χ Tests were used for testing differences between four different types of clinics.
This generated 17 subtly different ROIs, which provided statistically independent regions for testing differences between the 4 models described earlier.
We experimentally manipulated the opportunity for mating in replicate populations of Drosophila melanogaster by removing components of sexual selection, with the aim of testing differences in short term post-mating effects of females evolved under different mating strategies.
In agricultural studies, estimating and testing differences between treatment regimes in a designed experiment usually determines the subsequent success or failure of inputs or management practices.
To quantify differences beyond subjects of conversation, we tested other statistics using the same method we used for testing differences in word usage: frequency of letter usage, letter pair usage, word length and three-letter word ending.
Although both mean and median were significantly different from 0 for this group of stenosis, p-values were not as small as those from testing differences between CDUS and CTA (diameter).
For this, we used the multiresponse permutation procedure (MRPP), a non-parametric method designed for testing differences among a priori defined groups [38].
Whole brain cortical thinning between ALS patients and healthy participants was assessed using General Linear Model (GLM) by testing differences at all vertices.
It is a method that is probably more useful for testing differences in the mean and variances of groups along specific, constrained axes of morphospace.
The procedure, explained in detail below, was identical for testing differences between waveforms in both experiments and scalp topographies in Experiment 2. The statistical analysis of SSR waveforms was performed across the temporal dimension for each stimulation condition separately.
When testing differences of parameters we also used a t-test and estimated the standard error of the difference using the delta method (if coming from two different samples assumed that samples were independent).
