Living Bar Charts Worksheet

Arjun, Isla and Evie are planning a community event on a busy city bus route. They survey 24 passengers about which event activity they would choose. Use the results below to build and interpret a living bar chart. In a living bar chart, each person stands in the category they chose; a written bar chart represents the same counts with bars.

Live music — 8 passengers

Food stalls — 6 passengers

Street games — 5 passengers

Art workshop — 3 passengers

Quiet seating — 2 passengers

Read the data

Use the survey results. Show calculations where useful.

1.Which event activity received the most votes, and how many passengers chose it?

2.Which activity received the fewest votes?

3.How many more passengers chose live music than art workshop?

4.Check the total: how many passengers were surveyed altogether?

Make it a living bar chart

Imagine the 24 passengers standing in five groups, one group for each activity. Every person counts as one unit. Then translate the groups into a conventional bar chart.

5.If each person in the living chart holds one sign, how many signs are needed for the food-stalls group?

6.Draw a bar chart of the five activities. Label the axes, add a title, use equal-width bars with gaps, and choose a sensible vertical scale.

7.Isla says the bars should touch because passengers stood next to one another in the living chart. Is she right for a conventional bar chart? Explain.

8.Arjun suggests changing the vertical scale from 0–8 to 4–8 to make the differences look larger. What could be misleading about this?

9.What fraction of the passengers chose either live music or food stalls? Give your answer in its simplest form.

10.A second group of 12 passengers is surveyed. The same proportions choose each activity. How many would choose street games?

11.Evie surveys only passengers waiting at the final stop, rather than passengers from different stops along the route. Give one reason her results might not represent all bus-route passengers.
