Statistics is the method of gathering, arranging, and explaining the data presented. It retrieves information from a study of a large quantity and presents facts, which can make things clear and understandable for the average person.

This course has taught me that these statistics can involve the following, hypothesis development and testing, selection of appropriate statistical tests, and evaluating statistical results.
Furthermore, function of statistics is presentation of fact, simplification of complexities, facilitating comparisons, facilitating the formulation of policies, widening of human knowledge, useful in testing the laws of other sciences, facilitates the forecasting, establishment of correlation between two facts. ( Madan kumar, 2014) Statistics provided methodology for understand, assessed and controlled the operation of the organization and thus promotes organization welfare.

According to Florence Nightingale statistics is considered to be the most important science in the world as every other science from a social, political and educational perspective is dependent on it (Ridgeway, Nicholson & McCuster, 2007, p. 44). Statistical methods is a subject that organizes information and provides the necessary means for all other disciplines to deal with this particular information by taking the issue of variability into consideration. It therefore forms an essential part of most studies in the academic sphere (Coetzee & van der Merwe, 2010, p. 1). The objective of this methodological discipline is to provide students with the fundamental knowledge and skills to have an understanding of research to subsequently review

During this period, I got to know that Statistics is an extremely interesting and useful field as it is a means of understanding the world. Statistics is much closer to our life. We use data to analyze different views which are likely to lead to an informed decision. For example, a doctor may
I would not have not spent my whole day exploring the computer and the internet. Videogames would have not been invented and would have changed my life drastically.

In terms of statistics, descriptive statistics also includes details of data such as its mean, standard deviation, variance etc. Such details help to understand the nature of data. b) Predictive analytics is the most widely used form of analytics. It uses data analysis techniques such as predictive algorithms to predict what is about to happen next. Its advantages in planning ahead for future possibilities has made it a popular technique in many organizations, especially in field of consumer behavior.
