MAT FPX 2001 Assessment 5 Evaluating Studies Name Capella University MAT FPX 2001 Statistical Reasoning Prof. Name Date Evaluating Studies Purpose and Summary of the Selected Gallup Poll The Gallup poll chosen for evaluation is titled “U.S. Employee Engagement Needs a Rebound in 2023” (Gallup, 2023). This study focuses on the population primarily comprising workers from various organizations. Conducting a survey among workers from different organizations is vital to ensure the selected population is representative and to generalize the findings. The study explores the impact of employee interaction on business outcomes, revealing a 36% decline in employee engagement over the past decade. The Gallup survey collected data from a random sample of 15,000 U.S. full and part-time employees. Results indicate that organizations are adapting to new hybrid work arrangements, with 21% of remote-ready jobs functioning on-site. Moreover, 53% of employees work in hybrid arrangements, while 26% work remotely. This stabilization in work patterns brings predictability but demands a high level of coordination. To maintain engagement, the organization relied on its culture and values, guiding business decisions and fostering strong connections between managers and employees. Appropriateness of Sample The Gallup poll highlights key results, including a decrease in the ratio of actively engaged to disengaged workers in the U.S. from 2.1 to 1 in 2021 to 1.8 to 1 in the current year, marking the lowest ratio of disengaged workers in the United States. The margin of error, influenced by sample size, impacts the fall of the valid population parameter. Larger samples reduce the margin of error, providing more detailed information and mitigating random sampling errors. Various factors, such as data variations and confidence levels, must be considered when interpreting survey results (Story & Tait, 2019). Rationale for Sampling Technique The chosen sampling technique depends on research questions, population traits, and available resources. Random sampling, applied in this Gallup survey, ensures an unbiased representation of the entire population, making it superior to cluster, stratified, and simple sampling approaches. The study focuses on randomly sampling the working population, assessing elements such as customer service and productivity in the workspace. Comparison With Other Techniques Random sampling, applied in this Gallup survey, is considered superior to cluster, stratified, and simple sampling. Unlike stratified sampling, which may not be representative of the overall population, random sampling ensures each sample is equally observed, providing unbiased representation of the entire population (Lakens, 2022). Interpretation of Confidence Interval Confidence intervals indicate the range of values suggesting the probability that the population parameter lies within that range. In this survey, confidence intervals highlight variations in engagement among different age groups. For instance, young workers experienced a four-point decrease in engagement, while active disengagement increased by four points. Effect of Study Design on Margin of Error Random changes in the sampling process influence margins of error, with larger sample sizes leading to smaller margins. Modifications in the study design can alter marginal errors, emphasizing the importance of relevant samples to accurately reflect the population (Etikan & Babatope, 2019). Impact of Question-Wording Question wording significantly influences participant responses, with inaccurate phrasing leading to unreliable results. Careful selection of neutral and clear questions ensures unbiased participant responses, contributing to the validity of survey outcomes (Henriques et al., 2019). Impact of Question-Wording on Statistical Results The phrasing of questions directly affects statistical outcomes, with various question types yielding different insights. The survey in question explores employee engagement, emphasizing the importance of selecting wording that aligns with desired survey outcomes (DeJonckheere & Vaughn, 2019). Evaluation of Biasness Determining the presence of bias in the study is challenging, but the chosen random sampling method aims to minimize bias. To ensure an unbiased survey, the study utilizes random sampling (Kyriazos, 2018). Avoidance of Biasness Careful consideration of question wording and survey design helps mitigate biases. The study employs a well-constructed questionnaire with neutral questions to obtain precise answers, reducing the impact of potential biases (Boutron et al., 2019). Conclusion In conclusion, the study “U.S. Employee Engagement Needs a Rebound in 2023” provides valuable insights into the engagement levels of U.S. workers. Employing random sampling and avoiding biases, the study emphasizes the importance of working in a hybrid arrangement. The use of descriptive statistics enhances the evaluation of both quantitative and qualitative data, contributing to the reliability of the study’s findings. References Boutron, I., Page, M.
