Null Hypothesis Testing Statistical significance is used innull hypothesistesting, where researchers attempt to support their theories by rejecting other explanations. Although the method is sometimes misunderstood, it remains the most popular method of data testing in medicine, psychology, and other fields...
Statistical analysis is routinely used in agriculture, arts and literature, biology, business and economics, education, entertainment, environment, finance, food/drink, games, health, law, media, psychology, politics, and many other fields. The process of statistical analysis is defined as studying ...

The use of the effect size in JCR Spanish journals of psychology: from theory to fact This mathematical concept illustrates that the likelihood of finding statistical significance (i.e., rejecting the null hypothesis) increases with larger sample sizes, and the likelihood of failing to find statist...
There is nothing special about the correlation analysis in Davis et al. (2008): in neuroscience and psychology these problems are very common. In the rest of this post we’re going to tackle only two of them: how to compare 2 independent Pearson’s correlations, and what sample sizes are...
Definition 1 (there are methods of constructing uniformly-distributed p-values that are not themselves tail-area probabilities), and a p-value can satisfy Definition 1 without satisfying Property 3 (when there is a composite null hypothesis and the distribution of the test statistic is not ...
Kernel discriminant analysis 96.9 3.1 0.0 0.0 Support vector machine 80.5 11.1 11.5 3.3 The comparison is rather interesting. In terms of correct classifications, the SVM approach is third behind kernel discriminant analysis and nearest neighbour. However, in terms of incorrect classifications, the SVM...
Statistical Methods in Psychology As mentioned previously, there are two different methods of statistical analysis that delineate different methods of data. They are descriptive statistics and inferential statistics that are based on the gathered data. Each type of statistic is seeking to either prove ...
