WebbThe correlation measures linear relationship. In informal context relationship means something stable. When we calculate the sample correlation for stationary variables and … WebbA (Pearson) correlation is a number between -1 and +1 that indicates to what extent 2 quantitative variables are linearly related. It's best understood by looking at some scatterplots. In short, a correlation of -1 indicates a perfect linear descending relation: higher scores on one variable imply lower scores on the other variable.
