Why is it necessary to adjust the individual confidence level of each confidence interval for a multiple comparison of means procedure?


▸

The total probability of the \(\style{font-family:Times New Roman;}{\left(\begin{array}{c}k\\2\end{array}\right)}\) intervals being correct will always be less than the probability of any single confidence interval covering a single mean difference.



▸

Each confidence interval is slightly biased and the correction will alleviate that bias.



▸

The \(\style{font-family:Times New Roman;}{\left(\begin{array}{c}k\\2\end{array}\right)}\) intervals will not be able to detect slight differences in means without a correction.



▸

Confidence intervals are always estimates; so, when considering \(\style{font-family:Times New Roman;}{\left(\begin{array}{c}k\\2\end{array}\right)}\) of them, an adjustment is needed to allow for valid inference.
