experiment
An experiment is an investigation looking for a causal
relationship in which an independent variable (IV) is
manipulated and is expected to be responsible for
changes in the dependent variable (DV).
2 types
lab
field
DV dependent variable
what is being measured expected to be due to the change of the IV
IV independent variable
what is under investigation what is being manipulated and controlled
the WHAT
AIM
uncontrolled variable
can be done randomly they will effect the DV so the IV is not the reason for the change ex: outside noise
stuatiunal varabiles
experimental condition
different levels of the IV
control condition
or control experimental condition
does not have a IV its used as a baseline
Laboratory
are conducted in a lab with artificial surroundings not in natural envorment
as high controls
controls
when all variables are kept consent in different levels of the IV
Standardization
when all procedure is kept the same for all participants in each experimental condition
reliability
is the consistency of measures
validity
the extent to the researcher is testing what they are claiming
making sure that the change in the DV is due to the IV
replication
keeping the procedure of study the exact same when attempting to verify results or be able to repeat it
operationalization
making the IV and DV measurable of quantified
