Preparing for university entrance exams requires a sharp understanding of research methods and data analysis. This course focuses on a critical concept in evidence-based education policy: the winner’s curse.
In education research, the most exciting results are often exaggerated. This happens because of statistical noise and measurement errors. By studying the winner’s curse, you will learn how to look past flashy headlines and understand the true impact of an educational intervention.
Throughout this course, you will build the analytical skills needed to succeed in your entrance exams. You will explore how latent effect sizes and underpowered trials skew data. You will also learn how to identify common measurement errors, such as order reversals and sign errors, and how to adjust for them.
The ultimate goal is to help you think critically like a researcher. By the end of this course, you will be able to evaluate research results accurately and apply these concepts directly to entrance exam practice questions.
