Flashcards in Research Deck (37):
varies systematically with the IV
degree to which research can be generalised to other people (population validity) setting (ecological validity) time (historical validity)
don't vary systematically with IV but have an effect on the DV
observed effect due to experimental manipulation
how a study mirrors the real world
observed effect genuine?
technique to overcome order effects with repeated measures design
in repeated measures design
order which conditions are carried out has effect on DV
controlled experiment conducted outside the lab.
ppts usually unaware they're participating.
hard to control extraneous variables - low internal validity.
Greater mundane realism - high external validity
carried out in controlled setting.
high internal validity.
low ecological validity - ppts aware being studied.
unethical to manipulate IV.
Measure effect naturally varying IV has on DV.
No causal relationships made.
IV naturally occurring - not made to very by anyone.
Measure DV - lab?
No causal relationships.
ppt unconsciously aware of aims
anything investigator does that has effect on ppt performance
identify subgroups according to their frequency in the population
ask group similar to ppts is agree to take part.
assume ppts would agree.
used if lack informed consent
behaviour observed under controlled conditions
Observing people without them knowing
observing behaviour in everyday setting which has not been manipulated.
observer separate from participants.
not involved in study.
participants aware being studied
observer taking part in activity being observed
count number of times behaviour occurs.
systems used to organise observations - behavioural categories
record behaviours in a certain time frame
Social desirability bias
answer questions that presents them in a better light
predetermined range of answers.
ppt selects one.
pots provide own answers
two measured variables in correlation analysis
give value in a certain range (scale 1 - 10)
between -1 and +1
how closely co-variables are associated
variable that comes between two other variables and explain the association between them
observational study where behaviour is observed indirectly
Negative skewed distribution
scores bunched towards right.
mean affected by extreme scored to the left.
Positive skewed distribution
scores bunched towards left.
mean affected by extreme scores to right.
One tailed test
