3. PROBLEM & RESEARCH SETTING 3.1 Problem Statement Numerous research studies have been conducted by the CII and also other FEP researchers with regards to the implementation and critical importance of front end planning in project success. But there are very few studies that provide quantifiable statistical data supporting FEP adoption. CII has published data analysis for FEP data which analyses the relationship between project PDRI scores and scope definition, and project cost, schedule and…

indicate a number of weak positive relationships between CCA results and amount of time spent participating in extracurricular activities. The majority of the p-values were > 0.10 which indicates that the data appear to be consistent with the null hypothesis, which is seen in Tables 6 and 7. The p-value of 0.0087 provides solid evidence to support the present research when comparing the amount of time males spent participating in other activities when compared to the twelve week CCA.…

csv. HYPOTHESIS The goal was to compare the hourly wages of college-educated and non-college educated people. The null and alternative hypothesis is specified below: Null Hypothesis, H0: There is no difference in the average hourly wages between college graduates and non-college educated people. Alternative Hypothesis, H1: There is a difference the average hourly wages between college graduates and non-college educated people It is clear from the specification of the alternative hypothesis…

t-test of Male and Female Exam Results Equal variances were assumed as male and female variances are similar. The null hypothesis, that the difference between male and female results was 0, was not rejected (0.50 is greater than 0.05 at 5% significance) for the alternative hypothesis, that the difference between male and female results would be greater than 0. Therefore, there is insufficient evidence that males outperform females on exams. The effect…

has a nominal scale with 1, 2, and 3. The quiz 3 variable, or the outcome variable, uses a ratio scale of measurement for each variable. 3. The sample size of the data consists of 105 students who range from first year to fourth year in college. Testing Assumptions 1.…

Explore Correlation and Regression Using the explore function within SPSS gives a clearer view of how the data is represented. The explore function helps to assess the variables within the investigation by visually identifying various aspects of the data, therefor revealing the true nature of the data (Field, 2013). For example, the data in the Chamorro-Premuzic.sav file can be evaluated in a number of ways, for example analyzing the data based on the gender grouping allow one to visualize the…

In this project, I will analyze the problem of gender inequality in terms of labor income. This problem is important in our society because people with same background and same experience should be treated the same in the same working environment. Women should not be judged based on their biological gender. The data sample used in this project is working individuals between ages 25 and 54 from Current Population Survey, 2012. Sample size contains 999 observations. I will first discuss the…

We failed to find any data to support our hypothesis because there were no statistically different values or results. In addition, all the messages were the same because we did not find any statistically significant data or results. Further tests could have been done with an increased sample size…

The first opposing article does not provide significant evidence that preworkout supplementation is safe, and can therefore be interpreted as inconclusive. The authors did not provide a specific hypothesis. In this study, researchers conducted two separate trials to determine the safety and effectiveness of a PWS on healthy men and women. The first part of the trial was meant to specifically research the safety of using PWS. The second trial took a closer look at the actual impact preworkout…
