Question

Which of the statements below are true? Select all that apply. A correlation of r = .92 indicates a strong, positive correlation. Correlation must be between 0 and 1. A correlation of r = -.17 indicates a strong, negative correlation. A correlation of r = .01 means there is no significant correlation. Correlation must be between -1 and 1. Correlation is a numeric measure of the strength and the direction between two categorical variables.

Answer 1

Answer with explanation:

Correlation Coefficient (r) ,measures the relation between two variables written in the form of ordered pair.

→If ordered pair (x,y) represents two variables , correlated with each other

that is with increase in x, y also increases, or vice versa ,then r would be positive.

And if , with increase in x, y decreases or vice versa, then r will be negative.

→ -1 ≤ r ≤1.

The Correct statements are

1. →A correlation of r = .92 indicates a strong, positive correlation.

4.→A correlation of r = .01 means there is no significant correlation.

5.→ Correlation must be between -1 and 1.

6.→Correlation is a numeric measure of the strength and the direction between two categorical variables.

Answer 2

The correct answer for the question that is being presented above is this one: "Correlation must be between 0 and 1; A correlation of r = .01 means there is no significant correlation; Correlation must be between -1 and 1; Correlation is a numeric measure of the strength and the direction between two categorical variables."
