Detailed explanation-1: -The coefficient of correlation is of three types: positive, negative, and zero. It indicates that as the value of one variable (X) increases, the value of the other variable (Y) will also increase. Similarly, when variable X decreases, a decrease in Y too will take place.
Detailed explanation-2: -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. Complete absence of correlation is represented by 0.
Detailed explanation-3: -Strong positive linear relationship; as X increases in value, Y increases in value also; or as X decreases in value, Y decreases also.
Detailed explanation-4: -If the y value increases as the x value increases, the correlation is called positive correlation.
Detailed explanation-5: -A positive correlation is a relationship between two variables that move in tandem-that is, in the same direction. A positive correlation exists when one variable decreases as the other variable decreases, or one variable increases while the other increases.
