measurement scale must be somewhat reliable in order to be valid
they are completely unrelated

An assesses whether the means of several groups are all equal to or different from each other
What are the three categories of research design?
experimental
quasi experimental
non experimental
are a sample of a larger population of levels
is used when there is more than one response variable
are chosen for their specific level/type.
measures the strength of the phenomenon
have many levels of a particular thing such as faces or accidents.
is the idea that you want to define your variables in specific testable terms and clarify exactly what you mean by a behavior.
3 qualities of a good hypothesis:
testable
falsifiable
succient: to the point and simple
multidirectional
A true experiment always uses
manipulation
control
a good hypothesis
One of the problems with is that they have a high chance of the third variable problem that the groups they are comparing are fundamentally different in some way.
design compares two or more groups on a variable of interest, but those groups vary in some important way.
