Platform preference in the probe trial was analyzed using a one-sample t-test, with chance set as the hypothetical mean (25%).
Sources close to the manager still insist that his recent statements about a possible move to the Premier League were only hypothetical, meant in relation to a distant, future life after Dortmund.
For statistical analysis a two tailed one sample T-test (comparing the mean fold change with a hypothetical mean of 1) was used.
This was further confirmed by one sample t-test assuming a hypothetical mean of 25% time spent in each of the 4 quadrants showing that only Atxn2 ko mice spent more time in quadrant 1 on day 10 (one sample t-test, P = 0.025 for Atxn2 ko, and P = 0.21 for wt mice).
We thus performed a 1-sample t -test between rating scores obtained for the "vestibular activation" condition as compared with a hypothetical mean of 3 (of 5).
The limit of resolution of V1/2, the parameter with the largest error, was estimated with a z-test which formally tests for the difference between the mean of a population and a hypothetical mean.
The open trial [ 38] provided promising support for our hypothesis: omega-3 fatty acid supplementation significantly attenuated PTSD symptoms at 3 months as a primary outcome, as compared with the hypothetical mean.
Pairwise comparisons were done with Student's t test or Mann-Whitney U. When comparing to a hypothetical mean, one-sampled t tests with Sidak's post hoc test correction were used.
The 'mixed effects model' approach used in this study allowed us to generate developmental stage 'estimates' from two-channel arrays, which can be expressed as mean fold-change values (biological replicates = 6) of transcript abundance at one stage relative to a hypothetical mean value of zero across the entire experiment.
Effect sizes for the two treatment satisfaction scales (DTSQsDiff and DTSQc) were compared separately for the At Ceiling and Not at Ceiling groups, by testing the mean rated change (DTSQc) or DTSQsDiff scores, by t-tests against a hypothetical mean of zero and converting the resulting t-values to values of r, as a measure of effect-size.
