(a) The Coefficient of Correlation is independent of change of origin and scale. (b) The Coefficient of Correlation between the two variables is the arithmetic average of the two Regression Coefficients. (c) The probable error of the Coefficient Correlation is 0.6745 times of its standard error. (d) Coefficient of Correlation multiplied by the ratio between […]

Statement (I): The probability of the joint occurrence of independent events A and B is equal to the probability of A multiplied by the probability of B or vice versa. Statement (II): The probability of the joint occurrence of independent event A and dependent event B is equal to the probability of event A multiplied by the […]

Statement – II : When a sampling distribution of mean is prepared by taking small sized samples from a normally distributed population, the distribution takes the shape of normal distribution.

Statement – II : The product of coefficient of correlation between X and Y variables and the ratio between standard deviation of X variable to standard deviation of Y variable measures the slope of the regression line of X on Y variable.
