Can you have a negative correlation
WebNegative r values indicate a negative correlation, where the values of one variable tend to increase when the values of the other variable decrease. The p-value gives us evidence that we can meaningfully conclude that the population correlation coefficient is likely different from zero, based on what we observe from the sample. WebNegative correlation can be described by the correlation coefficient when the value of this correlation is between 0 and -1. The amount of a perfect negative correlation is -1. The strength of the correlation between the …
