  • Using Kolmogorov-Smirnov Test To Examine The Normality Of

    the hypotheses and assumptions of one to five using regression analysis and using software Spss18 and then fourth hypothesis using structural equation modeling (Path Analysis) using software Amos22 to confirm or refute the hypothesis of the research study. Hypotheses: 1. Empowerment dimension effect on turnover intention. 2. Interoperability dimensions have an effect on turnover intention. 3. Empowering (General) effect on turnover intention. 4. Interoperability (total) effect on turnover intention. 5. Empowering effect on interoperability. 6.Empowering through interoperability has an effect on turnover intention. Results Since the normal distribution of variables in the regression, is the most important default, before examining hypotheses, using non-parametric test Kolmogorov - Smirnov, was investigated assuming normal distribution of data related to each of the variables. In all tests performed in this study,…

  • Time Aggregation Effect Of Vvr In Financial Market

    Based on equation 1.1, 1.2 and the methodology proposed by Baumol, with a certain confidence level c, we can work out the VaR by, rVaR=-W_0 (R^*-μ) Equation 1.3 Rearrange equation 1.3 from the standardized variable we can get rVaR=W_0 ασ Equation 1.3.1 I-2 Research Question The general idea of VaR model can be shown by equation 1.3.1. However, there is an assumption for financial institutions to process which is known as time aggregation associate with σ in…

  • Life After 9/11 Investigation

    We must assume either that each student is independent of each other or that any dependence is minimal in perspective. The population of high school seniors in upstate New York is presumable ten times greater then the sample size of 500 people. We are told in the problem statement that the students were selected at random. Students answers mattered only as a success or failure in whether they planned to attend college or not. In addition, n p̂ >10 at 26 people and n q̂ >10 at 474…

  • Non Preferred Hand Pattern Essay

    Discussion: The distribution of each graph is quite comparable as they have similar means and standard deviation, where the preferred hand has a mean of 16.33 and a standard deviation of 2.842 whilst the non-preferred hand has a mean of 17.2 and standard deviation of 2.848. The normal distribution graph of each can be seen below: Preferred Hand vs. Non-preferred Hand: The graphs and boxplots (Figures 1.3- 1.6) seen previously in the results indicate that the two results did not have a normal…

    parametric and nonparametric analyses of variance referred to as ANOVA by sum of squares or ANOVA by rank, respectively (Figure 2). Pearson product moment correlation coefficient It can be used to measure the intensity of association between variables. The data must be normally distributed. It defines both the strength and direction of the linear relationship between two variables. It does not imply causation. Regression analysis Regression quantifies the numerical relationship between 2…

  • Cowles And Davis 2006

    Question 1 Cowles and Davis (2016) discussed several factors that contributed to the adoption of the .05 level of statistical significance. The first factor discussed was the discovery that computations can be utilized to measure observational error, by and astronomer, Lambert Adolphe Quetelet. This discovery led to the development of the normal distribution curve utilized today (Cowles & Davis, 2016). Following the development of the normal distribution curve, a measure of variability known…
