WebFeb 16, 2024 · The linear correlation coefficient is known as Pearson’s r or Pearson’s correlation coefficient. Which reflects the direction and strength of the linear relationship between the two variables x and y. It returns a value between -1 and +1. In this -1 indicates a strong negative correlation and +1 indicates a strong positive correlation. Web· A negative association in scatter plot means, if one variable increases, then another variable is decreases and similarly if one variable is decreases and other variable is increases. If it has strong negative correlation, then the data points are closer together and it forms better linear negative pattern.
