Biochemical Oxygen Demand (BOD) may not be a good index for pollution for water bodies receiving effluents from

List the events that reduce the biological oxygen demand (Bod) of a promary effluent during sewage treatment .

Median of a distribution is the value of the variable which divides it into equal parts . In case of individual observations x_1,x_2 .. x_n , if the number of observations is odd, then median is the value of ((n+1)/2) th observation when the observations have been arranged in ascending or descending order of magnitude. In case of even number of observations median is the A.M. of the values of (n/2) th and (n/2+1) th observations, arranged in ascending or descending order of magnitude . The mode of distribution is that value of the variable for which the frequency is maximum . The mode of following series is {:("value (x)",40,44,48,52,56,62,64,72,76),("frequency (f)",10,12,14,20,15,19,18,8,4):}
