The correlation coefficient is –1. b. The correlation coefficient is 0. c. The correlation coefficient is 1. d. The coefficient of determination is between –2 and 2. 21 In a simple linear regression problem, the least squares line is = 2.73 - 1.02 , and the coefficient of determination is 0.7744. The correlation coefficient must be –0.88 ...

A Negative correlation coefficient means that as one variable increases, the other decreases (i.e., an inverse relationship). Regardless of the strength of the relationship, correlations cannot tell us that one variable CAUSES changes in the other because: 1) Variable X could be affecting variable Y OR variable Y could be affecting variable X ...

A correlation coefficient of -1 means a perfect negative correlation, or that X and Y move in exactly opposite linear directions. A zero correlation means that X and Y are not linearly related. The correlation coefficient measures the degree and direction of the linear relation between two random variables.

If all the data fall exactly on the fitted line, r2=1. The coefficient of determination will lie beween 0 and 1. Coefficient of Correlation (r) The coefficient of correlation is a measure of the strength of the linear association between Y and X. It will always be the same sign as the slope estimate (b1), but it has several advantages:

25. Professor Henley calculated a squared multiple correlation coefficient. It was .36. This means that . a. 36% of the variance in the final score was explained. b. 60% of the variance in the final score was explained. c. 6% of the variance in the final score was explained. d. 13% of the variance in the final score was explained. e.

A correlation of -1 means that there is a perfect negative linear relationship between variables. The scatterplot shown below depicts a negative relationship. It is a negative relationship because high scores on the X-axis are associated with low scores on the Y-axis. A correlation of 0 means there is no linear relationship between the two ...

A correlation coefficient ( ) of +1.0 means that the two variables move up and down in perfect synchronization, while a coefficient of -1.0 means the variables always move in opposite directions. A correlation coefficient of zero suggests that the two variables are not related to one another; that is, they are independent. j.

The appropriate correlation coefficient depends on the scales of measurement of the two variables being correlated. There are two assumptions underlying the significance test associated with a Pearson correlation coefficient between two variables. Assumption 1: The variables are bivariately normally distributed.

1. The Pearson Correlation Coefficient. Correlation. In statistics, the word "correlation" has a very specific meaning. Statistical correlation means that, given two variables X and Y measured for each case in a sample, variation in X corresponds (or does not correspond) to variation in Y, and vice versa.

The coefficient of determination is a number between 0 and 1, inclusive. That is, If r2 = 0, the least squares regression line has no explanatory value. If r2 = 1, the least-squares regression line explains 100% of the variation in the response variable.

If you wish to compare the correlation between one pair of variables with that between a second (nonoverlapping) pair of variables, read the article by T. E. Raghunathan , R. Rosenthal, and D. B. Rubin (Comparing correlated but nonoverlapping correlations, Psychological Methods, 1996, 1, 178-183).
