Flashcards in Research Methods:variables Deck (10):
What is an extraneous variable?
Anything else affecting the DV other than the IV
What is a participant (subject) variable?
any differences between participants such as age and IQ
What are situational variables?
external/environmental factors that could influence the results such as noise, temperature or other distractions
What are investigator effects?
This is when researchers become too involved with the experiment by giving unconscious cues and hence favoring results. This also refers to the way instructions are given, how materials are presented and how participants are selected.
What are demand characteristics?
This is wjhen participants may look for clues to help them figure out the researchers' intention/aim
DV is then no longer natural and valid
What is a confounding variable?
This is when an extraneous variable is not controlled and confound the results.
What are tghe three ways to control extraneous variables?
What is standardisation?
keeping things the same across all conditions such as age, IQ or environment
What is counterbalancing?
Often used in repeated measure design
It is where participants take part in both conditions where half do condition A then B and the other half to condition B then A.
This rules out things like boredom or practice
