The phrase "a standardised deviation" is not correct in English; the correct term is "standard deviation." You can use "standard deviation" in contexts related to statistics, particularly when discussing the variability or dispersion of a set of data points.
Example: "The standard deviation of the test scores indicates how much the scores vary from the average."
Alternatives: "a standardized measure of variation" or "a measure of dispersion."
In order to detect a standardised difference of 0.5 standard deviation in the primary outcome measure (which can be considered as a clinically relevant difference), 2 × 63 patients are needed when two-sided testing and 80% power is assumed.
19 We presented standardised differences as a summary measure of differences between groups; we calculated a standardised difference as the difference between the sample means (or proportions), divided by the pooled standard deviation.
In the present study, the durations of all subjects between the time points of performing the HADS and blood sampling had a mean value of 3.6 days and standardised deviation of 5.0 days, and those of 95% of all subjects were under 15 days.
The deviations from the estimated cluster means were also standardised to Finally, for all resampled clusters, the 'shrunken' mean is added to the standardised deviation for each resampled individual: This method, with the rescaling procedures will in future be referred to as the BS2 method, or double bootstrap.
This could be explained by higher mean values and bigger standardised deviation of the simulated LNG prices at Japan.

The mean, median, standardised deviation, and range of duration between the time points of performing the HADS and blood sampling of all subjects were 3.6, 2.0, 5.0, and 0 33 days, respectively.
Blinded assessors determined in a standardised fashion the deviation of the puncture off midline and whether appropriate longitudinal position between the first and fourth tracheal rings was achieved.
The difference found between the groups is equal to a standardised mean difference of −0.30 (−0.54 to −0.07), with baseline standard deviation for SCL-D13 (pooled).
Assuming a standard deviation of 4 points, (the UK BEAM sample size was based on an assumed population standard deviation of 4 points for this questionnaire) this results in a standardised effect size (difference in means/standard deviation) of 0.39.
