D) ​confounding bias

Quizplus · Accepted Answer

This is commonly referred to as data dredging, where multiple comparisons are made without any specific hypothesis in mind, increasing the likelihood of finding false positive associations. This practice is often discouraged as it can lead to erroneous conclusions. Selection bias refers to the bias introduced in the selection of study subjects, measurement error is referred to as measurement testing, and confounding bias occurs when the effect of an exposure on an outcome is mixed with the effect of another factor.
