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...
ThePearson correlation coefficient (r)is the most common way of measuring a linear correlation. It is a number between –1 and 1 that measures the strength and direction of the relationship between two variables. Pearson correlation coefficient (r)Correlation typeInterpretationExample ...
In anegative correlation, two variables move in opposite directions. Increasing one variable decreases the other. The correlation coefficient is a negative number between 0 and -1. There iszero correlationif the data points are all over the graph instead of forming a straight line. The correlation...
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 I tend to interpret correlations. -1.0 to...

Once correlation coefficient is a number from -1 to 1, or any number in-between. If two data sets move in lock step in the same direction and by the same amount, they have a correlation coefficient of 1. If they move by the exact same amount but in the opposite direction, the number...
A correlation coefficient greater than zero indicates a positive relationship while a value less than zero signifies a negative relationship. A value close to zero indicates a weak relationship between the two variables being compared. A negative, or inverse, correlation is a key concept in ...
The Correlation Coefficient is a widely used method of determining the strength of the relationship between two numbers or two sets of numbers. This coefficient is calculated as a number between -1 and 1. 1 being the strongest possible positive correlation and -1 being the strongest possible nega...
The correlation coefficient is a unitless number and must always lie between -1.0 and +1.0, inclusive. True or False?CorrelationThere is a difference in correlation and causation. When two variables are correlated, it means that as one changes in value...
The correlation coefficient is a statistical measure of the strength of the relationship between two data variables.
