Standard deviation of the differences, sd, sdiff, английский
A statistic calculated as part of paired t-test analysis. it is the standard deviation of the individual differences between pairs of values (xi, yi), after those differences have been corrected for any systematic error or bias between the methods. when applied to data from a comparison of methods experiment, its properties are similar to those of the standard deviation about the regression line, except that the presence of proportional error contributes to sdiff and invalidates its quantitative interpretation.
