Document Summary
We need to make sure whatever we think is the cause actually happened before the result. We do expect that whatever happens when there is a connection will happen more often than not if i flip the switch, the light goes on. Both of these can be seen in a lab, because we control the temporal precedence and we o see the immediate change. The third is harder, especially in real-life settings. Elimination of rival plausible explanation the thing we notice is the cause, not other variables or nuance. Internal validity: the extent to which differences observed in study can be attributed to the experiment- treatment, rather to other factors. = to what extent can we be sure that the change occurred because of the independent variable, and not because of a rival plausible explanation. History events occurring between the first and last measurement that could also account for the result. Maturation process within the research participant themselves.
