Causation, correlation...
A Bar Graph!
That's exactly what the equation tells you.
An advantage of using a correlational study is that it allows you to investigate variables that cannot be directly manipulated.
A variable is a number that isn't fixed, it can be anything. So in this situation x and y are the variables.
Time and temperature
Variable are used to show relationships by multiple ways.
an equation
Direct or inverse relationships,that is a problem
Causation, correlation...
An intervening variable is a hypothetical internal state that is used to explain relationships between observed variables
There are complex models that allow researchers to study several variables if the experiment is carefully designed and very carefully carried out. These models can show whether a variety of variable interactions occur, and if that is your focus then these models are good. But the best experiments investigate a small number of variables, as few as one.

I don't think it's a graph..
Correlational
They can do.
