The Survey System uses significance levels with several statistics. In all cases, the p value tells you how likely something is to be not true. If a chi square test shows probability of .04, it means that there is a 96% (1-.04=.96) chance that the answers given by different groups...

The normal distribution is a bell-shaped curve where data clusters symmetrically around the mean, useful in statistics and natural phenomena modeling.
At a 5% significance level (95% confidence level), what is the critical value (s) in this test? Do we reject the null hypothesis? Hypothesis Testing The hypothesis test is a statistical test that is either parametric or non-parametric. In t...
For local pattern analysis tools this is because spatial dependency can artificially inflate statistical significance. Spatial dependency is exacerbated with local pattern analysis tools because each feature is evaluated within the context of its neighbors, and features that are near each...
