Data Detective Investigation

Ruben, Wiremu and Isla are helping plan a Matariki celebration. Use the survey data to investigate what people would enjoy. Show your thinking and answer using the evidence.

Plan the investigation

The group asks: “Which activity would you most like at our Matariki celebration?” Each person chooses one activity. The choices are star stories, kite-making, waiata, and night-sky viewing.

1.Why is this a useful investigative question? Choose the best answer.
  • It can be answered by collecting choices from a group.
  • It has exactly one answer for everyone.
  • It asks people to guess the weather next year.
2.One person does not want to share their choice. What should the data detectives do?

Read the survey results

The group asked 24 volunteers. Here are their results:

3.How many people chose star stories or kite-making altogether? Show the addition you used.
4.Which activity received the most votes, and how many more votes did it receive than night-sky viewing?
5.Check the total number of votes. Does it match the 24 volunteers? Write the calculation and explain what you notice.
6.Make a tally chart for the four activities using the results. Group tally marks in fives.
7.The organisers can run two activities. Which two would you recommend based on the survey, and how many votes did they receive altogether?
8.The volunteers were people who chose to take part. Give one reason the results might not represent what everyone at the celebration wants.
9.Suggest one follow-up question the organisers could ask to plan the celebration better.
