Stand somewhere safe near a road. For 10 minutes, tally cars by colour. You've just done your first survey.
Edit the data — the chart follows
Running the count
- Pick one safe spot and a fixed time window (10 min works well).
- Tally each passing car into its colour with five-bar gates.
- Turn the tallies into a bar chart — the tallest bar is the most common colour.
- Repeat at a different time of day and compare the mixes.
Your turn
Out of 40 cars, 12 were white. What fraction is that — and roughly what percent?
Where you'll meet this
Traffic surveys, footfall counts and audience measurements all start exactly like this: pick a spot, tally categories, plot the result.

What you'll discover
- White, black, silver and grey dominate everywhere
- Bright reds and blues are rarer than you'd expect
- Different times of day give different mixes (commute vs school run)
Plot your tally as a bar chart. Compare with a friend who counted at a different street — same world, different samples.
