What are some examples of sequential testing?

Sequential testing is a statistical method where data is evaluated as it is collected. For example, in clinical trials, researchers might analyze data after each participant to decide whether to continue or stop the trial.

Can you give me a specific example in a clinical trial?

Sure! In a clinical trial for a new drug, researchers might use sequential testing to monitor the effects on patients. If a significant number of patients show improvement after a certain number of doses, they may decide to continue the trial. If not, they might halt it early.

What are the benefits of using sequential testing?

The benefits include faster decision-making, reduced costs, and the ability to stop trials early if results are unfavorable, which can protect participants from ineffective treatments.

Are there any drawbacks to this method?

Yes, drawbacks include the potential for increased Type I error rates and the need for careful planning to ensure that the testing remains statistically valid.
