WebIf all points in a scatterplot of a data set lie exactly on a downward-sloping line, what is the correlation coefficient? The correlation coefficient is r=-1 . The correlation coefficient is r=-0. The correlation coefficient is r=+1. The correlation coefficient is r=-0.50. The correlation coefficient is r=-1. Fill in the blank. WebAnswer: True Difficulty: Easy Bloom’s: Knowledge A-Head: Definition of the Simple Regression Model BUSPROG: Feedback: A natural measure of the association between two random variables is the correlation coefficient. The sample covariance between the regressors and the Ordinary Least Square (OLS) residuals is always positive.

WebII: If the slope of the regression line is negative, then the linear correlation coefficient is negative. III: The value of the linear correlation coefficient always lies between −1 … WebJan 27, 2009 · A correlation coefficient is a value between -1 and 1 that shows how close of a good fit the regression line is. For example a regular line has a correlation coefficient of 1. A regression is a best fit and therefore has a correlation coefficient close to one. the closer to one the more accurate the line is to a non regression line.
The value of the correlation coefficient always ranges between 1 and -1, and you treat it as a general indicator of the strength of the relationship between variables. The signof the coefficient reflects whether the variables change in the same or opposite directions: a positive value means the variables change together in … See more In correlational research, you investigate whether changes in one variable are associated with changes in other variables. After data … See more The correlation coefficient tells you how closely your data fit on a line. If you have a linear relationship, you’ll draw a straight line of best fit that takes all of your data points into account on a scatter plot. The closer your points … See more The Pearson’s product-moment correlation coefficient, also known as Pearson’s r, describes the linear relationship between two quantitative variables.
