I was reading a blog on correlation coefficient. It is as stated below
" For example, suppose a study is conducted to assess the relationship between outside temperature and heating bills. The study concludes that there is a negative correlation between the prices of heating bills and the outdoor temperature. The correlation coefficient is calculated to be -0.96. This strong negative correlation signifies that as the temperature decreases outside, the prices of heating bills increase and vice versa"
Here as temp decreases price of heating bill increases but in vice versa if prices of heat bills decreases temp wont shoot up right. Then how can we capture this?
