Common Mistakes to Avoid
Bar Charts:
- ❌ Unequal bar widths: Makes comparison difficult
- ❌ Not starting at zero: Can make differences look bigger than they are
- ❌ Missing labels: Chart becomes unclear without proper labels
- ❌ Inappropriate scale: Too large or too small for the data
Pictograms:
- ❌ No key: Essential for understanding the data
- ❌ Inconsistent symbol size: Larger symbols suggest larger values incorrectly
- ❌ Poor symbol choice: Unrelated or unclear symbols
- ❌ Inaccurate partial symbols: Estimating fractions instead of calculating precisely
