# Conducting Hypothesis Tests

Now you know what a Hypothesis Test is, this page has some examples of conducting hypothesis tests. There are generally two approaches to conducting hypothesis tests. One approach is to calculate the probability of the experiment and compare this with the significance level. The other is to calculate the critical region and see where the test statistic falls. Here is a list of steps that you should follow in each case when conducting a hypothesis test:

## Approach 1:

- State your null and alternate hypotheses including an introduction to the test statistic.
**Conduct the experiment.****Identify the distribution of the test statistic and calculate the probability of at least the outcome of the experiment happening by chance if the null hypothesis were true. Note that thisย**usually**ย requires the calculation of multiple probabilities.****Compare this probability with the chosen significance level.**- Make your conclusion – should you reject or accept the null hypothesis? Interpret the conclusion in terms of the original context.

## Approach 2:

- State your null and alternate hypotheses including an introduction to the test statistic.
**Choose your significance level.****Identify the distribution of the test statistic and calculate the critical region as determined by the chosen significance level.****Conduct the experiment and see if the outcome falls in the critical region.**- Make your conclusion – should you reject or accept the null hypothesis?ย Interpret the conclusion in terms of the original context.
