Using the bootstrap method, valid bootstrap confidence intervals can be constructed for all common estimators such as the sample mean, median, proportion, difference in means, and difference in proportions.
Topics covered include: descriptive statistics, graphical displays of data, introduction to probability, expectations and variance of random variables, confidence intervals and tests for means, differences of means, proportions, differences of proportions, chi-square tests for categorical variables, regression and multiple regression, an introduction to analysis of variance.
For means, proportions, differences in means, or differences in proportions, the precision is generally reported as an approximate 95% confidence interval calculated as the estimate ± two times the standard error of the estimate.
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.
Diagonal elements: mean proportion of within-clade pairwise differences.
Post hoc tests with Tukey correction were performed to detect any pairwise differences among mean proportion prey missing between species.
Despite important differences in mean proportion of IBD sharing between Quebec and HapMap CEU, we noted the presence of a common peak of IBD on chromosome 6 covering the HLA region.
To determine differences in mean proportion of spores with only one cell present between strains, two sample binomial tests were used to compare the WT with each individual strain, Δ ZtCBR1- 1 and Δ ZtCBR1- 2. Statistical analyses were carried out using the GenStat (2014, 17th edition, © VSN international Ltd ,Hemel Hempstead, UK) statistics package.
No statistical difference in the mean proportion of MyoD+ SCs or myogenin+ SCs was found between the groups.
We found no age-related difference in the mean proportion of astrocytic coverage (One-way ANOVA between groups, F 3,71) = 1.18, p = 0.32, Fig. 1i).
