In this video, I talk about the different types of error in biostatistics and hypothesis testing. I explain both with the help of examples and tables. Then I go on to explain the concept of power in a study and how it depends on sample size, alpha and effect size. I explain this with examples too. Finally I have a practice question for the students to understand and make sense of the whole topic.
