negative correlation meaning

A perfect negative correlation means the relationship that exists between two variables is exactly opposite all of the time. The square of the correlation coefficient (generally denoted by "R2", or R-squared) represents the degree or extent to which the variance of one variable is related to the variance of the second variable, and is typically expressed in percentage terms.

A weak positive (upward sloping) linear relationship, +0.50. These variables move in opposite directions from each other and the correlation between them can vary drastically over a set period of time. A positive correlation coefficient would be the relationship between temperature and ice cream sales; as temperature increases, so too do ice cream sales.
