Objectives of Statistics

The Objectives of Statistics:

The main objective of statistics is to study the various facts and problems in the research field and to evaluate the causes and results of the changes occurring in them.

Statistics is the science of gaining knowledge from data. You can collect data in the correct manner, perform detailed analyses, and effectively present the results if you have statistical knowledge.

Statistics teaches people how to make intelligent and accurate conclusions about a larger population by analysing a small and limited sample of data. The following are the major objectives of statistics:

• To draw conclusions (inferences) about a population followed by an analysis of information contained in sample data. This includes assessing the degree of uncertainty in these inferences.

• To plan the process and the extent of sampling so that the observations can be used to draw valid conclusions.

• To determine the type and quantity of data that must be collected.

• To organise and summarise the information.

• To analyse and draw conclusions from the data.

• To assess the conclusions’ strengths and evaluate their uncertainty.

According to Prof. Boddington, “The main objective of statistical research is to enable comparison between past and present results to ascertain the reasons for changes, which have taken place and the effect of such changes in future.

According to Johnson and Jackson, “The real purpose of statistical methods is to make proper sense out of facts and figures, to make discoveries about unknown and to cost light upon the situation.”

According to Robert W. Buges, “The fundamental principle of statistics is to remove the domain of ignorance, prejudice, rule of thumb, arbitrary and premature decisions, traditions and dogmatism and to increase the domain where decisions are made and principles are formulated on the basis of analysed quantitative facts.”

Hence, it is clear that statistics is an integral stage of national development, which helps us in solving various complex problems.
