Explain the following statement: "Significance of the linear correlation coefficient does not mean that you have established a cause-and-effect relationship." You find that the correlation coefficient of a study is 0.7 with a p-value of 0.003. What should you do?
A correlation coefficient is used in statistics to describe a pattern or relationship between two variables. Anegative correlationdescribes the extent to which two variables move in opposite directions. An increase in X is associated with a decrease in Y for two variables, X and Y. A negative c...
In simple linear regression analysis, the coefficient of correlation (or correlation coefficient) is a statistic which indicates an association between the independent variable and the dependent variable. The coefficient of correlation is represented by “r” and it has a range of -1.00 to +1.00. ...
Interpretation of the correlation coefficient. The correlation coefficient measures the strength of a linear relationship between two variables. The correlation coefficient is always between -1 and +1. The closer the correlation is to +/-1, the closer to a perfect linear relationship. Here is how...
A correlation coefficient is the statistical measure that will tell us whether there is a relationship between our two variables of interest, and if there is one, how strong that relationship is. The value of the correlation coefficient, ϝ (rho), ranges from -1 to +1. The closer to -...

The linear correlation coefficient is a calculated number for the given graph data that measures the strength of the relationship between the two for... Learn more about this topic: The Relationship Between Variables: Correlation Coefficient & Scatterplots ...
It means the positive of negative of r and b is the same.(3) The hypothesis testing for β and ρ is of the same meaning. It means we only need to do one;(4) The normal distribution is the condition of linear correlation and regression....
