Questionnaires Flashcards
what are questionnaires
Questionnaires ask people to provide written answers to pre-set written questions.
what type of data does it produce
Quantitative data
what are the types of questionnaires
close ended
open ended
close ended
respondents much choose from a limited range of possible answers that the researcher has decided in advance such as yes, no or don’t know
open ended
Respondents are free to give whatever answer they wish, in their own words and without any pre-selected choices being offered by the researcher
what type of data does it collect
quantitative data
practical advantages of using questionnaires
- They are a quick and cheap way of gathering large amounts of data from large numbers of people, widely spread geographically. For example, Connor and Dewsom posted nearly 4,000 questionnaires to students at 14 high schools in their study of the factors influencing the decisions of WC students to go to uni.
- There is no need to recruit and train interviewers to collect data as respondents complete the questionnaire themselves
- Data is easy to quantify particularly where pre-coded close-ended questions are used
practical limitation
- Data is often limited and superficial. This is because questionnaires need to be fairly brief - most people are unlikely to complete a long, time-consuming questionnaire
- It may be necessary to offer incentives to persuade respondents to complete the questionnaire this adds to cost
- With postal and emailed questionnaires, we cannot be sure that the intended recipient complete the questionnaire and not someone else.
- They are inflexible, once it is finalised, the researcher is stuck with the questions they have decided to ask and cannot explore any new areas that arise during the course of the research - validity
- The questionnaire is drawn up in advance, meaning the researcher must already have some knowledge of the subject and a clear hypothesis to test. This makes it less suitable for investigating unfamiliar topics where the researcher has little idea.
- They are only snapshots - pictures of reality at one moment in time when the respondent answers the questions. They fail to capture people’s attitudes and behaviour change.
who favours questionnaires
positivists
positivism and questionnaires
Questionnaires are representative, they can be generalised to the wider population. They are reliable, objective and a detached method for producing quantitative data, and testing hypothesis.
hypothesis testing
Questionnaires are useful for testing hypotheses about cause and effect between different variables. For instance, using the example of educational achievement, analysis of respondents’ answers could show whether is a correlation between children’s achievement levels and family size. From this, we can make statements about the possible cause of a certain thing based on the correlation made.
reliability
Questionnaires are reliable, that is, if repeated by another researcher, the questionnaire should give us similar results. This is because when the research is repeated, a questionnaire identical to the first original one is used, in the same order. It is a standardised measuring instrument, they also allow us to make comparisons over time and between different places
representativeness
questionnaires collect information from a large number of people, the results stand a better chance of being truly representative of the wider population than with other methods that study only very small numbers of people like experiments or unstructured interviews. The findings can be generalised from the sample studies to a wider population from which the sample is drawn.
reasons why questionnaires are representative
They are large scale - because questionnaires can be distributed quickly and cheaply by post or email over wide geographical areas, they can collect information from a large sample of people.
They use representative samples
how can the representativeness be undermined
The representativeness can be undermined by a low response rate, especially if those who do return their questionnaires are different in some way from those who don’t e.g. educated people. If so this would produce distorted and unrepresentative results, from which no accurate generalisations can be made.
detachment and objectivity
Positivists favour questionnaires because they are a detached and objective (unbiased) method where the sociologist’s personal involvement with their respondents are kept at a minimum. For example, postal questionnaires are completed at a distance and involve little or no personal contact with respondents.
