Steps and Confidence Intervals in Hypothesis Testing
Steps in Hypothesis Testing
- You want to select the alpha level before you calculate the probability value. You compare your probability value to your previously-selected alpha level when deciding whether or not you can reject the null hypothesis.
- Researchers generally specify a null hypothesis that is the opposite of what they are predicting. Getting a value lower than the alpha level allows you to reject the null hypothesis, but getting a value greater than the alpha level does not prove that the null hypothesis is true.
