What Makes a Good

Questionnaire?

(2)

Learning objectives

Identify the different types of question that can be used.

Learn how these questions can be

used to help us test a hypothesis, or theory. Understand how questionnaires and tallies

(3)

I wonder what

type of

questions

these are?

(4)

Hi. Do you usually

hang out here?

Yes.

Have you seen any

No.

Will you be staying

long?

No.

Are you going off now?

Yes.

Our questioner meets the closed question…..

(5)

Our questioner meets the closed question…..

So typical! A

closed question

always asks

things that require

an either/or

answer, like ‘yes’

or ‘no’.

(6)

Our questioner meets the open question…..

Great. Have just

been speaking to

a closed

question – very

short and sweet.

Hi, how’s it going?

What are your

plans, are you

hanging about?

It depends on

whether I meet

anyone I fancy.

Catch you later.

(7)

Our questioner meets the open question…..

Wow! Now there’s a

question I can enjoy

speaking to! Open

questions allow me

to say exactly what

I want.

(8)

Our questioner meets the order of priority question…..

Tell me, in what

order do you prefer

the following – work,

rest and play?

Well, play would

be first, rest would

be second and

work would be

third.

And if you could

change your colour,

what three colours

would you choose,

in priority order?

Hmm, black would

be my first choice,

followed by pink,

and my third

choice is white.

(9)

Our questioner meets the order of priority question…..

Now, there’s a

question that has

everything in

priority order.

Well, I guess

that’s one way of

finding things out.

(10)

Our questioner meets the multiple-choice question…..

I am conducting a

survey to find the

preferred dessert.

Ice-cream,

chocolate, or fruit

pie?

Chocolate, any day.

And how many

times do you eat

chocolate a week?

1–2 times, 3–4

times or more?

1–2 times would be

my choice.

(11)

Our questioner meets the multiple-choice question…..

Those questions

were easy to

answer!

(12)

(13)

Before you ask a question:

Question the question!

think about the answer you want to get before deciding on the type of question to ask

think about how much detail you need in the answer think how quickly you can then collate all the answers together

think how many different answers you want.

(14)

A

hypothesis

can be called: a belief

a theory

an assumption

You start off with a theory

which you then try to

prove or disprove.

In science, for instance, you may have carried out an

experiment to test a hypothesis.

Hypothesis

I think I should leave…

(15)

To test the hypothesis: a survey is conducted the results are analysed

a conclusion is drawn – was the hypothesis proved or disproved?

Here’s example of a hypothesis: “Teenage girls spend more money on their mobile phones than boys.”

Questioning the question

(16)

Teenage girls spend more money

on their mobile phones than boys.

Now there’s a

job for a few

questions!

If some different questions got

together to produce a

survey/questionnaire, then the

hypothesis can be tested.

(17)

A survey can be conducted using a questionnaire or a tally.

Questionnaire

a set of questions with possible answers on one document the questionnaire is copied and handed out for each

individual to complete by ticking boxes

questionnaires are then collected and analysed.

Tally

a set of questions with possible answers on one document the tally is all done on one sheet. Individuals are asked the questions and answers are marked on the same document the tally sheet is then counted and analysed.

There are different types of questions. A closed

question has a yes/no or either/or answer. Open

questions have answers of any length. Order of

priority questions have more than one answer in order

of preference. Multiple choice questions allow a choice

of one from a selection.

Think about the answer before deciding on the

question.

(23)

A hypothesis is a theory which has to be proved or

disproved.

A survey can be carried out using a tally or a

questionnaire.

A questionnaire is useful to analyse individual

answers.

A tally is quicker to complete but gives less

information.

Results can be analysed to draw a conclusion - was the hypothesis proved or not?
