Statistics is basically a mathematical science wherein data is first collected; then is analysed, an explanation/

interpretation is given and finally is converted into a presentation. The data quality is improvised by statisticians

and is important to know what information we should pay attention to, and what to do with these and how to use them. Knowledge leads to

good decision-making and spurs progress.

More and more researchers are using Bayesian methods as these are best suited to subjective qualities of research. In this approach, the focus

is on the probability of the hypothesis, given the data i.e. P (H|D) .The data is considered as fixed and hypotheses as random. This theorem

has been used extensively to calculate prior probabilities. In this approach, newly acquired data is combined with prior data to predict an

outcome. This paper deals with some interesting case studies which have used Bayes� theorem.
