Statistical significance

significant data or results. Further tests could have been done with an increased sample size that could possibly yield at statistically significant p-value. By modifying the messages for future tests, we could be able to increase the statistical significance of the results. We could create a very bland message with all the writing the same size black and white, boring font, then we could create a colorful message with different fonts and font sizes that is appealing to the eye. It is…

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 change performance. Even though the it is evident that…

Statistical Analysis: Means and standard deviations were calculated for body composition (body fat), power (vertical jump, Broad jump, average power), speed (20M sprint), Lower limb strength (1RM Squat) and endurance (12min run) for each training group. A factorial repeated-measures ANOVA was used to examine significance between the independent variables of testing (pre- and post-) and groups (control and chest and hip deep) on the dependent variables. Statistical significancewas set a priori…

Birth weight exceeding the 94th percentile showed statistical significance. Feeding problems a few times a week at 6 months and SGA were not statistically significant, indicating that they were not interpreted accurately in reference to the measures of association. The relative risk for SGA was 0.5, which could…

sufficient statistical evidence at the 5% significance level (t=-3.981 and tcrit=-2.021) to reject the null hypothesis that the mean of D3 is not significantly different than the mean of D1. Consequently, another two-sample Pooled t test was used to test the hypothesis that the mean delivery speed of deliveryman 4 (D4) is not significantly different from mean delivery speed of deliveryman 1 (D1) at a 5% level of significance and 39 degrees of freedom. There was sufficient statistical evidence…

3.8.2 Geary’s C Another measure of spatial autocorrelation is Geary’s C statistic which ranges from 0 to 2 where 0 signifies maximum positive spatial autocorrelation or clustering, 1 signifies no autocorrelation or randomness and 2 signifies maximum negative autocorrelation or dispersal. If the values of Geary’s C are low it indicates positive spatial autocorrelation and if the values are high it indicates negative spatial autocorrelation. The calculation is similar to Moran’s I but here the…

of collecting and analyzing numerical data in large quantities, especially for the purpose of inferring proportions in a whole from those in a representative sample. The following paper seeks to provide basic knowledge in some specific areas of statistical data analysis. Descriptive statistics Descriptive statistics is the term given to the analysis of data that helps describe, show or summarize data in a meaningful way. Descriptive statistics do not allow us to make conclusions beyond the data…

There is little doubt public education in the United States is under intense scrutiny from the American public in recent years. In Mississippi, years of negative student outcomes have created a great deal of negative publicity for the state’s public schools. It is important for educators, whether at the district level, research level, or policymaking level, to continue to study available data to identify areas of weakness with the realm of education and work collaboratively to remedy those…

This assignment will address a one way ANOVA between the variables of section and guiz 3 from the grades.sav data sample Data File Description 1. The context of the data set is based on a sample size of 105 students that states their first and last names and are assigned separate id numbers. The sample contains variables that include the variables to be addressed in this assignment. 2. The variables used in this are section and quiz 3. The section variable, or the predictor variable has a…

Proficiency was measured on a Likert scale from (1-7), and comprehensibility was comprised of five 7-point bipolar scale. 7. Describe the statistical tests that the researcher(s) used to analyze the data he/she/they collected. Identify which test was used for which question/hypothesis. Ignore procedures that are not related to the question/hypothesis Statistical test that were used: a. Standardized coefficient Beta b.…
