1.Add the visitor counts for all five animals. How many people answered the survey?
2.Which animal was chosen most often, and how many visitors chose it?
3.How many more visitors chose meerkat than tiger? Write a number sentence.
4.Draw a bar graph of the visitor survey results. Give it a title, label each animal and use a scale that includes all the counts.
Use this space for your graph.

Part B: Keeper records

Harrison recorded how many pages he read in his animal-care guide over seven days: 4, 7, 5, 7, 3, 6, 7.

5.Write Harrison’s page counts from least to greatest.
6.What is the median number of pages read? Explain how you found it.
7.Find the range of the page counts. What does the range tell you?

Part C: Plan a fair investigation

The zoo wants to know how visitors travel to the zoo. A good investigation uses a clear question, fair data collection and a display suited to the answers.

8.Which question is less leading and easier to answer fairly? A: “You came by bus because it is best, didn’t you?” B: “How did you travel to the zoo today?”
  • Question A
  • Question B
9.Visitors may answer walk, car, bus, train or bicycle. Which display would make it easiest to compare how many chose each travel method?
  • A bar graph
  • A line graph showing changes over time
  • A map of the zoo
10.Write one practical step the zoo team could take to collect this travel data respectfully and fairly.
