“TYPE:- There are three types of correlation that are identified:
1. Positive correlation:- Positive correlation between two variables is when an increase in one variable lead to an increase in the other and decrease in one leads to a decreases in the other.
2. Negative correlation:- Negative correlation is when an increase in one variables leads to a decreases in another and vice versa.
3. No correlation:- Two variables are uncorrelated when a change in one doesn’t lads to a change in the other and vice versa.
“A correlation coefficient is usually used during a co-relation study. It varies between +1 and -1 value close to +1 indicates a strong positive correlation while a value close to -1 indicates strong negative correlation.”
