Any point in the Zao River section in biostratigraphic Unit V can be correlated 

 with the corresponding point in the Rakhi Nala section by means of Equation (1). 

 Similarly any point in the Rakhi Nala section can be correlated with the correspond- 

 ing point in the Zao River section by using Equation (2). 



The Coefficient of Correlation is expressed by the formula : 



r = y/bi x b 2 



By substituting the values b x and b 2 , we get 



r = Vo-445 1 x 1*9433 



= V * 86 49 

 = 0-930 



This high value of r is above the 99% confidence level.

When the two straight lines given by Equations (1) and (2) are drawn on a graph, 

 they intersect one another at an angle of 3 . Since the Rakhi Nala section has been 

 regarded as the standard section, therefore, for practical purposes only one straight
