ECA003 Data Analysis Lecture 5 (cont.) Test of Hypothesis (Chapter 5) Dr Simona Rasciute E-mail: [email protected]
Hypothesis testing is based on the idea that we can say things about the population from a sample taken from it
Steps of Hypothesis Testing 1. Decide on your hypothesis (provide evidence for alternative hypothesis): a. The hypotheses is always about the population parameters, not the sample values or statistics. b. The null hypothesis usually refers to the status quo- the things we are trying to find evidence against. It generally represents no effect. c. A null hypothesis should include a statement of equality and the alternative should not.
