so if we're measuring frequent use of caffeine and its correlation with high anxiety what are the co-variables?
caffeine intake / anxiety level
6 of 33
what woudl a positive correlation be in this sense?
more caffeine higher anxiety
7 of 33
if also had them record how many hours sleep what would we expect to find hypothesesy?
more caffeine less sleep
8 of 33
why would this be a negative correlation?
one variable rises the other falls
9 of 33
and if we also asked them to record number dogs on street what would we expect to find?
no relationship
10 of 33
so what kind of correlation?
zero correlation

what happens in experiment?
researcher manipulates iv to record effect on dv
13 of 33
as result of this deliberate change in one variable its possible to infer?
iv caused observed changes in dv
14 of 33
in correlation no manipulation of one variableand tehrefore not possible to establish?
cause and effect
15 of 33
people can be anxious for all kinds of reasons and therefore what cannot be disregarded?
thier influence on other co-variable
16 of 33
what are these other variables called?
intervening variables

correlation useful what kind of research tool?
preliminary
19 of 33
why?
provide precise and quantifiable measure of how two covariables related
20 of 33
which may suggest?
ideas for possible future research if strongly related
21 of 33
are correlations slow and spenny?
nop
22 of 33
why?
no need for controlled env / no mainpulation
23 of 33
what kind of data can be used making less time-consuming?
secondary data from others

why?
bc lack experimental manip / ctrl
