Hypothesis Testing Steps: Sequence Explained
The process of hypothesis testing involves a specific, logical sequence of steps to determine if a hypothesis about a population is supported by sample evidence.
Understanding the Hypothesis Testing Sequence
Let's break down the correct order for testing a hypothesis:
- (b) Making a formal statement regarding the assumption: This is the first crucial step, involving the clear definition of the null hypothesis ($H_0$) and the alternative hypothesis ($H_a$).
- (d) Selecting an appropriate level of significance: Next, you choose the significance level, often denoted by $\alpha$. This threshold determines how much evidence is needed to reject the null hypothesis. Common values are 0.05 or 0.01.
- (a) Selection of sample and computing appropriate value from sample data: After setting the significance level, you collect a random sample from the population and compute a test statistic using the sample data.
- (c) Calculation of probability: Based on the test statistic and the sampling distribution under the null hypothesis, you calculate the probability of observing your sample results (or more extreme results). This is often referred to as the p-value.
- (e) Comparing the probability: Finally, you compare the calculated probability (p-value) with the chosen significance level ($\alpha$). If the p-value is less than or equal to $\alpha$, you reject the null hypothesis; otherwise, you fail to reject it.
Therefore, the correct sequence is (b), (d), (a), (c), (e).
