What are the 5 ethical guidelines?
- Debrief
- Informed consent
- Right to withdraw
- Competent researcher
- Deception
What is an alternate hypothesis?
A specific testable prediction containing variables, and will state either a difference or relationship.
Directional hypothesis
States the direction the results will go in (more, less, positive, fewer)
Non-directional hypothesis
Does not state the direction of the results, leaving it open
What is the aim of sampling methods?
To ensure a representative sample of participants is used, so can be successfully generalised.
Opportunity sampling
Sample of those who are available at the time of the study
Random sampling
Every member of the population has an equal chance of being chosen.
Stratified sampling
Involves classifying the population into categories and then choosing a sample which consists of participants from each category in the same proportions as they are in the population.
Volunteer sampling
Volunteering when asked or in a response to an advert.
Advantages of random sampling
- No bias
- Clear how the sample is chosen, process can be explained
Disadvantages of random sampling
- Difficult to ensure everyone is available
- Some people might not want to take part in the study
- There can be bias in that there may be more of one group than the other, such as more male soldiers than female
Advantages of stratified sampling
- Each group is represented, so conclusions can be drawn
- Efficient to ensure representation from each group
Disadvantages of stratified sampling
- Difficult to know how many of each group to choose
- Some groups may not be important fro the study
Advantages of volunteer sampling
- More ethical as they chose to take part
- Volunteers are likely to be interested so less likely to give biased information, less likely to have social desirability or demand characteristic.
Disadvantages of volunteer sampling
- Takes long time to get sufficient numbers
- Participants may be similar, so there may not be representation
Advantages of opportunity sampling
-More ethical because the researcher can judge if the participant is likely to be upset by the study
- Researcher has more control over choosing, more quick and efficient
Disadvantages of opportunity sampling
- More chance of bias - choosing people you know, people of own age, friendly looking people etc.
- Self selected, so would rule out anyone not available or not willing
Types of closed ended questions
- Fixed choice questions, with yes/no response
- Likert scale questions, selecting from a fixed set of choices to rate agreement to statements
- Ranked scale question, ranking choice relative to other options
Strengths of closed ended questions
- Quick and easy to answer
- Researchers can easily analyse data, percentages and averages can be worked out
- Questions are all the same so is more reliable
Weaknesses of closed ended questions
- Limited amount of information
- Answers may not match what the participants would like express
- Choice answers could mean different things to different respondents, such as ‘unsure’ could mean ‘don’t know’, so lacks validity
Strengths of open ended questions
- Respondents can answer freely
- Allows them to elaborate on their answers and justify opinions
-More detailed and valid, true to real life
Weaknesses of open ended questions
- More time and effort for respondents
- Qualitative analysis which can lead to subjective interpretation that is difficult to analyse
- Respondents often fail to complete their answers
Structured interviews
Standardised so all respondents are asked same questions
Strengths of structured interviews
- Easy to administer
- Do not need to establish a rapport between researcher and respondent
