The table shown on the right can be used in a two-sample t-test to estimate the sample sizes of an experimental group and a control group that are of equal size, that is, the total number of individuals in the trial is twice that of the number given, and the desired significance level is 0.05. [4]
The effective sample size, defined by Kish in 1965, is calculated by dividing the original sample size by the design effect. [1]: 162, 259 ...
A training data set is a data set of examples used during the learning process and is used to fit the parameters (e.g., weights) of, for example, a classifier. [9] [10]For classification tasks, a supervised learning algorithm looks at the training data set to determine, or learn, the optimal combinations of variables that will generate a good predictive model. [11]
Let and be the sample size collected from each group. The permutation test is designed to determine whether the observed difference between the sample means is large enough to reject, at some significance level, the null hypothesis H 0 {\displaystyle _{0}} that the data drawn from A {\displaystyle A} is from the same distribution as the data ...
the single most important determinant of effect size was whether behavior-contingent rewards were delivered immediately or only after a time delay (Jennifer P. Lussier et al. 2006). In the case of eating, present-biased preferences typically promote unhealthy choices because the
