RESEARCH METHODOLOGY

Detailed explanation-1: -The value of the number indicates the strengthof the relationship: r = 0 means there is no correlation. r = 1 means there is perfect positive correlation. r =-1 means there is a perfect negative correlation.

Detailed explanation-2: -When r = 1, it means that there is a perfect positive linear relationship between the variables, and all individuals sampled lie exactly on the line of best fit with a positive slope.

Detailed explanation-3: -A perfectly positive correlation means that 100% of the time, the variables in question move together by the exact same percentage and direction. A positive correlation can be seen between the demand for a product and the product’s associated price.

Detailed explanation-4: -Possible values of the correlation coefficient range from-1 to +1, with-1 indicating a perfectly linear negative, i.e., inverse, correlation (sloping downward) and +1 indicating a perfectly linear positive correlation (sloping upward).
