2.4. Data Analysis For the analysis of the quantitative data, one-way ANOVA, Chi-Square test of independence and descriptive statistics were applied. For ANOVA, in order to determine which groups caused the significant difference, Tamhane T2 test, one of the most common post hoc (multiple comparison) tests, was used. For the normal distribution of data, the skewness and kurtosis coefficients were examined. For the normality test skewness coefficient of a distribution taken in the range of -1.5…

Explain TABLE REGRESSION Table 4.9: Result of simple linear regression between level and ovitrap index Variable SLR Level b (95% CI) p-value -2.5 (-7.7, 2.9) 0.236 R2 = 0.421. The model not fit well: Model assumption are not met There is statistically no significant linear relationship between level and ovitrap index (p= 0.236). The increase of the multi –storey house level is not associated with the ovitrap index level. With level, the model explains 42% of variation of the ovitrap…

Table 4.2 System suitability results for Lamivudine, Zidovudine and Nevirapine Parameters Lamivudine Zidovudine Nevirapine Retention time 2.327 2.864 5.608 Area 212473 338930 228426 USP Plate count 2715.09 3350.07 4979.51 USP Tailing 1.38 1.32 1.18 4.3.1.2 Linearity A linear correlation coefficient factor was obtained between the concentrations of Lamivudine, Zidovudine and Nevirapine versus the peak area. The calibration curves were linear for concentrations between 15-150 µg/mL. The linearity…

Assignment 7 1. The correlations between the performance in the Shot Put event and the nine other events of the decathlon ranged from r(107) = .042 to .789. The two strongest correlates of the performance in the Shot Put event were the performance in the Discus Throw event, r(107) = .79, p <.001, and the 100m Dash event, r(107) = .50, p < .001. The effect size of the correlations between the performance score in the Shot Put and these two decathlon events are large, which suggests that…

I. Introduction A special program was designed to improve knowledge, attitudes, and practice (KAP) regarding nutrition. The control group was comprised of a sample of 10 males who received the standard nutrition education program. The experimental group consisted of a sample of 10 males who received the KAP nutrition education program. For each program, the participants received 45 minutes of instruction twice a week for 15 weeks. All participants completed a pre-test and post-test to assess…

• Macro and Micromorphology Analysis Colony diameters after 7 days at 25°C were as follows: CYA: 70-77 mm, MEA: 56-60 mm, YESA: 69-79 mm, OAT: 42-45 mm, CREA: 3-4 mm and CYA + 5% NaCl: no growth. On CYA at 10ºC conidia germinate, at 15ºC, 20ºC and 30ºC growth is evident with colony diameters of 9-17 mm, 59-71 mm and 56-86 mm, respectively. The species does not grow on CYA at 37ºC and 42ºC while at 33ºC the colony diameters varies from 0 to 22 mm, indicating that at this temperature the growth…

Chapter 5 RESULTS AND DISCUSSION 5.1 Compression Test The compression test results for Granite epoxy specimens is documented and listed in Table 5.1. Table 5.1 Compression Test results for Granite Epoxy Specimens Figure 5.1 shows the compressive strength plot of granite epoxy composite specimens without the inclusion of filler material. From the graph, it is observed that the compressive strength of the fabricated specimen’s increases up to 70% granite content and further decreases with the…

A0130036Y Method 1: Box Plot The question asks if Road Handling is part and parcel of Practicality, i.e. whether road handling is an essential component influencing/affecting another data group, practicality. Thus, road handling is taken to be the independent variable, x, and is ranked from the lowest to the highest score. The data is split into 5 groups, Group 1 and 5 containing the lowest-ranked and highest-ranked road handling scores, respectively. Group 1 2 3 4 5 Median 4.58 4.585 4.455…

5.4 Relationship between ages, races and education level of respondents with the awareness on heavy metal contamination in water convolvulus By using chi-square test, age of respondents is significantly associated with awareness on heavy metal contamination in water convolvulus (p=0.045). Based on Figure X, it can be concluded as the respondents in the age of between 18 and 54 years old are more aware on heavy metal contamination in water convolvulus compared to the age group between 55 until…

The education system today has the whole pedagogical process down to a science. Take a certain percentage of the student’s multiple choice score and then multiply the free response score by a seemingly random string of digits, then consider the weighted average, so and so forth. Then after crunching the numbers out comes the perfect student: One who can write the proper essay, the correct lab report, correctly perform an experiment, correctly, proper, right. But the system rarely stops to…
