Surveys/observations

Ask a useful question, record one response per person, and use observations to collect information.

In this lesson

Before you start
  • Count small collections
  • Sort into groups
01 / LEARN

Understand the idea.

Ask people or watch carefully

Start with what you want to find out. A survey asks people for an answer. To find a fruit choice, ask each child: Which one fruit would you choose: apple, pear or banana?

An observation records what you see happen. To count vehicles passing the gate, watch the gate and record each car, bus or bicycle as it passes. Asking about favourite vehicles would collect different information.

Keep the question fair

Give everyone the same question and choices. Saying that one fruit is the best may push people towards it. Let each child choose for themselves, then record one answer beside their name so nobody is missed or counted twice.

Choose who should answer before you begin. If your question is about the class, give every child in the class a chance to answer. A few friends' choices may be different from the rest of the class.

Six children choose one fruit each.

02 / WORKED EXAMPLES

See the method in action.

EXAMPLE 01

Plan a fruit survey

Which question is fairer: Is apple the best fruit? Or: Which one fruit do you choose: apple, pear or banana?

Worked solution

  1. 1

    Decide what the survey needs to find out.

    We need each child's own fruit choice, so the question should let them choose freely.

  2. 2

    Check the first question.

    Calling apple the best suggests the answer before the child has chosen.

  3. 3

    Choose the second question for everyone.

    It offers apple, pear and banana without praising one choice; every child gets the same choices.

Answer

Ask the second question and give everyone the same choices.

EXAMPLE 02

Choose an observation

We want to know how many bicycles pass the gate in five minutes. Should we ask which bicycles children like, or watch the gate?

Worked solution

  1. 1

    Find what needs counting.

    The question asks about bicycles passing the gate, rather than which bicycles children like.

  2. 2

    Watch the gate for five minutes.

    An observation lets us see the passing bicycles during the time in the question.

  3. 3

    Record each passing bicycle once.

    One record for each bicycle as it passes gives the count we need without adding favourite-bike answers.

Answer

Observe the gate and record the bicycles.

03 / YOUR TURN

Try it yourself.

Check your understanding

To find the number of rainy days this week, would you survey or observe?

Show answer & reasoning

Observe.

Observe the weather each day and mark which days are rainy. Then count the rainy-day records. Asking people what weather they prefer would not tell us how many rainy days occurred.

  1. Choose a method: survey or observe. You want to know each child’s favourite game.

    Ask each child which game they prefer.

    Survey.
  2. Choose a method: survey or observe. You want to count birds landing on a fence.

    Watch the fence and record each bird in the chosen time.

    Observe.
  3. Ari is recorded twice in a six-child fruit survey. Explain the problem.

    Each child should give one choice.

    Check the original records and remove the repeated response.

    One child has two responses, so the choices are not counted fairly.
  4. How many school days were recorded in the weather table?
    Weather observed over five school days.

    There is one row for each day from Monday to Friday.

    5 days.
  5. Which is fairer: Is red the best colour? Or: Which colour do you choose: red, blue or yellow? Explain.

    It gives choices without calling one the best.

    The second question.
  6. Plan a survey about three playground games. Write your question and one rule for recording the answers.

    Use the same question and choices.

    Record each person once.

    For example: Which one game do you choose: tag, skipping or ball games? Record one answer from every child.
