The correlation for the values of two variables moving in the opposite direction isa.Positiveb.Negativec.Non-lineard.LinearClear my choice

The correlation coefficient describes:a.Magnitudeb.Directionc.Both magnitude and directiond.None of theseClear my choice

Assertion (A) Broadly, there only two types of correlation i.e., positive and negative.Reason (R) The correlation is said to be positive when the variables move together in the same direction, the correlation is negative when they move in opposite directions.

Which of the following are measured by correlation coefficienta.Linear association between two random variablesb.Direction of relationship between two variables (positive or negative association)c.A unit free value for the strength of linear relationship between two random variablesd.All of the above

What does a positive covariance between two variables indicate?Question 1Answera.Variables move in opposite directionsb.There is no relationship between variablesc.One variable is constantd.Variables move together in the same direction

As x increases, y decreases. positive correlation negative correlation no correlation correlation coefficient
