Skewness

Introduction The data given to us was from a small hospital in Rhode Island. The data is collected from randomly selected emergency room patients. The variables given to us included: gender: female or male, age: 1-92 years, stayed overnight: yes or no, visits: 1-38 per year, hours: 1-21, money: $98-$3674, and aliment: varies. The data collected was sample data since it is only a portion of the population that is representative. The sample size of this data is n= 120. I wanted to be very…

project. First, we measure financial performance as the profit margin generated by the project. The profit margin equates to the earnings before interest, taxes and amortization (EBITA) during the period of performance divided by the revenue during the same period. Second, we measure operational performance by extracting the client’s assessment of the contractor’s performance by the contractor from a U.S. Federal CPARS database in the evaluation areas of quality, cost control, management and…

3.12: Data Analysis process Overall, the objective of the research analysis is to try to answer the research questions formulated in Chapter 1. Accordingly, a conceptual framework and propositions have been developed from these questions, and justified in the literature review section. Therefore, the data analysis will be pursued to gather evidence pertaining to the several concepts identified. Quantitative data from the questiormaire survey will be analyzed by utilizing the Statistical…

Summary of Results The predictor variable, I would apply for a job with a female CEO or boss, had a skewness of -2.54 and a kurtosis of 4.57. The predictor variable, I would vote for a female president, had a skewness of -2.43 and a kurtosis of 5.57. The spearman’s correlation between the predictor variable, I would apply for a job with a female CEO or bass and the outcome variables, IAT scores, was 0.075 and had a significance of 0.726. The spearman’s correlation between the predictor…

Introduction The Framingham Heart Study was introduced in 1948, by the National Heart Institute, to provide research on cardiovascular disease (CVD) (Framingham Heart Study, n.d.). The original research participants included 5,209 men and men, aged 30 - 62, who shared patterns of cardiovascular disease development (Framingham Heart Study, n.d.). This study was first taken in Framingham, Massachusetts. The individuals participated in physical examinations, interviews about their lifestyle and…

CHAPTER 5 EXPERIMENTATION 5.1 Spur gear terms and concept Fig. 5.1 Terminology definitions for spur gears The radial distance from the pitch circle to the outside diameter is called as addendum. The radial distance between the pitch circle and the root diameter is called as dedendum. The distance of the arc along the pitch circle from one side of a gear tooth to the other is called as circular thickness. The length of the arc of the pitch circle from one point on a tooth to the same…

INDIVIDUAL DIFFERENCES IN MULTI-TASKING While there have been many studies that have examined the cognitive processes involved with performance when task switching and the resulting switch costs, scientists have paid little attention to the effect of individual differences such as gender, on the deficits in performance produced by multitasking and as a consequence, the empirical evidence for a causal relationship between gender and performance is sparse. This research is important in…

MIS 790 Comprehensive Exam Q1. To be able to build prediction models of botnet attacks, we had to decide information requirements. (a) What process did you use for identifying predictor variables for modelling botnet traffic flows? (b) What additional measures can be taken in terms of information (or data) gathering to further improve the accuracy of the prediction models? (a) I started with a literature survey and read articles to understand the problem and technical terms. To understand the…

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 to +1.5 and the kurtosis coefficient of a distribution taken in the range of -1.5 to +1.5 according to Tabachnick and Fidell (2013). For ordinal…
