Research Methods 1 Variables Flashcards
Reliability
A piece of research is repeated with same method,same results
Valid
Does it measure what it claims to be measuring?
Internail validity
Validity inside study. To what extent is the researcher measuring whats intended or r there extraneous variables effecting
External validity
Extent results can be generalised.either ecological, population or historical.
Population validity
Participants used are typical of which the group in real life are drawn.eg similar group =low pop validity, should reflect general pop
Ecological validity
Behaviour accurately reflects behaviour in normal circumstances. Usually isn’t true to life ,dosnt tell us about real life if done in a lab
Historical validity
Research taken place at diff time accurately reflect behaviour at diff point in time.
I.V
Different conditions in study.
D.V
what u measure .affected by the I.V
Extraneous variables
Factors impacting result other than what you intended
Situational variables
Variables (excuses)from the environment.like in a test if temp is too hot /cold.
Participant variables
Characteristics of individual participants (personal excuses).motivation,if they had coffee that morning for a test harder to control than situational.
Confounding variables
Uncontrolled extraneous variables.may effect D.V therefore reducing internal validity of results.
Confounding variables fail because effect the result…
Cus the researcher failed to identify ,control for an extraneous variable.
Control group
Participants who arnt being tested but the independent variables.they are used for comparison, more scientific.
