Statistical tests are powerful tools for data analysis. Kruskal-Wallis test is a non-parametric statistical test that evaluates whether two or more samples are drawn from the same distribution. It is commonly used in various areas. But sometimes, the use of the method is impeded by privacy issues raised in fields such as biomedical research and clinical data analysis because of the confidential...

An analysis is made of the perception of musical intervals. Two kinds of stimuli were used; intervals consisting of two simultaneous simple tones (sinusoids) and intervals consisting of two simultaneous complex tones (fundamental plus harmonics). Subjects judged the stimuli by the method of triadic comparisons in an incomplete balanced design. Multidimensional analysis was performed according t...

OBJECTIVES This study was aimed to describe lecturers' perspective concerning the suitable Conscientiousness Index (CI) components and implementations, as well as to compare the CI scores in year 1-4 student batches. METHODS Components were formulated from objective measurements based on interviews with 12 faculty members. The components include: attendance, adherence to rules, evaluative fee...

with error bars of 2 SD, the results may be seen in perspective (fig. 1, lower panel). The investigators described repeat testing for differences between the groups by Student's unpaired t test or by Mann— Whitney U test, and stated that they then confirmed the differences by analysis of variance or by Kruskal-Wallis. However, it is invalid to test repeatedly by Student's or by Mann-Whitney unl...

PURPOSE To analyse prognostic features on quality of life (QoL) following radical cystectomy and urinary diversion via orthotopic neobladder in a single-centre patient cohort. MATERIALS AND METHODS Postoperative QoL of 152 patients was assessed retrospectively using the validated QLQ-C30 questionnaire. Potential associations of patient's quality of life including pre-and intraoperative charac...

A descriptive analysis was made in terms of the related radiation induced acute and late mucositis and xerostomia along with survival and tumor control rates (significance level at 0.016, bonferroni correction), for irradiation in head and neck carcinomas with either 2D Radiation Therapy (2DRT) and 3D conformal (3DCRT) or Intensity Modulated Radiation Therapy (IMRT). The mean score of grade > I...

introduction: the antimicrobial efficacy of root canal irrigant plays an important role in increasing the success of root canal treatment (rct). the aim of the present experimental study was to compare the antimicrobial activity of triphala (a plant-derived solution) with 0.5, 1, 2.5 and 5% concentrations of sodium hypochlorite (naocl), against enterococcus faecalis ( e. faecalis ). methods and...

Three protein peaks were identified in the serum of men with prostate cancer and BPH, but not in controls, with relative molecular masses of 15.2, 15.9 and 17.5 kDa. These three proteins were significantly associated with BPH and prostate cancer when compared with controls ( P = 0.001, 0.004, and 0.011, respectively, Kruskal–Wallis test). Interestingly, the 17.5 kDa protein was more abundant in...
