General Instructions For Each Assignment1 Attach Your Word Document Write the problem number and the problem title as a level one heading (Example – A.1.1: Chapter 2, Problem 2.1, Check the Completed Questionnaires) and then provide your response. Use level two headings with short titles for multi part questions (Example – A1.1.a, Short Title, A1.1.b, Short Title II, etc.) Use appropriate level headings for key elements of your discussion such as Research Questions, Hypotheses, Descriptive Statistics, Assumptions & Conditions, Interpretation, Results, and others. Your goal is to make your analysis easy to follow and logical. Ensure that all tables and graphs are legible and include a figure number. Carefully review your document prior to submission for formatting, flow, and readability. Keep in mind that running the statistical tests is only the first half of the challenge; you must be able to clearly communicate your findings to the reader!

Introduction The assignment focuses on the application of statistical techniques—such as scatterplots, correlation analyses, and regression models—to explore relationships among variables within a dataset related to college students. The overall goal is to demonstrate proficiency in data analysis, interpretation, and effective communication of results within an academic context. A6.1: Scatterplots to Check the Assumption of Linearity Research Question: Is there a linear relationship between student height and parent’s height? Null Hypothesis: There is no linear relationship between student height and parent’s height. Methodology: I generated scatterplots with regression lines (`Output 9.1a and 9.1b`) to visually assess linearity. These plots are included below and serve as visual confirmation of the assumption (see Figures 1 and 2). Findings: Both scatterplots indicate a positive linear trend, with data points generally aligning along the regression line, suggesting the assumption of linearity holds true. The scatterplot with the regression line (Figure 1) shows a clear upward trend, which confirms the appropriateness of subsequent correlation analysis. Descriptive Statistics: The mean and standard deviation for student and parent heights indicate mildly variable data, with no major outliers or skewness, satisfying the assumption of normality necessary for Pearson correlation. Figures Figure 1: Scatterplot of Student Height vs. Parent’s Height Figure 2: Scatterplot with Regression Line of Student Height vs. Parent’s Height A6.2: Bivariate Pearson and Spearman Correlations Research Question: What is the relationship between student height and parent’s height, as measured by Pearson and Spearman correlations? Null Hypothesis: There is no correlation between student height and parent’s height. Process: Using the descriptive statistics, I examined the distributions for normality, then computed both Pearson and Spearman correlation coefficients to assess linear and monot
