WebFeb 8, 2024 · A positive correlation is a relationship between two variables in which both variables move in the same direction. Therefore, when one variable increases as the other variable increases or one variable decreases while the other decreases. An example of a positive correlation would be height and weight. Taller people tend to be heavier. WebThe Sig (2-tailed) p-value tells you if your correlation was significant at a chosen alpha level. The p-value is the probability you would see a given r-value by chance alone. If your p-value is small, then the correlation is significant. Parallel Design / Parallel Group Study.
