What Would Result from an Ideal Experiment

Question

What would result from an ideal experiment?
A) high sampling error
B) small treatment effect
C) low standard error
D) large confidence interval

Accepted Answer

An ideal experiment would have low standard error, indicating that the mean values of the sample are consistent and close to the true value. High sampling error, small treatment effect, and large confidence interval would indicate that the experiment is not ideal and there is more variability or uncertainty in the results.
