Sentence examples for deviation mean difference between from inspiring English sources
A power analysis using data from a previously published thesis [17] indicated that with a sample of at least 30 subjects in each group, the study has a power of at least 80%, (type error of 5%) to detect 1 standard deviation mean difference between the groups.
Numerical variables were summarised as means, standard deviations, mean differences and proportions of change between baseline and follow-up after 16 weeks.
The mean differences between the two methods and the mean differences ±2 standard deviations of the difference between the methods were applied.
It is calculated as 1.96 multiplied by the standard deviation of the mean differences between the two sets of data.
SEM was calculated as the standard deviation (SD) of the mean differences between test and retest divided by √2.
The standard error of measurement (SEM) was calculated, as suggested by de Vet et al, 2006, using the formula: SEM = Standard deviation of the mean differences between tester A and B divided by √2 [ 42].
Furthermore, measurement errors were estimated by calculating the Standard Error of Measurement (SEM) using formula: SEM consistency = SDdifference/√2 (SDdifference = Standard deviation of the mean differences between examiners A and B).

Effect sizes are calculated as follows: [mean(a) – mean (b)/largest standard deviation score (SD ], this means that differences between groups are expressed in units of the largest within-group standard deviation.
The balancing factor reflects the importance of the maximal deviation of the indicators, where the maximal deviation means the maximum difference between an indicated value and the best value for the indicator (Dahab and Lee [1991]).
