questionnaires Flashcards
what is a questionnaire?
A written self-report technique where participants are given a pre-set number of questions to respond to (thoughts, feelings and experiences).
Can be done in person, by post, online, over the telephone etc
what are strengths of using a questionnaire?
- allows both qualitative and quantitative data about how respondents feel and think to be collected.
- surveys can gather large amounts of data and involve large samples
- not time consuming to administer - can be conducted in person, online, over the phone etc.
- if standardised can be considered reliable (test - re -test).
- validity can be checked - Face, predictive, concurrent.
what are weaknesses of using a questionnaire?
- social desirability bias may lower the validity (accuracy) of the responses.
- can be time consuming to analyse the data, especially qualitative.
- types of data collected has implications (weaknesses of qualitative and quantitative data)
what type of questions can be used in a questionnaire?
- open
- closed - likert scale, rating scales, ranked scales
what are closed questions?
Have preset fixed answers produce quantitative data eg. YES/NO
types of closed questions
- Likert Scale (how strongly the pp. agrees with a statement)
- Rating Scales (how stressed do you feel? 1 = not very, 10 = very)
- Ranked Scales (Ranking choices in preference 1st, 2nd, 3rd).
strengths of using closed questions
- standardised, preset responses mean the questions are reliable as they can be replicated.
- easy to analyse as they usually gather quantitative data, which can be summarised as a graph.
weaknesses of using closed questions
- data lacks detail and depth as it is in the form of numbers, respondents can’t develop answers as they can with qualitative.
- low validity as respondents are restricted to numerical or preset responses which may not accurately represent their thoughts, feelings, experiences etc.
- scales can be subjectively interpreted ie. two pps may feel exactly the same level of stress but will record rating differently on the scale eg. 7 and 9.
what are open questions?
allows pps. to answer freely and in detail, gathers qualitative data.
always use words such as: Explain, Describe
weaknesses of using open questions
- harder and more time consuming to analyse compared to quantitative data because the mean can’t be calculated and it can’t be displayed on a graph, but Thematic Analysis can be used to quantify responses ( aka difficult to convert to statistical data)
- analysing qualitative data may suffer from bias as the interpretation is more subjective (open to interpretation) than compared to the analysis of quantitative data - less valid
strengths of using open questions
- qualitative data is gathered - allows respondents to elaborate on their thoughts, feelings, experiences etc.
- responses are more likely to be valid as responses aren’t restricted and the respondent can elaborate
