Research Methods Flashcards
What is a questionnaire
Respondents record their own anwsers to questions that are structured. Comes in written form and its not face-to-face
What is an advantage of using questionnaires
They can be easily repeated so that data can be colelcted from large numbers of people quickly.
What is a disadvantage of questionnaires
people may not always tell the truth, this might be because it’ll make them look unlikeable, so they lie to seem more likeable
Questionnaire: what is a closed question
Has a fixed number of possible anwsers
- provides quantitative data
Questionnaire: what is an advantage of closed questions
Easy to analyse because data is in numbers, can be summarised using avarages or graphs, making it easier to draw a conclusion.
Questionnaire: what is a disadvantage of using closed questions
participants may not be able to express how to truely feel due to low choice of anwsers. Therefore data is low in validity
Questionnaire: what is an open question
allows respondents to provide their own anwsers.
- produces qualitative data
Questionnaire: advantage of open question
Participants are able to express what they actually think rather than being restricted by multiple choice anwsers.
- Increases validity of results.
Questionnaire: disadvantage of closed questions
More dificult to draw conclusions because there are likely to be a wide range of anwsers.
Questionnaire: What are ranked scales
type of closed question where respondents are asked to assess their views based off scales (1-5 or 1-10)
Questionnaire: ranked scales advantage
produces quantitative data which is easier to analyse making it easier to draw conclusions.
Questionnaire: ranked scales disadvantage
Participants may respond in patterns, like only selecting high numbers or only selecting the middle numbers.
What are the 4 different types of sampling
Random
Stratified
Volunteer
Opportunity
What is a random sample
sample of participants produced using a technique where each person has equal chance of being selected
Example of random techniques
giving everyone in a population a number and using a random number generator to selected a sample.
Random sample: Advantage
Gives an unbaised sample as all members of a population have an equal chance of being selected
Random sample: Disadvantage
often not random as some selected participants may not wish to participate, leaving the final sample to be more of a volunteer rather than random
what is stratified sample
participants selected from different subgroups in the target population based of the proportion of the subgroups frequency in that population.
example of stratified sample
If the target population contains 10% 18-20 year olds, then the sample should contain 10% 18-20 year olds.
Stratified sample: advantage
most representative sampling technique as..
- all subgroups are represented in the same proportion as the target population
