A Poisson distribution has a double mode at x = 1 and x = 2. The probability for x = 1 or for x = 2 of these two values is:
For the study purpose, the mean of the observations is 148 gm and standard deviation is 17.4 gm. Approximately, the coefficient of variation equals to:
The mode of the given data set is 12. The sum of the frequency on both sides of mode are 16. The skewness:
The grouped data for the observations are
