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.

Correlation can either be positive or negative but it is a linear relationship. The larger the absolute value the stronger the relationship and we evaluate it through comparison of the extreme values of 0 and 1Question 3Answera.Falseb.True

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

Which of the following statements is TRUE?Only a correlation equal to 0 implies causation.A correlation of 1 or -1 implies causation. If the two variables of a scatterplot are strongly related, this condition implies causation between the two variables.A high correlation is insufficient to establish causation on its own.
