It is the one that uses various quantitative tools for gathering and evaluating large sets of data. Statistics is an efficient tool that helps businesses in making efficient and well-informed decisions. It is used in various fields such as economics, science, medicine, marketing, psychology, and politics. Statistics helps in converting the acquired raw data into key information which is helpful for developing a better understanding and sound decision making. Business with the application of statistical tools is able to make a better plan by making accurate assumptions and predictions. They are able to handle future uncertainties in a better way by predicting cyclical and general economic fluctuations. Statistics is classified into two categories that are descriptive and inferential statistics. Types of Statistics Descriptive Statistics Descriptive statistics is the first stage in statistical analysis. It is concerned with acquiring data and presenting it. Descriptive statistics involves the use of charts, tables, graphs, or other statistical tools for summarizing a given set of data. Various calculations included under this are measures of central tendency and variability. Inferential Statistics It is one that checks the validity of generalizations made by descriptive statistics. Inferential statistics enable the statisticians to draw conclusions and make decisions and predictions by evaluating the collected information. It is used for reading the data and making the right estimates from a sample of information collected. This uses various techniques such as regression analysis, correlation analysis, analysis of variance, and covariance.

Limitations of Statistics Ignores qualitative aspects Statistics considers only the quantitative aspects for analysis purposes. It takes into account those units which can be measured or numerically expressed. Qualitative aspects like intelligence, efficiency, poverty, and honesty are ignored and not studied under it. No exact statistical laws There are no exact laws for statistics, unlike physical sciences and mathematics. Statistical laws are only the appropriations and conclusions drawn by statistical methods are true only on an average under particular conditions. Requires statistics expert Another major drawback is that it requires an expert possessing high knowledge of statistics for using statistical methods. Employing an inefficient or untrained person may be quite dangerous and lead to false conclusions. Not applicable to heterogeneous data Statistics tools evaluate and analyses only the homogeneous set of data. It cannot be used to study and find relationships between varied patterns of data. Reveal only average results Results yielded by statistical methods are not universally true and only provide the average behavior. They came out to be true on an average under certain conditions.
