* SEM: Standard error of the mean
based on Mean Square Error of ANOVA analysis.
Data represents the mean [+ or -] standard error of the mean
Mean [+ or -] standard error of the mean
(SEM; n = 3-4) values are provided.
Data are shown as the mean [+ or -] standard error of the mean
. *** P < 0.001 versus saline group, ### P < 0.001 versus MPTP group, and ([dagger[dagger]) P < 0.01 versus HT7 group.
The mean of the interspinous distance was 23.2 cm (CI 95 % 23 to 23.4), with a standard error of the mean
of 0.1, a variance of 1.7 and standard deviation of 1.3.
High incorrect use of standard error of the mean
(SEM) in original articles in three cardiovascular journals evaluated for 2012.
The Standard Error of the Mean
of Maximal Cardiorespiratory Testing (n = 10).
The means with different letters in each column are significantly different according to Duncan's Multiple Range Test (less than 0.05 p value) +- Standard error of the mean
If minimization is perfect, there is no difference between the group means of the subject characteristic, so the typical difference of a group mean from the population mean is given by the standard error of the mean
of a sample of size 2n with two groups, 3n with three groups, and so on.
All of these indices have potential uses (eg, standardised effects can be used for meta-analysis, and the standard error of the mean
and the minimum detectable change are useful clinimetric indices).
The sample mean = $923.62, the hypothesis gave us population mean = $1100; and the standard error of the mean
= (standard deviation/square root of sample size) = 84.64/10 = 8.464.
Specifically, there is a statistical concept called the "standard error of the mean
" which directly measures variability.
