Can a weak correlation be significant
WebThere are three ways to describe the correlation between variables. Positive correlation: As x x increases, y y increases. Negative correlation: As x x increases, y y decreases. No correlation: As x x increases, y y … WebApr 2, 2024 · If the test concludes that the correlation coefficient is significantly different from zero, we say that the correlation coefficient is "significant." Conclusion: There is sufficient evidence to conclude that there is a significant linear relationship between x and y because the correlation coefficient is significantly different from zero.
