Hire Writer RSCH FPX 7864 Assessment 4 ANOVA Application and Interpretation Name Capella University RSCH FPX 7864 Quantitative Design and Analysis Prof. Name Date Outline for Data Analysis A single-factor analysis of variance (ANOVA) was performed to examine grades. The study looked at two variables: Section, which denotes various class sections, and Quiz 3, which indicates the number of correctly answered questions. Here, Section is the independent categorical variable, and the Quiz 3 scores are the dependent continuous variable. Research Inquiry The purpose of the study is to determine if there is a statistically significant difference in the average scores of different student groups on Quiz 3. The null hypothesis states that the average scores of different student subgroups on Quiz 3 are not significantly different. On the other hand, the alternative hypothesis indicates that there is a significant difference in the mean scores between the student groups. Evaluating Presumptions Verification of Assumptions Assessing the Equality of Variances (Levene’s Test) Test F df1 df2 p Levene’s 2.898 2.000 102.000 0.060 The Levene’s test produced a test statistic (F) of 2.898 with degrees of freedom (df) of 2 and 102, and a p-value of 0.060. When the p-value is equal to or less than the typical significance threshold (usually 0.05), it means rejecting the null hypothesis of equal variances, indicating a breach in the assumption of homogeneity. However, since the p-value obtained is above 0.05 (0.060), we cannot reject the null hypothesis, indicating that the assumption of homogeneity remains valid.

P-value adjusted for comparing a family of 3. RSCH FPX 7864 Assessment 4 ANOVA Application and Interpretation The table provides a detailed breakdown of the average scores attained by different student sections in Quiz 3. Statistical analysis using ANOVA showed a noteworthy variance in the mean scores across the sections (F (2,102) =10.951, p< .001). Nevertheless, further examinations through post hoc tests demonstrated no notable distinction (p > 0.05) between the scores of Section 1 and Section 3. Application In applied behavior analysis (ABA), ANOVA serves as a useful tool for assessing how various independent factors relate to one dependent variable, allowing for comparisons across multiple factors simultaneously. For instance, it can be utilized to assess strategies for reducing aggressive behavior among individuals, with the strategies being the independent variables and aggressive behavior being the dependent variable. Understanding how different treatment approaches influence aggressive behavior is crucial in improving patients’ quality of life and their interactions with others. References Andrade, C. (2019).

Hire Writer RSCH FPX 7864 Assessment 3 t-Test Application and Interpretation Name Capella University RSCH FPX 7864 Quantitative Design and Analysis Prof. Name Date Data Analysis Plan The plan for data analysis entails investigating how attending review sessions relates to final exam scores. This will be done by conducting a t-test and Levene’s test. The variables under consideration are ‘final’, which measures the number of correct answers on the final exam, and ‘review’, which indicates whether a student attended review sessions (coded as 1 for no attendance and 2 for attendance). Although ‘review’ is treated as a categorical variable, ‘final’ is treated as a continuous variable in this study. Testing Assumptions Examining the Equality of Variances (Levene’s Test) Test F df1 df2 p final 0.740 1 103 0.392 Levene’s test was employed to evaluate whether the variations among the groups were equal. With a p-value of 0.392, the results indicate that there is no notable distinction in variances between students who participated in review sessions and those who did not (Kim, 2015). Findings & Analysis T-Test for Unrelated Groups t df p -0.410 103 0.682 Descriptive statistics for each group: Group N Mean SD SE Coefficient of variation Participated in the review meeting. 55 61.545 7.356 0.992 0.120 Missed the review session. 50 62.160 7.993 1.130 0.129 RSCH FPX 7864 Assessment 3 t-Test Application and Interpretation The findings from the t-test indicate that there is no notable distinction in the final exam scores between students who participated in review sessions and those who didn’t (p = 0.682). As a result, there is insufficient evidence to discard the null hypothesis. Statistical Conclusions The research findings suggest that there isn’t a notable variance in final exam results between students who participated in review sessions and those who didn’t. Consequently, it seems that attending review sessions doesn’t lead to improved performance in tests. Application In areas such as applied behavior analysis (ABA), researchers often employ the independent samples t-test to assess the effectiveness of various therapeutic approaches in addressing behavioral challenges. This statistical tool helps in identifying which interventions are most beneficial for individuals with developmental disabilities. References Capella University. (n.d.). 7864 Course Study Guide.

Hire Writer RSCH FPX 7864 Assessment 2 Correlation Application and Interpretation Name Capella University RSCH FPX 7864 Quantitative Design and Analysis Prof. Name Date Plan for Analyzing Data Exploring how past academic achievements relate to current performance provides valuable insights into students’ learning journeys. While many factors contribute to student success, their prior GPA serves as a general measure of academic background and abilities. This examination concentrates on four ongoing factors: Quiz 1, GPA, Final exam, and Total points. Ultimate Correlation Analysis Research Inquiry: Examining the Relationship Between Total Class Points and Final Exam Correct Answers Null Assertion: Lack of Significant Correlation Between Total Class Points and Final Exam Correct Answers Alternative Proposition: Identification of Significant Correlation Between Total Class Points and Final Exam Correct Answers Correlation Between GPA and Quiz Performance Investigation Inquiry: Does a Student’s Prior GPA Relate to Quiz 1 Performance? Null Hypothesis (H₀): Absence of a Substantial Link between a Student’s Prior GPA and Quiz 1 Accuracy. Alternate Hypothesis (H₁): Existence of a Meaningful Correlation between a Student’s Previous GPA and Quiz 1 Precision. Testing Assumptions Let’s examine our assumptions. Looking at the descriptive statistics in Table 1, we observe the skewness and kurtosis levels for GPA and the final exam. GPA displays a skewness of -0.22 and a kurtosis of -0.69, while the final exam exhibits values of -0.34 and -0.28 respectively. The skewness values for both metrics lie within the -1 to 1 range, indicating relatively balanced distributions. With skewness falling between -0.5 and 0.5, we can infer a nearly symmetrical distribution, suggesting that our data might follow a normal distribution. Results & Interpretation (Table 2)   GPA Total Quiz1 Final Mean 2.862 100.086 7.467 61.838 Std. Deviation 0.713 13.427 2.481 7.635 Skewness -0.220 -0.757 -0.851 -0.341 Kurtosis -0.688 1.146 0.162 -0.277 Correlation Matrix In Table 2, a minor positive correlation (r=0.152) exists between GPA and Quiz 1. With 104 degrees of freedom and a significance level of p=0.01, the observed p-value (0.212) is greater than 0.01, indicating nonsignificance. The effect size suggests Quiz 1 explains only 2% of GPA variability, hence failing to reject the null hypothesis. Pearson’s Correlations   Quiz1 GPA Total Final Quiz1 — 0.152 0.121 0.499 GPA 0.152 — 0.318 0.379 Total 0.121 0.318 — 0.875 Final 0.499 0.379 0.875 — The strongest correlation (r=0.875) is between ‘final’ and ‘total’ variables, statistically significant with a p-value of 0.000. ‘Final’ explains 76% of ‘total’ variability. A moderate correlation (r=0.379) exists between GPA and Final, significant with a p-value of 0.000. Final explains 14% of GPA’s variability. Statistical Conclusions While no significant correlation exists between GPA and Quiz 1, strong correlations are found between ‘final’ and ‘total’ scores and between GPA and Final scores, implying meaningful linear relationships.

Hire Writer RSCH FPX 7864 Assessment 1 Descriptive Statistics Name Capella University RSCH FPX 7864 Quantitative Design and Analysis Prof. Name Date Introduction Descriptive statistics are fundamental in summarizing data sets, whether representing an entire population or a sample subset. This analytical approach entails measures of central tendency like the mean, median, and mode, alongside Variability metrics like standard deviation, variance, range (minimum and maximum values), kurtosis, and skewness are utilized to gauge the spread or dispersion of data points (Hayes, 2023). Histograms, graphical representations showcasing the frequency distribution of individual variables, serve to visually grasp the distribution patterns of dependent variables (What is a histogram chart, 2023). Section 1: Utilizing Histograms for Visual AnalysIS Visualizing Data Distributions Final Introductory Level Elevated Tier 80-85 80-82 83-85 85-90 86-88 89-90 90-95 91-92 93-95 95-100 96-97 98-100 In Section 1, there are two distinct histograms displaying student scores divided into different brackets. The vertical bars in each histogram represent the number of students falling into specific score intervals, offering a visually understandable depiction of the data gathered (Definition of a Histogram Chart, 2023). Section 2: Compute Measures of Central Tendency and Variation Descriptive Statistics   GPA Quiz3 Mean 2.862 7.133 Std. Dev. 0.713 1.600 Skewness -0.220 -0.078 Std.

Error of Kurtosis 0.467 0.467 RSCH FPX 7864 Assessment 1 Descriptive Statistics The mean, frequently employed to depict central tendency, indicates the average value for the GPA (M = 2.862) and Quiz 3 (M = 7.133) datasets. Standard deviation, providing a more precise estimate of dispersion, is vital for comprehending the spread of scores concerning the mean (Trochim, 2023). For GPA (SD = 0.713) and Quiz 3 (SD = 1.600), these values are presented. Skewness and kurtosis, representing the shape of the frequency distribution, fall within the acceptable range of -1 to +1, indicating normality for each distribution (Quality Advisor, 2023).
