RESEARCH METHODOLOGY

Detailed explanation-1: -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).

Detailed explanation-2: -Positive Correlation vs Negative Correlation For example, if one stock increases and another increases, that is a positive correlation. A negative correlation. For example, when an independent variable increases, the dependent variable decreases, and vice versa.

Detailed explanation-3: -A negative correlation indicates two variables that tend to move in opposite directions. A correlation coefficient of-0.8 or lower indicates a strong negative relationship, while a coefficient of-0.3 or lower indicates a very weak one.

Detailed explanation-4: -The correlation coefficient is measured on a scale that varies from + 1 through 0 to – 1. Complete correlation between two variables is expressed by either + 1 or-1. When one variable increases as the other increases the correlation is positive; when one decreases as the other increases it is negative.
