Part 1

Choose the correct answer below.

The correlation between variables must be an x-value of a point on the graph.

The correlation between variables must be a y-value of a point on the graph.

The correlation between variables must be significant.

The correlation between variables must be greater than zero.

Definition Definition Statistical measure used to assess the strength and direction of relationships between two variables. Correlation coefficients range between -1 and 1. A coefficient value of 0 indicates that there is no relationship between the variables, whereas a -1 or 1 indicates that there is a perfect negative or positive correlation.
