Robust and Nonparametric Methods for Topology Error Identification and Voltage Calibration in Power Systems Engineering
… well as identify gross measurement errors. The Friedman Two-Way Analysis of Variance by Ranks test is advocated to calibrate voltage measurements at a bus in a power network. However, it was found that the Friedman test was only slightly more robust or resistant in the presence of discordant …

Impact of Interruption Frequency on Nurses' Performance, Satisfaction, and Cognition During Patient-Controlled Analgesia Use in the Simulated Setting
… measures were completed for each of the four test conditions. The research questions were answered using repeated measures analysis of variance with (RM-ANOVA), McNamar*s test, and Friedman*s test. After each experiment, semi-structured interviews were used to collect data that were analyzed …

Determining the functionality of traditional leadership councils as agents of rural development in Vhembe District, South Africa
… District, for example, land disputes, violent protests and xenophobic attacks are experienced. This situation raises the question whether TCs are really functional. Multi stage stratified random sampling was used to select six out of the 43 TCs in the Vhembe District for the purpose of the current …

Vegetative and reproductive biomass allocation responses of herbaceous plant species to induced drought in a semi–arid highland savanna, central, Namibia
… allocation (χ²(1) = 17.103, p < 0.004). The Friedman test results show a significant difference in chlorophyll content across drought treatments (χ² = 18.456, df = 1, p < 0.001), with Aptosimum lineare and Ocimum americanum exhibiting the highest chlorophyll levels under treatment 60 …

Evaluation of methods for determining bulk specific gravity of Hma specimens
… unrutted specimens. The bulk specific gravity test results were compared for similarity of the methods and repeatability of the measurements for each method. Analysis of the data showed that (1) for unrutted specimens, the bulk specific gravity measurements by Water Displacement(TM) method are …

Age-related proliferative behavior of mandibular osteoblasts : an in vitro study
… was measured using two different proliferation tests (MTT and EZ4U). These depend on the mitochondrial functional activity of the cells and not only on their staining. The difference in cell number and size between the three age-groups was also determined and statistically analyzed using the …

The Reliability And Validity Of The Thin Slice Technique: Observational Research On Video Recorded Medical Interactions
… validity of thin slices was assessed using the Friedman test (non-parametric equivalent of the Repeated measures ANOVA), and the comparison of thin slice coding to full interaction coding was assessed using the Wilcoxon Sign Ranks test (nonparametric version of the Paired t-test). </p> <p> …
