should serve a purpose.
Step 1: Use Graphs to Communicate, Not Decorate
Many students include too many graphs just to “look mathematical.”
Examiners can tell immediately when a graph is filler.
Every graph must communicate an idea.
Ask yourself:
“What question does this graph answer?”
RevisionDojo’s Graphing Guidelines help you decide which visuals actually add value to your argument.
Step 2: Label Everything Clearly
Each graph should stand alone — even if someone only reads the figure, they should understand it.
Include:
- A title describing the relationship (“Height vs. Time for a Projectile”).
- Clearly labeled axes with units.
- Consistent scales.
- A legend (if applicable).
RevisionDojo’s IA Graph Templates automatically generate graphs in IB-approved styles — no formatting guesswork needed.
Step 3: Choose the Right Graph Type for Your Data
The wrong graph can distort meaning. Use the type that matches your mathematical goal:
- Scatterplots: Show relationships and correlations.
- Line graphs: Display continuous change or trends.
- Histograms: Represent data distributions.
- Boxplots: Summarize spread and outliers.
RevisionDojo’s Graph Type Selector can recommend the best format based on your dataset and analysis type.
Step 4: Use Graphs to Support Modeling
When you’re building or testing models, graphs are your best friend.
Overlay your model curve on top of your data to show fit visually.
Example:
“The exponential model aligns closely with the data points, suggesting rapid growth that slows over time.”
RevisionDojo’s Model Overlay Tool helps you display data and function curves clearly on the same plot — perfect for Criterion C: Mathematical Presentation.
Step 5: Annotate Key Points
Don’t assume examiners will spot your insights — point them out.
Mark features like:
- Intercepts
- Turning points
- Inflection points
- Outliers or anomalies
RevisionDojo’s Annotation Feature lets you highlight these directly on the graph — turning raw visuals into interpreted evidence.
Step 6: Keep Graphs Clean and Minimalist
Visual clutter distracts from clarity. Avoid:
- 3D effects
- Excessive gridlines
- Unnecessary colors
RevisionDojo’s graph generator keeps all visuals clean and IB-compliant. Remember: simplicity is sophistication in mathematical communication.
Step 7: Maintain Consistent Formatting Across Graphs
When multiple graphs are used, consistency matters.
Use the same:
- Font style
- Axis scaling (where possible)
- Color scheme
This creates a cohesive, professional look. RevisionDojo’s Style Sync Tool applies uniform formatting across all your IA visuals automatically.
Step 8: Interpret Every Graph in Words
A graph alone earns no marks — it’s your explanation that earns them.
After each figure, include a 1–2 sentence interpretation:
“This graph shows a near-linear relationship, confirming that the data can be modeled effectively with a linear regression.”
RevisionDojo’s Exemplar IA samples demonstrate concise, examiner-approved phrasing for graph commentary.
Step 9: Compare Models Visually
If you test multiple models, graphs are ideal for comparison.
Plot them together and explain:
- Which fits better?
- Where do they diverge?
- Why might one be more appropriate?
RevisionDojo’s Multi-Model Comparison Tool allows easy overlay and color-coding for multiple function fits — perfect for showing mathematical judgment.
Step 10: Check Graph Quality Before Submission
Before submitting your IA, review your visuals:
- Are all axes labeled?
- Is every graph referenced in the text?
- Does each graph support a point?
RevisionDojo’s Graph Review Checklist ensures every figure meets IB presentation and communication standards.
Frequently Asked Questions
1. Can I use screenshots from my calculator?
Yes, but make sure they’re cropped cleanly and labeled properly. RevisionDojo recommends recreating them in its graphing tool for consistency.
2. How many graphs should my IA include?
Quality over quantity — typically 4–6 meaningful graphs are enough for most explorations.
3. Do captions count toward word count?
No, but explanations in your text do. Keep both concise and relevant.
Final Thoughts
Great graphs don’t just show data — they communicate understanding.
They connect your analysis to your conclusions, showing how math reveals real-world meaning.
With RevisionDojo’s IA/EE Guide, Graphing Tools, and Exemplars, you’ll present visuals that are clean, insightful, and examiner-ready — a key step toward top marks.
