hypothesis
used as a basis of accepting or rejecting the hypothesis
null hypothesis
a group that gets a fake treatment without knowing it.
placebo group

experimental group
gets no treatment or gets "normal treatment"
control group

conclusion
what does a chi square test?
the observed data with the expected data

if the x^2 is less than the critical value
what is the rule to reject a null hypothesis?
if the x^2 is more than the critical value

placebo group
a group actively participating in the experiment. they get a treatment
experimental group
gets no treatment or gets "normal treatment", not experimental treatment
