Correlation coefficients range from -1.0 (a perfect negative correlation) to positive 1.0 (a perfect positive correlation). The closer correlation coefficients get to -1.0 or 1.0, the stronger the correlation.

correlation – one variable increases as the other increases. An example of negative correlation would be the amount spent on gas and daily temperature, where the value of one variable increases as the other decreases. Pearson's correlation coefficient has a value between -1 (perfect negative correlation) and 1 (perfect positive correlation).
