Meanings in context

Article-grounded definition

the outcome’s population standard deviation.

\bar{Y}_n - \bar{Y}_N = \rho_{R,Y}\sqrt{\frac{1-f}{f}}\,\sigma_Y ,

This equation states an equality: the expressions on both sides have the same value under the article’s assumptions.

\sigma_Y

the outcome’s population standard deviation.

\sigma_Y \le 0.5

This equation states a bound: one expression must stay on the indicated side of the other under the article’s assumptions.

\mathrm{CSDB}_c(\delta) = \frac{\delta}{\sigma_Y}\sqrt{\frac{f_c}{1-f_c}} .

This equation states an equality: the expressions on both sides have the same value under the article’s assumptions.

\sigma_Y = 0.3

This equation states an equality: the expressions on both sides have the same value under the article’s assumptions.
