prediction
the "things" that are changed in an experiment
variable

constant
the one "thing" a scientist changes in an experiment
independent variable
the "things" that change due to the independent variable
dependent variable
what axis does the independent variable go on?
x
what axis does the dependent variable go on?
y
an educated guess made before an experiment
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
a group actively participating in an experiment. getting a treatment
experimental group
gets no treatment or gets "normal treatment"
control group
a statement that summarizes exactly what happened in an experiment
conclusion
what does a chi square test?
the observed data with the expected data
what is the rule to accept a null hypothesis?
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

variable
the "things" that stay the same in an experiment
constant
the one thing a scientist manipulates in an experiment
independent variable
the "thing" that changes because of the independent variable
dependent variable
which axis does the independent variable go on?
x
which axis does the dependent variable go on?
y
an educated guess made before an experiment. answers the question or problem
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
a group actively participating in the experiment. they get a treatment
experimental group
gets no treatment or gets "normal treatment", not experimental treatment
control group
a statement that summarizes exactly what happened in an experiment
conclusion
what does a chi square test?
the observed data with the expected data
