This free online explains the concepts of hypothesis testing as it is used for assumptions in populations parameters.
Description
Data analytics and hypothesis testing is an aspect of inferential statistics that enables us to make decisions about populations based on available samples. This free online course on Alison takes you through the concept of population mean and population proportion. The course defines the steps used in computing the population value and how the critical value approach is implemented in two-tailed hypothesis testing.
The course explains the different types of errors encountered in hypothesis testing. You will learn about the several ways of obtaining the value of null hypothesis as well as the relationship between hypothesis testing and decision making. You will learn how the hypothesis tests are used for two population means. You will also get to know more about how to make inferences on the differences between two population means.
Regression analysis is a statistical technique that is very useful in engineering and science problems. This free online course explains how empirical models are used for process optimization, such as finding the level of temperature that maximizes yield and process control purposes. You will study factorial experiments and various environmental studies in businesses. Start this course on Alison today and improve your skills on data analytics.
