Question

Quizplus · Accepted Answer

A perfect experiment aims to maximize treatment variance, which is the variance due to the independent variable or treatment effect, and minimize error variance, which is the variance due to uncontrolled variables or noise. This ensures that the results are more likely to be due to the treatment rather than random or uncontrolled factors.
