Statistical Methods
All progressive knowledge in the modern world tends to precision. Precision is obtained with the help of numbers. Consequently, the science which deals with numbers has a vital role to play in the development of our civilization. This science is statistics.
The word “statistics” is used in two senses: one, when used in the plural, refers to a series of connected figures, and the other, when used in the singular, relates, to that branch of applied mathematics which deals with the collection, classification and use of quantitative data.
Quite a large number of definitions have been given to statistics as a science. Different writes place emphasis on different aspects of the subject-matter of this science. One main reason for this disagreement has been the constant development of the scope of this science.
The collected statistical material which is influenced by numerous causes has to be rendered easily intelligible, if it is to be used as a basis for judgement or action. In exact sciences like physics and chemistry the experimenter tries to disentangle complex causes by taking into account only the one with which he is concerned and keeping others aside. He can control the conditions in his laboratory. But in other sciences this is not possible. The experimental method fails. Conditions are not within the control of the observer. He has to take the data as they occur. We have to make use of some other methods for achieving their end. These are the methods of statistics. In order to get a clear picture out of the confusing mass of data, the latter have to be systematically collected, classified, tabulated, summarized, compared and presented. These are called statistical methods. They constitute definite rules of procedure in handing groups of data. A proper study of these principles forms the subject-matter of the “science of statistics”.
