If the values of two variables move in the same direction, then the correlation is said to be __________a.Non-linearb.Linearc.Positived.NegativeClear 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.

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

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

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

Which statement about correlation is FALSE?The correlation of a data set can be positive, negative, or 0.Correlation is used to define the variables of only non-linearly related data sets.Correlation between the variables of the data set can be measured.Correlation is the degree to which the two variables of a data set resemble each other.
