A correlation is a
non
experimental
Method to look for a
relationship
between
two
variables
To find a correlation,both Sets of data should be
plotted
against
eachother
on a
scattergram
This is a
strong
positive
correlation
This is a
strong
negative
correlation
This is a
weak
positive
correlation
This is a
weak
negative
correlation
A positive correlation is when one
variable
increases
as the other
increases
A
negative
correlation
is when one
variable
decreases
as the other
increases
A coefficient is a
number
representing the
strength
of
a
correlation
between
two
variables
A coefficient with a minus in front of it means that the
correlation
is
negative
A coefficient is always between
1
and
-1
The closer to zero a coefficient is, the
weaker
the
correlation
is
Correlation
does not mean
causation
