Linear algebra

concrete, not all of them are valuable since they are in accordance with many trial and errors. As mentioned earlier, three different models of multiple linear regressing (MLR), artificial neural network (ANN), and ANFIS are used to reach the goal in this study. These models are defined comprehensively in the following sections. 3.1. Multiple Linear Regression Model (MLR) Generally, regression models can be considered as the process of fitting models to data. In order to handle the…

The survey instrument created for this study includes relational questions to discover whether one or more working conditions predicts teacher retention and whether the absence of one or more working conditions predicts the likelihood a teacher will leave teaching or migrate to a new building. The survey contains both Likert-type scaled response ratings and demographic questions designed to identify teacher characteristics such as grade level. There are four constructs in this study: academics…

In his article entitled “Is Google Making Us Stupid?” (2008), Nicholas Carr, a published technology author, argues that the use of the internet has altered the way our mind thinks, the way we communicate, and even the way we read. This affects society in such a way that we are no longer able to focus while reading printed text, let alone online articles with distracting factors such as hyperlinks and flashy pop up ads. Carr provides several sources of anecdotal evidence, case studies, and…

All the scenes in the play were short and barely any characters were called by name. They also did not go in order of the pamphlet that spells “Shakespeare.” Throughout my paper, I try to describe each scene to the best of my ability with the info of which play they are acting out or about just the scenes in general. The beginning of the play began with people cleaning up the stage with brooms. The three people were slouched over sweeping close together. This showed medium topography and close…

First, the variable Percentage Black Students had a medium negative correlation (r = -0.59) to QDI. A linear regression analysis using Black Student Percentage as the independent variable and QDI the dependent variable resulted in a linear regression equation with a y-intercept of 163.11 and a slope of -0.27, which is statistically significant due to a p value of 0.01. The results of the regression analysis for these variables…

In the article “The Happiness of Pursuit” by Jeffrey Kluger, multiple tables are provided showing different data and percentages on certain factors of happiness. Looking at the tables on the page title “Got Joy,” there was three in specific that caught my eye. The first being the one labeled “Then and Now” which shows the difference in percentages from 2004 to 2013 in whether people described themselves as optimists or pessimists. The percent of Optimist decreased from 70% to 50%, which can…

Stress is a very complex topic. To my understanding it is an emotion felt not only mentally but physically as well. A large straining that you endure from being under immense pressure, at times you feel there is no way out. It can come from the negativity of your peers, and almost always from your very own self-doubt. Stress to me as a student and as a worker are very separate functions. From my student side I worry about not doing well on not only one but a series of demanding tasks from all of…

2.5. Statistical analysis Multivariate analysis was performed using two algorithms: PCA and 2-D HCA heat map. The PCA, based on the correlation matrix, was performed using XLStat-Pro 2015 software. The 2-D HCA heat map was carried out with the ArrayTrack, and the Ward's minimum-variance method was used for runs and hydrocarbons clustering. A probability level of p=0.05 was considered as significant difference. The data obtained from the RSM on the hydrocarbon removal were subjected to the…

Reliability Table 4.5 Reliability Test Variable Cronbach’s Alpha N of Items Remark Brand Awareness 0.825 5 Reliable Brand Association 0.757 3 Reliable Perceived Quality 0.763 4 Reliable Brand Loyalty 0.890 5 Reliable After validity test, this is the result of the reliability test. The requirement to be reliable is the Cronbach’s Alpha must be more than 0.7. As seen from the table 4.5 the Cronbach’s Alpha of every variables are more than 0.7 which are remarked as reliable. To be explained, the…

Data analysis method First, using Kolmogorov-Smirnov Test to examine the normality of the variables in each 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…
