Question

in your own words, explain what a correlation is and when we would need to use one.What type of result would give us a strong relationship? What kind of result would give us a weak relationship?

Definition Definition Relationship between two independent variables. A correlation tells the degree to which variables move in relation to each other. When two sets of data are related to each other, there is a correlation between them.
