What is bias in sequential testing?

What is bias in sequential testing?

Bias in sequential testing refers to systematic errors that can affect the results of tests conducted in stages, leading to misleading conclusions.

Can you give an example of how bias might occur in this context?

Sure! For instance, if a test is conducted in multiple phases and the criteria for stopping the test are influenced by early results, it may introduce bias.

How can we minimize bias in sequential testing?

To minimize bias, it's important to predefine stopping rules and ensure that all phases of testing are conducted under consistent conditions.

Are there specific statistical methods to address this bias?

Yes, methods like Bayesian approaches or adjusting for multiple comparisons can help mitigate bias in sequential testing.
