FAQs: Clearing Your Doubts about R Value
What does an R value of 1 mean? An R value of 1 signifies a perfect positive linear relationship between two variables. As one variable increases, the other increases proportionally.
Can the R value be negative? Yes, the R value can be negative, indicating a negative linear relationship. As one variable increases, the other decreases.
How is R value different from R2? While both R and R2 measure correlation, R focuses on the strength and direction of the linear relationship, while R2 represents the proportion of variance explained by the relationship.
Is a high R value always good? A high R value indicates a strong linear relationship, but its goodness depends on the context. Correlation does not imply causation, so a high R value may not always be meaningful.
Can the R value be used for non-linear relationships? The R value is specifically designed for linear relationships. For non-linear correlations, other correlation coefficients, like the Spearman rank correlation coefficient, may be more appropriate.
How does sample size affect the R value? Smaller sample sizes may result in less reliable R values. Larger sample sizes generally provide more accurate representations of the true population correlation.
