Research Methods 5 Flashcards
What ‘s quantative data
- Concerned with the quantity, represented in numerical form
- quantative data collection techniques involve experiments, observations using behavioural categories and correlation
What is the experimental method?
The experimental method aims to determine cause and effect through the manipulation of variables.
What is a laboratory experiment?
A laboratory experiment takes place in a carefully controlled environment. The IV is manipulated by the experimenter.
Example: Milgram’s research into obedience.
Advantage of a laboratory experiment?
Easier to control all variables, allowing determination of whether the IV affects the DV.
Disadvantage of a laboratory experiment?
Lacks ecological validity, meaning findings cannot be generalized to the real world.
What is a field experiment?
A field experiment takes place in the real world, with the IV manipulated by the experimenter.
Example: Bickman’s research.
Advantage of a field experiment?
Has ecological validity, allowing findings to be generalized to the real world.
Disadvantage of a field experiment?
Lack of control of variables, which may affect the dependent variable.
What is a natural experiment?
In a natural experiment, the IV is naturally occurring and not manipulated by the researcher.
Advantage of a natural experiment?
Allows study of areas where IV manipulation is not possible for practical or ethical reasons.
Example: Institutionalized Romanian orphans.
Disadvantage of a natural experiment?
Lack of control of variables, increasing the likelihood of confounding variables affecting results.
What is a quasiexperiment?
A quasiexperiment involves an IV that already exists, such as age or gender, and is not manipulated.
Advantage of a quasiexperiment?
Allows study of areas where IV manipulation is not possible for practical or ethical reasons.
Disadvantage of a quasiexperiment?
Researcher cannot randomly allocate participants, leading to potential confounding variables.
What is a self-report technique?
A self-report technique involves participants explaining their own beliefs, opinions, or attitudes.
What is a questionnaire?
A questionnaire is a set of written questions to which participants record their own answers.
Advantage of a questionnaire?
Participants can answer without the researcher present, reducing experimenter bias.
Disadvantage of a questionnaire?
If wording is unclear, participants may misunderstand questions, leading to inaccurate answers.
What is an interview?
An interview is conducted face to face, with participants answering questions verbally.
Advantage of an interview?
Allows clarification of questions, ensuring participants understand what is being asked.
Disadvantage of an interview?
Participants may present themselves favorably due to social desirability, leading to untruthful responses.
What is a structured interview?
Structured interviews involve predetermined questions asked in a fixed order.
Advantage of a structured interview?
Easy to replicate as each participant receives the same questions, enhancing reliability.
Disadvantage of a structured interview?
May lack validity as the researcher cannot vary questions for more information.
