Generally people consider statistics to be a mathematical science pertaining to the collection, analysis interpretation or explanation and presentation of data while statistician considers it a branch of mathematics concerned with collecting and interpreting data. Because of its empirical roots and its focus on applications, statistics is usually considered to be a distinct mathematical science rather than a branch of mathematics. Statistical methods can be used to summarize or describe a collection of data this is called descriptive statistics. This is useful in research, when communicating the results of experiments. In addition, patterns in the data may be modeled in a way that accounts for randomness and uncertainty in the observations and are then used to draw inferences about the process or population being studied; this is called inferential statistics. Inference is a vital element of scientific advance, since it provides a prediction (based in data) for where a theory logically leads.

The present book has been written in a lucid style using simple language that a layman may understand it easily. The book has been written after a detailed study of concepts and assumptions of subject matter.
