Linear Correlation
The correlation between two variables is said to be linear if the
change of one unit in one variable result in the corresponding change in the
other variable over the entire range of values.
The relationship between two variables is said to be non – linear if
corresponding to a unit change in one variable, the other variable does not
change at a constant rate but changes at a fluctuating rate. In such cases, if
the data is plotted on a graph sheet we will not get a straight line curve.
