Study statistics to be better at research, more effective as a planner or more profitable in business

Statistics is a very useful thing to learn. Statistical data is used in many professions; more than what you might think. A knowledge of statistics not only helps you collect and compile statistics; but it also enables you to better understand their relevance and application whether in business, research or day to day situations ranging from predicting the weather to determining what you should invest your money in.

  • Describe and apply the concept of Non Parametric Statistics.

There are different types of statistics

Descriptive statistics describe a set of data, while inferential statistics make inferences about large groups based on data from a smaller subset of the group.  To infer means to draw a conclusion based on facts or premises.  Thus an inference is the end result; a proposition based on the act of inferring.

Understanding how to gather and analyze statistics is the starting point for using statistical data in real world situations, to make better decisions for planning and management, at work, play or in any other aspect of your life.

When you comprehend these things, you will understand how statistics is something that can make your life better, wherever you live, and whatever you do.
