Designing Questionnaires

Objectives: To understand, interpret and design questionnaires to collect data.

A questionnaire is a set of questions designed to obtain data from a population.

Anyone who answers a questionnaire is called

a respondent.

All questionnaires should:

Be clear and brief as possible.

Use clear and simple language.

Minimise bias

Should not ask leading questions e.g., Why do you think pubs should be open 24 hours day?

Types of Questions:

Open ended question Closed question

Has a fixed set of responses and a scale of

opinions, e.g.

“English football supporters are a bunch

of hooligans”Strongly agree Agree No View Disagree Strongly

disagree

Has no suggested answers and will give people a chance to respond how they want.

What’s wrong with this question?

• What do you think of our much improved brand of Coca Cola?

This question is biased.

It is a leading question

However, to test whether or not a survey will be a success in terms of receiving the required information, often, a pilot survey is carried out, which is a small replica of the experiment that is needed to be carried out.

Design your own Questionnaire

• Andrew wants to find out about what people think about animal testing.

• Design a questionnaire to show how he could collect his results.

Design your own Questionnaire

• Joanna wants to find out about which is the most popular time that people use the Gym in her town

• Design a questionnaire to show how she could collect his results.

Sometimes it’s easier to use 2 way tables to present our data

• Jan wants to investigate the number of hours pupils spend on homework in each year group.
