Research methods Year 1 Flashcards
What is a laboratory experiment?
An experiment conducted in a controlled environment where the IV is manipulated.
What is a field experiment?
An experiment conducted in a natural setting where the IV is still manipulated.
What is a natural experiment?
An experiment where the IV is naturally occurring and not manipulated by the researcher.
What is a quasi experiment?
An experiment where the IV is based on existing differences, such as gender or age.
What is an independent variable (IV)?
The variable that the researcher manipulates.
What is a dependent variable (DV)?
The variable that is measured.
What is an extraneous variable?
A variable that could influence the DV but is not the IV.
What is a confounding variable?
An extraneous variable that has influenced the DV.
What is operationalisation?
Making variables measurable and specific.
What is an independent groups design?
Different participants are used in each condition of the experiment.
What is a repeated measures design?
The same participants take part in all conditions of the experiment.
What is a matched pairs design?
Participants are matched on relevant variables and placed in different conditions.
What is random sampling?
Each member of the population has an equal chance of being selected.
What is opportunity sampling?
Participants are selected based on who is available at the time.
What is volunteer sampling?
Participants self-select to take part.
What is systematic sampling?

What is stratified sampling?
Participants are selected in proportion to their occurrence in the population.
Name three ethical issues in psychology research.

What is qualitative data?

What is primary data?
Data collected first-hand by the researcher.
What is secondary data?
Data previously collected by someone else.
What are the three measures of central tendency?
