Probably Error of the Mean and the t-test Table which consider the differences between two groups by looking at their means while weighing their sample error that is influenced by sample size. Slide 8: Another term that you will report about your statistical results or findings is the ‘degrees of freedom.’ This term refers to how many values are free to vary in a set of values if we know the summary statistic and the number of values in the set; how many values would we need to know in order…

In this experiment, the two sets of data obtained from the same subjects were analyzed. First, the JNDs from the four subjects was pooled together and a repeated measures ANOVA analysis was performed. Then, Weber’s fractoin (JND/line length) was applied to the original data to compute the weber fraction and the same analysis test were performed. For this study, we were specifically interested on the data yielded from the Test of Within-Subjects Contrast and Effects and an ANOVA performed from…

(3) Equation (3) gives limit moment about 11% higher than equation (2) regardless of h. One notable point is that the above solutions depend only on bend factor(h), not on r/t and R/r. Equations (1-3) are applicable only for the pure in-plane bending moment and the effect of internal pressure is not taken in to account. Also these analytical solutions consider constant wall thickness along the contour of the pipe bend cross section. However, the most of the pipe bends are made using a forming…

2-8- Statistical analysis Results are presented as mean±standard deviation (SD) of two replicated determinations. Data were subjected to one-way analysis of variance (ANOVA) and multiple comparisons were performed by Duncan's test. Statistical significance was set at P>0.05. All analyses were performed using SAS version 9.1 (PROC GLIMMIX; SAS Institute Inc., Cary, NC). 3. Results and discussion 3-1- physicochemical changes of grape juice contain encapsulated probiotics 3-1-1- pH According to…

If 5 cuvettes containing spinach/DPIP solution are covered with different cups so that they absorb light of different wavelengths, then the cuvette with no filter will transmit the most orange light because it has been exposed to all white light and has the fastest rate of photosynthesis, followed by cuvettes under red cups, blue cups, green cups, and finally under the opaque cup because it has been exposed to no white light and has the slowest rate of photosynthesis. Fig. 1 and Fig. 2, which…

questions assignment. The question is the following: Are individuals with dual diagnoses, such as developmental disability and mental disorder less likely to receive appropriate mental health assistance than individuals with a mental disorder only? The statistical analysis that would be used for this research question is factorial ANOVA. According to Sukal (2013), “factorial ANOVA is one that includes multiple independent variables and one dependent variable” (Sukal, 2013, para. 1). For this…

The hypothesis based on the findings of Latane and Darley (1968) that as the number of participants increased, help would become less likely was somewhat supported. The results in the graph Percentage of people who helped/did not help highlighted that the bystander effect occurred as the smallest group size had the highest help rate of 100%, and the percentage of participants who helped in the group of 19 was higher than that of the group of 35, 10.5% and 2.90% respectively. However, the groups…

More than 65% of ovules were just enlarged without undergoing callus or shoot phase independent of the sucrose concentration. Rest of the ovules was either with no development or dead after 8 weeks of culture period. The effect of sucrose concentration on ovule response was not pronounced (Table 18). When comparing the suitability of sucrose concentrations (2% or 4%, 4% 0r 6%, 2% or 6%) for ovule culture depending on the genotype, there is no significant difference for both genotypes on whatever…

I. INTRODUCTION The performance of present computing systems has increased at the cost of considerably enlarged power consumption. The increased power consumption either reduces the operation time for battery powered systems, such as hand-held mobile systems, or generates extreme amount of heat and requires expensive sophisticated packaging and cooling technologies, especially for complex systems that consist of several processing units. The generated heat, if not efficiently removed, can also…
