How can you interpret the output of coefficient of correlation?
Correlation Coefficient = +1: A perfect positive relationship. Correlation Coefficient = 0.8: A fairly strong positive relationship. Correlation Coefficient = 0.6: A moderate positive relationship. Correlation Coefficient = 0: No relationship.
When interpreting a correlation coefficient it is important to look at?
It cannot be used with binary variables (those taking on a value of 0 or 1). When interpreting a correlation coefficient, it is important to look at: The magnitude of the correlation coefficient.

What does correlation coefficient actually represent?
The correlation coefficient describes how one variable moves in relation to another . A positive correlation indicates that the two move in the same direction, with a +1.0 correlation when they move in tandem. A negative correlation coefficient tells you that they instead move in opposite directions.
What is the formula of correlation coefficient?
Formula For the Correlation Coefficient is given by: Correlation Coefficient = Σ [(X – X m) * (Y – Y m)] / √ [Σ (X – X m) 2 * Σ (Y – Y m) 2] Where: X – Data points in Data set X. Y – Data points in Data set Y. X m – Mean of Data set X. Y m – Mean of Data set Y.
What are the uses of Pearson correlation coefficient?
The Pearson correlation coefficient is typically used for jointly normally distributed data (data that follow a bivariate normal distribution). For nonnormally distributed continuous data, for ordinal data, or for data with relevant outliers, a Spearman rank correlation can be used as a measure of a monotonic association.
