Correlations, Associations and Hypothesis Testing (with R)

In statistical analysis and machine learning, exploring and assessing the strength of associations between variables/features is crucial. Junior analysts as well as more experienced data scientists will benefit from this course. This course will help you build the right foundation at an early stage of your career if you are an aspiring/junior data analyst/scientist in particular. Furthermore, if you are a seasoned data scientist, this course will assist you in revisiting and ultimately improving your understanding of the evaluation of associations between variables/features.

The course is broken down into three sections. The first section examines how to assess and quantify relationships between numerical variables. The assessment of associations between categorical variables is the focus of the second section. The assessment of associations between numerical and categorical variables is covered in the third section. Each section examines a variety of statistical metrics in relation to variable associations before constructing statistical hypothesis tests to assess the strength of these relationships.

Throughout the course, there will be practical sessions where you will learn how to implement the methods discussed in the course (using R) and perform various hypothesis tests on real-world datasets. You'll also learn and master the art of interpreting data in a larger context. A quiz is also included at the end of each section. These quizzes are designed to assist you in consolidating the main concepts covered in the course. You will have a clear and coherent understanding of covariances, correlations, t-test, Chi-squared test, ANOVA, F-test, and much more by the end of the course. You'll learn when and how to use these tests, as well as how to ensure that the underlying assumptions are met.

• Anyone interested in data analysis.
• All levels

Requirements

• No prior experience is required. You will start from the basics.
