Understanding Correlation. Choose the correct code for the following statements being correct or incorrect Statement I: The geometric mean of the two regression coefficients of X and Y variables gives the value of the coefficient of correlation. Statement II: If the population distribution is not normal and a sampling distribution of mean is prepared by taking small sized samples, the sampling distribution of mean is not normal.

The probable error of the coefficient of correlation r is calculated by which one of the following formulae? Which of the following statements is false? When value of correlation coefficient is one, the two regression lines coincide 2. The regression coefficients are independent of the change of origin and of scale 3.

The sign of the regression coefficients are always the same 4. The square of the coefficient of correlation is called coefficient of determination. The sum total of the values of two variables 'X' and 'Y' is equal for all the observations.

The value of the coefficient of correlation between 'X' and 'Y' is: 1. Zero No correlation 4. The scatterplots below show how different patterns of data produce different degrees of correlation. If you look in different statistics textbooks, you are likely to find different-looking but equivalent formulas for computing a correlation coefficient.

In this section, we present several formulas that you may encounter. The most common formula for computing a product-moment correlation coefficient r is given below. Product-moment correlation coefficient. The correlation r between two variables is:. Population correlation coefficient. The formula below uses sample means and sample standard deviations to compute a sample correlation coefficient r from sample data. Sample correlation coefficient.
