Learn Statistics in Detail, Master all concepts of statistics through practice.
Statistics is the science of collecting, analyzing and making inference from data. Statistics is a particularly useful branch of mathematics that is not only studied theoretically by advanced mathematicians but one that is used by researchers in many fields to organize, analyze, and summarize data. Statistical methods and analyses are often used to communicate research findings and to support hypotheses and give credibility to research methodology and conclusions. It is important for researchers and also consumers of research to understand statistics so that they can be informed, evaluate the credibility and usefulness of information, and make appropriate decisions.
Statistics is an emergent discipline that has rapidly adapted to current challenges.In today’s era of big data — where the computer and network are everywhere and everything can be measured — you need statistics to make that data useful.
To learn how a process behaves, you need to conduct experiments. And now we have ways of designing those experiments so that you learn the most from a limited number of experimental runs.To estimate the models, you need tools to refine and validate the models, and the state of the art has much improved for this in the last few years.Also we have much better tools to use the models to optimize processes and make them robust with respect to variation.
Statistics must be used responsibly. You need good data, and enough of it. Controlled experimental data is best. Selection and confounding biases can easily corrupt the analysis if you don’t pay attention to the process that created the data. When you go about doing statistics yourself, you need to learn the problems that can happen. You need to think through the analysis carefully.
Some of us learn statistics as part of our education. Some of us learn on the job. Some of us still have a lot to learn. Let’s begin learning all concepts of probability and statistics through this course.
