1. Why do experiments need random assignment to condition?

Back

participants have an equal chance to be in any condition

this equates groups on individual difference like demographics, background, and personality

Front

how does an experiment work?

Back

the experiment group is similar to the control group en every way, except for the presence of the independent variable

the two groups are similar because of randomly assigning participants to conditions

after exposure to the IV, you compare the two groups using the DV

then... any significant differences between groups on the DV can be attributed to the IV
