The Ryan-Einot-Gabriel-Welsch test [14] was used for post hoc analysis to comparisons between the 3 patient groups, with the P value for statistical significance set at ≤.05. A chi-squared test by trend [15] was used to calculate significance of patient-reported outcomes between the 3 ...

The Chi-square test is perhaps the most frequently used (or overused) nonparamteric statistical test. The Chi-square test, named for the Greek letter χ (i.e., Chi or the Greek letter for x), is typically used to test for differences in proportions between two or more groups. The Chi...

The Chi-Square Calculator makes it easy to find the cumulative probability associated with a specified chi-square statistic. Or you can find the chi-square statistic associated with a specified cumulative probability. If anything is unclear, read theFrequently-Asked Questionsor theSample Problems. To...
Subsequently Stein's method for chi-square approximation is applied to bound the distributional distance between Pearson's statistic and its limiting chi-square distribution, measured using smooth test functions. In combination with the use of symmetry arguments, Stein' method yields explicit bounds on...
SPSS 19.0 package for statistical analysis was used. Chi-square test was used to compare the differences between the various groups with a level of significance (P<0.05) (Table 1). View article Compression with or without Early Ambulation in the Prevention of Post-thrombotic Syndrome: A Systemat...
The Chi-square test for independence procedure identifies differences between two or more groups using one or more nonparametric tests. Nonparametric tests do not assume your data follow the normal distribution. With the exception of partial gamma coefficients, Chi-square test for independence statistics...
Th e Non-Central Chi-Square Chart with Double Sampling In this article, we consider a non-central chi-square chart with double sampling (DS amp;chi;2 chart) to control the process mean and variance. As in the case of Shewhart control charts, samples of fi xed size are taken from the ...
