Sentence examples for mean difference has from inspiring English sources

The mean difference has variance: and can be estimated using maximum likelihood estimation from observed differences while taking into account correlations among environmental factors.

This estimate of the effect size using standardised mean difference has a slight bias overestimating the effect size, and we applied a correction factor to convert the effect size to Hedges' g. 32 We used meta-analysis to combine the individual study results by using the Stata software package (version 13.0).

For these studies the standard deviation was either estimated from graphs or expropriated from the data of other sources; details of which are provided in the legends of figures 2, 3, 4. The pooled weighted mean difference has therefore been calculated after excluding these studies to indicate the effect these studies may have had upon final results.

As three repeated volume measurements of pulmonary nodules were performed by the same reader and the same software for each reconstruction setting, the mean difference between replicates is expected to be zero, implying that the backward transformed mean difference has a ratio of 100%.

However, the choice of effect (e.g., log odds ratio, sample mean, standardized mean difference) has a substantial impact on the distribution of Q for small to moderate sample sizes, which in turn affects the use of Q as a statistic for a test of homogeneity.

31 The pooled standardised mean difference had a medium effect size but was non-significant (0.51 (95% confidence interval −0.18 to 1.20); fig 5).

Additionally, means within the complaint groups and mean differences have been computed for continuous variables such as depression and anxiety.

To determine test-retest reliability, ICC values, mean difference and 95% CL of the mean differences have been reported as appropriate and clear, though several authors use other measures (such as Pearson's correlation coefficient, coefficient of repeatability and coefficient of variation) [ 22].

Independent sample t-test of mean and proportion difference has been carried out for observing if there is any significant difference between control and treatment groups.

If the correct dose had been selected, the mean difference would have been zero.

The difference has never meant much to most consumers, who directly pay only for energy, as measured in kilowatt-hours.
