Chapter 10 Flashcards
(23 cards)
variables in experiment
independent variable
dependent variable
control variable
independent variable
being manipulated
almost all manipulations are CATEGORICAL
dependent variable
in experiment they will be CONTINUOUS
control variable
something controlled for everyone
design
independent groups (between-subjects) within-groups (within - subjects)
order effects - only with within group
problem with confounds - order within you present the manipulations (level of manipulation)
practice
carryover
pratice effects -
when you practice before the actual study you get practice on it
ex- always practicing the balance with the power balance bracelet before actually getting tested
carryover
when the participants remember what they did before & do the same thing again
how to get rid of oder effects?
counterbalancing - balancing the order
practice effects - have them go in different orders, have them use the balance bracelet first & then without

carryover effects -
which groups uses order effects?
within group designs only
independent groups
participants only participate in one level of the manipulation
within groups
all participants participate in more than 1 level of the manipulation
confounds
variable that could be the explanation for your outcome, that was unintended
- systematic
- unsystematic
systematic variables
something that is in the research
ex- in the power balance study having practice is a systematic variable
unsystematic variables
things that change the outcome that the research does effect - if you use random assignment than this doesn’t matter
ex- the strength of each individual in the power balance test
selection effect
characteristics of the participants are what is really describing the outcome - use random assignment
independent group design
only one form of manipulation per participants
posttest
pretest/postest
postest
post manipulation - manipulation, test, manipulation, test
pretest/postest
after manipulation - test, manipulation, test
within groups
all participants experience more than 1 level
concurrent measures
repeated measures
concurrent measures
trying to figure out the preference of the participants (not very common)
repeated measures
experience 1 level then measures, then experience another level & measured
