Question

what is a correlation ?

Answer 1

its on a graph ?
but like I don't now what it means

Answer 2

What type of correlation is shown in the graph?

Answer 3

Correlation is a concept from elementary statistics.
The commonest is linear correlation, where we determine whether the dependent variable, y, is linearly dependent on the independent variable, x.
Let me take a look at your graph; then I could give you more specific feedback.

Answer 4

In looking at your graph, I'll try to determine whether the data points appear to lie pretty much in a straight line. I'll also determine whether y increases as x increases, or decreases when x increases. You going to be able to post that graph?
