We should only find correlation between two variables if they are quantitative, the association is straight enough, and there are no outliers. Just because two variables have a relationship does not mean that changes in one variable cause changes in the other. A relationship between two variables can be negative, but that doesn't meanthat the relationship isn't strong. Confidentiality vs Anonymity: Whats the Difference? Correlation Analysis helps in determining the degree and direction of relationship between two variables. A low r2 means that only a small portion of the variability of one variable is explained by its relationship to the other variable; relationships with other variables are more likely to account for the variance in the variable. To use this formula, youll first rank the data from each variable separately from low to high: every datapoint gets a rank from first, second, or third, etc. Correlation coefficients summarize data and help you compare results between studies.
