Materials and methods This cross-sectional study consisted of 34 women from the city of Londrina, with age range from 44 to 55 yrs., were divided into two groups: I.DM (patients with Type 2 Diabetes, n=7) and II.Control (normal subjects, n=27). The diagnosis of diabetes was made through a clinical and laboratory evaluation. To assess the level of physical activity was applied the International ...

Hepatitis A virus is an important widespread virus that usually causes more severe medical consequences in patients with chronic liver disease. The purpose of this study was to evaluate prevalence of Hepatitis A Virus antibody in patients with chronic HCV in Isfahan province, Iran. METHODS A cr...

Purpose: To examine the clinical implications of prostatic calculi in terms of links to chronic pelvic pain, voiding and sexual functions. Methods: 60 adult males were recruited for this study. The parameters recorded were: age, weight, height, Body Mass Index (BMI) calculated as the weight in kilograms divided by the square of the height in meters, Waist Circumference (WC), Lower Urinary Tract...

The growing volume of data usually creates an interesting challenge for the need of data analysis tools that discover regularities in these data. Data mining has emerged as disciplines that contribute tools for data analysis, discovery of hidden knowledge, and autonomous decision making in many application domains. The purpose of this study is to compare the performance of two data mining techn...

The Chi-square statistic is a non-parametric (distribution free) tool designed to analyze group differences when the dependent variable is measured at a nominal level. Like all non-parametric statistics, the Chi-square is robust with respect to the distribution of the data. Specifically, it does not require equality of variances among the study groups or homoscedasticity in the data. It permits...

In the present study, a model was developed to describe relationships between impacts of intra-group conflict on group performance-moderating role of cultural diversity. Data from 170 employees working in teams of GSM cellular companies located in Pakistan support our hypothesis. Data was analyzed through SPSS. Findings indicated that intragroup conflict had direct negative effects on group per...

The original chi-square test, often known as Pearson’s chi-square, dates from papers by Karl Pearson in the earlier 1900s. The test serves both as a ”goodnessof-fit” test, where the data are categorized along one dimension, and as a test for the more common ”contingency table”, in which categorization is across two or more dimensions. Voinov and Nikulin, this volume, discuss the controversy ove...

Scientists often use the Chi-square (χ) test to determine the “goodness of fit” between theoretical and experimental data. In this test, we compare observed values with theoretical or expected values. Observed values are those that the researcher obtains empirically through direct observation. The theoretical or expected values are developed on the basis of an established theory or a working hy...
