Common Mistakes to Avoid

❌ Mistake: Not reading the scale carefully

Problem: Assuming each line on the scale represents 1 unit when it might be 2, 5, or 10.

Solution: Always check what interval the scale uses by counting between marked numbers.

❌ Mistake: Ignoring the chart title and labels

Problem: Looking at numbers without understanding what they represent.

Solution: Always read the title, axis labels, and legend before analyzing data.

❌ Mistake: Misreading where bars align with scale

Problem: Reading from the wrong part of the bar or not aligning properly with scale lines.

Solution: Use a ruler or your finger to draw an imaginary line from the bar top to the scale.

💡 Pro Tips for Success:

  • ✓ Cover part of the chart and try to predict what you'll see
  • ✓ Use your finger to trace from data points to scale values
  • ✓ Double-check your reading by estimating first
