Statistics is a mathematical science which deals with the collection of data, analyzing it, interpretation or explanation, and presentation of that data. The person who studies statistics in a detail are called as statisticians. The statisticians improve the quality of data by considering many types of experiments and by doing survey sampling.

Basically statistics came into origin in 1962 when the book called �Natural and Political Observations upon the bills of mortality� by John Graunt was published. The scope of this discipline of statistics became popular in the 19th century when people started to think systematically to obtain the solution of the given problem. They started collecting the data for a problem and analyzed it to obtain an optimum solution for that problem.

Practically to get the solution for a problem a little part of the problem called as the �sample� is studied and according to the results of that sample the data is compiled for entire group. That collected data is subjected to statistical analysis and it is interpreted and the solution is obtained. This concept is explained clearly by the statistics homework help.

Statistics is mainly divided into descriptive statistics, inferential statistics and mathematical statistics.

Descriptive statistics gives the summary of the population data by describing what ever observations were made either numerically or graphically. The values obtained are solved using suitable formulas or they are plotted in a graph with a proper scale on x and y axes.

Inferential statistics uses the patterns in the data sample to draw the inferences of the given population. Randomness is checked in this method. These inferences may be used as answers in the form of yes or no for the data. This process is called hypothesis testing. After this the estimating of numerical characteristics of data is done by the method of estimation. After estimation correlation process is applied. Many modeling techniques are used for the obtained data like regression, extrapolation, and interpolation are applied. In contrast to these there are other types of modeling techniques like ANOVA, data mining, time series etc.

Mathematical statistics deals with the theoretical basis of statistics. Mathematical statistics is also known as statistical theory. The basic type of mathematical concept employed to understand the randomness is probability. Mathematical statistics is a branch of applied mathematics which uses probability theory and analysis to understand the theoretical side of statistics. This mathematical statistics holds good only to the problems which satisfies the mathematical assumptions made by the system.

Statistics is in fact a very difficult subject for which detailed study is very important to obtain an optimal solution. Hence statistics homework help provides that detailed description about the important concepts of statistics.
