this article aims to provide a simple robust method to test the parameters of a normal population by using the new diagnostic tool called the “forward search” (fs) method. the most commonly used procedures to test the mean and variance of a normal distribution are student’s t test and chi-square test, respectively. these tests suffer from the presence of outliers. we introduce the fs version of...

Performance-based outcomes such as the T-Test, Edgren Side Step Test (ESST), and Illinois Agility Test (IAT) have been used to assess agility in athletes and nonathletes; however, the reliability and validity of these tests have not been established. The purpose of this study was to establish the reliability and convergent construct validity of the ESST, T-Test, and IAT in young, nondisabled, p...

BACKGROUND Methamphetamine is a neurotoxic agent. Its chronic abuse may result in cognitive impairment with negative consequences for patients' treatment and rehabilitation. The aim of the study was to compare Wisconsin Card Sorting Test profiles of Czech subjects dependent on methamphetamine with healthy individuals.

The H-T-P (freehand drawing of House, Tree, and Person) is a technique designed to aid the clinician in obtaining information concerning the sensitivity, maturity, and integration of a subject's personality, and the interaction of that personality with its environment (both specific and general). The H-T-P is a two-phased approach to the personality. The first phase is non-verbal, creative, alm...

Testing linear combinations of normal group means with unequal variances and possibly unequal samples sizes using a t-statistic is a well known problem for which the effective degrees of freedom are unknown. ? and ? set forth their approximations based on the ratio of combinations of fourth moments, and their methodology remains the de facto standard. We propose a new approach that extends thei...

Statistical tests are very important in biomedical research.1 Several factors play a role in selecting the most appropriate statistical test.2 The misuse or inaccurate use of a statistical test may navigate the research in the wrong direction, and hence incorrect conclusions. Because it is probably the most commonly used statistical test, Student’s t-test is considered “the bread and butter” of...
