What are some case studies of sequential testing?

What are some case studies of sequential testing?

Sequential testing is a statistical method used to evaluate hypotheses as data is collected. One notable case study is in clinical trials, where researchers use sequential testing to determine the effectiveness of a new drug more efficiently.

Can you give me more details about that clinical trial?

Sure! In a clinical trial for a new cancer treatment, researchers used sequential testing to analyze patient responses after each phase. This allowed them to stop the trial early if the treatment was found to be significantly effective or ineffective, saving time and resources.

What are the advantages of using sequential testing?

The main advantages include reduced sample size, faster decision-making, and the ability to adapt the study based on interim results, which can lead to more ethical research practices.

Are there any drawbacks to sequential testing?

Yes, some drawbacks include the complexity of the statistical methods involved and the potential for increased Type I error rates if not properly controlled.
