Often the binomial distribution’s cumulative density function is used, which gives the probability of having x or less successes in n trials. Calculating this probability is simple for a small n, but becomes tedious as n gets large, because of the binomial coefficient. The binomial coefficient ...
A probability distribution is an indispensable means of coping with reality. It is when sifting through uncertain situations that probability distributions lend themselves to well-saved decisions. Money will be another example: probability distributions work as compasses to slot into the investment land, ...

A correlation coefficient is the statistical measure that will tell us whether there is a relationship between our two variables of interest, and if there is one, how strong that relationship is. The value of the correlation coefficient, ϝ (rho), ranges from -1 to +1. The closer to -...
In statistics, we are involved in the distribution of data. This distribution of data may better help us to analyse the given data under the data analysis. Apart from statistics, data distribution is done in the field of engineering, business, science, etc....
Pearson coefficient is a type of correlation coefficient that represents the relationship between two variables that are measured on the same interval.
