Science Inquiry Skills Flashcards
What is the negative participant role?
where the participant attemptts to discern the experiments hypothesis, but only to destroy the credibility of the study
What is the good participant role?
occasionally participants behave in socially desirable ways in attempt to live up to the experiments expectations & support the hypothesis
what are experimenter effects?
personal characteristics of the experimenter and their behaviour during the experiment, that may affect the research
What is the placebo effect?
The placebo effect is a participant variable that refers to an improvement in health or wellbeing, due to the participants belief that the treatment wil be effective
What are participant variables?
variables that affect the way the participants respond in an experiment
What is a constant?
A value that remains the same
What is a research question used for?
Qualitative research
What is a hypothesis?
A statement or testable prediciton about the likley results of the research
What must a hypothesis include?
- Testable prediction
- Independent variable
- Dependent variable
- Sample Population
What is operationalising variables?
This is used to ensure that the researcher is specific about what the IV is and how the DV will be measured
What is the dependant variable?
is what is measured in the research
What is the independent variable?
is deliberately changed by the researcher to determine its effect on another variable
when may observational design be used?
in research topics where it is unethical to deliberately expose a group to an independent variable
What are the benefits of independent groups design?
controlled groups creates a baseline of the data to compare the impact of the independent variable on the dependent variable
How might a longitudinal study impact the results?
repeating similar tests over a period of time may affect the results of the test as the participants “learn” it and get used to being testes
What is an example of a repeated measure design?
A longditudinal study
Why is the repeated measures design effective?
has the advantage of participants being identical in characterisitics and abilities between experimental condtitions, eliminating participant variables as an extraneous variable (EV)
What is a repeated measure design?
uses only one group of participants who are exposed to different experimental conditions
What does every research design include?
at least one independent and one dependent variable
