ACKNOWLEDGEMENT –

First and foremost we like to thank our supervisor of the project Mrs Sujatha V. for her valuable guidance an advice. She inspired us greatly to work in this project. Her willingness to motivate us contributed majorly in this project. We also would like to thank her for showing us some example that related to our project.

Besides, we would also like to thank VIT University for providing us with a good environment and facilities to complete this project. Also, we would like to thank school of computer science (SCSE) of VIT University, for offering this subject and computing project. It has given us the opportunity to participate and learn about various methods of calculating statistical distribution.

Finally, an honourable mention goes to my team for completing this project. Without helps of particular mentioned above, we would have faced many difficulties while doing this project.

INTRODUCTION
INTRODUCTION

In statistics, dependence refers to any statistical relationship between two random variables or two sets of data. Correlation refers to any of a broad class of statistical relationships involving dependence.

Familiar examples of dependent phenomena include the correlation between the physical statures of parents and their offspring, and the correlation between the demand for a product and its price. Correlations are useful because they can indicate a predictive relationship that can be exploited in practice. For example, an electrical utility may produce less power on a mild day based on the correlation between electricity demand and weather. In this example there is a causal relationship, because extreme weather causes people to use more electricity for heating or cooling; however, statistical dependence is not sufficient to demonstrate the presence of such a causal relationship (i.e., Correlation does not imply causation).

In this project though we show computation of several distribution techniques. The program allows computing several distributions that are 1. Binomial distribution
2. Poisson distribution
3. Normal distribution
4. Normal distribution (2 variables)
5. Chi-square distribution
6. Student T distribution

BINOMIAL DISTRIBUTION –
 The binomial distribution is the discrete probability distribution of the number of successes in a sequence of n independent yes/no experiments, each of which yields success...
