Data Collection Essentials

A group is planning activities for a future marae visit. Help them collect useful, fair and accurate data. Read each question carefully and show your thinking where asked.

Plan a fair collection

Ana, Keira and Nikau want to find out which learning activity students would most like during the visit. They ask 12 students from different groups. Each student chooses one activity.

Questions 1–4

Use the planning situation and frequency table to answer these questions.

1.The group wants to record the activity each student chooses. Which method best matches this task?
  • Observe students arriving at the marae
  • Ask each student the same clear question and record one response
  • Guess which activity students will prefer
  • Use a list of activities from a different visit
2.Which learning activity received the most choices, and how many students chose it?
3.Do the three counts account for all 12 students? Show how you checked.
4.A student suggests asking, “Wouldn’t you rather learn about food traditions than do weaving?” Explain one problem with this question.

Questions 5–9

Think about how to make data collection clear, fair and useful.

5.Rewrite this question so it is neutral and asks students to choose one option: “Which amazing activity do you want to do?” Options are food traditions, local stories, or weaving.
6.Asking only your closest friends is likely to give a fair picture of what all students prefer. Write true or false and explain briefly.
7.The 12 students who answered are the for this data collection. The activity they chose is the being recorded.
8.Match each data collection method with its example.
  • Survey
  • Observation
  • Existing data
  • Count how many students arrive by bus
  • Check a previous visit's attendance record
  • Ask each student which activity they prefer
