What are the 5 steps in hypothesis testing?
- Step 1: Specify the Null Hypothesis.
- Step 2: Specify the Alternative Hypothesis.
- Step 3: Set the Significance Level (a)
- Step 4: Calculate the Test Statistic and Corresponding P-Value.
- Step 5: Drawing a Conclusion.
What is the aim of hypothesis testing?
The purpose of hypothesis testing is to test whether the null hypothesis (there is no difference, no effect) can be rejected or approved. If the null hypothesis is rejected, then the research hypothesis can be accepted.
Why P value is important?
The p-value is the probability that the null hypothesis is true. A low p-value shows that the effect is large or that the result is of major theoretical, clinical or practical importance. A non-significant result, leading us not to reject the null hypothesis, is evidence that the null hypothesis is true.
