🚀 Push it
- 🟢Draw a histogram of a column of your own readings.
- 🟡Put a trend line on a line chart and say what the line hides.
- 🔴Explain why one bar per student cannot show where the scores pile up.
🌐 Make it for real
Open a blank spreadsheet in Google Sheets and build the sample scatter, trend line and histogram.
Twist: change the bucket size until the scores neither flatten into two bars nor split one per student.

✅ Watch for
- A line chart used where dots and a trend line belong
- A bar per student taken for the spread of the class
