Linear Regression Exercises 2025

Linear Regression Exercises Due 10/13/17 by 10 pm Simple Regression Research Question: Does the number of hours worked per week ( workweek ) predict family income ( income )? Using Polit2SetA data set, run a simple regression using Family Income ( income ) as the outcome variable (Y) and Number of Hours Worked per Week ( workweek ) as the independent variable (X). When conducting any regression analysis, the dependent (outcome) variables is always (Y) and is placed on the y-axis, and the independent (predictor) variable is always (X) and is placed on the x-axis. Follow these steps when using SPSS: 1. Open Polit2SetA data set. 2. Click on Analyze , then click on Regression , then Linear . 3. Move the dependent variable ( income ) in the box labeled “Dependent” by clicking the arrow button. The dependent variable is a continuous variable. 4. Move the independent variable ( workweek ) into the box labeled “Independent.” 5. Click on the Statistics button (right side of box) and click on Descriptives , Estimates , Confidence Interval (should be 95%), and Model Fit , then click on Continue . 6. Click on OK . Assignment: Through analysis of the SPSS output, answer the following questions. Answer questions 1 – 10 individually, not in paragraph form 1. What is the total sample size? 2. What is the mean income and mean number of hours worked? 3. What is the correlation coefficient between the outcome and predictor variables? Is it significant? How would you describe the strength and direction of the relationship? 4. What it the value of R squared (coefficient of determination)? Interpret the value. 5. Interpret the standard error of the estimate? What information does this value provide to the researcher? 6. The model fit is determined by the ANOVA table results ( F statistic = 37.226, 1,376 degrees of freedom, and the p value is .001). Based on these results, does the model fit the data? Briefly explain. (Hint: A significant finding indicates good model fit.) 7. Based on the coefficients, what is the value of the y-intercept (point at which the line of best fit crosses the y-axis)? 8. Based on the output, write out the regression equation for predicting family income. 9. Using the regression equation, what is the predicted monthly family income for women working 35 hours per week? 10. Using the regression equation, what is the predicted monthly family income for women working 20 hours per week? For this assignment, answer question 1 through 10 individually. DO NOT ANSWER IN PARAGRAPH FORM. Multiple Regression Assignment: In this assignment we are trying to predict CES-D score (depression) in women. The research question is: How well do age, educational attainment, employment, abuse, and poor health predict depression? Using Polit2SetC data set, run a multiple regression using CES-D Score ( cesd ) as the outcome variable (Y) and respondent’s age ( age ), educational attainment ( educatn ), currently employed ( worknow ), number, types of abuse ( nabuse ), and poor health ( poorhlth ) as the independent variables (X). When conducting any regression analysis, the dependent (outcome) variables is always (Y) and is placed on the y-axis, and the independent (predictor) variable is always (X) and is placed on the x-axis. Follow these steps when using SPSS: 1. Open Polit2SetC data set. 2. Click on Analyze, then click on Regression , then Linear . 3. Move the dependent variable, CES-D Score ( cesd ) into the box labeled “Dependent” by clicking on the arrow button. The dependent variable is a continuous variable. 4. Move the independent variables ( age , educatn , worknow , and poorhlth ) into the box labeled “Independent.” This is the first block of variables to be entered into the analysis (block 1 of 1). Click on the bottom (top right of independent box), marked “Next”; this will give you another box to enter the next block of indepdent variables (block 2 of 2). Here you are to enter ( nabuse ). Note: Be sure the Method box states “Enter”. 5.

Enhancing Quality and Safety 2025

Assessment 1 Instructions: Enhancing Quality and Safety For this assessment, you will develop a 3-5 page paper that examines a safety quality issue pertaining to medication administration in a health care setting. You will analyze the issue and examine potential evidence-based and best-practice solutions from the literature as well as the role of nurses and other stakeholders in addressing the issue. Health care organizations and professionals strive to create safe environments for patients however, due to the complexity of the health care system, maintaining safety can be a challenge. Since nurses comprise the largest group of health care professionals, a great deal of responsibility falls in the hands of practicing nurses. Quality improvement (QI) measures and safety improvement plans are effective interventions to reduce medical errors and sentinel events such as medication errors, falls, infections, and deaths. A 2000 Institute of Medicine (IOM) report indicated that almost one million people are harmed annually in the United States, (Kohn et al., 2000) and 210,000–440,000 die as a result of medical errors (Allen, 2013). The role of the baccalaureate nurse includes identifying and explaining specific patient risk factors, incorporating evidence-based solutions to improving patient safety and coordinating care. A solid foundation of knowledge and understanding of safety organizations such as Quality and Safety Education for Nurses (QSEN), the Institute of Medicine (IOM), and The Joint Commission and its National Patient Safety Goals (NPSGs) program is vital to practicing nurses with regard to providing and promoting safe and effective patient care. You are encouraged to complete the Identifying Safety Risks and Solutions activity. This activity offers an opportunity to review a case study and practice identifying safety risks and possible solutions. We have found that learners who complete course activities and review resources are more successful with first submissions. Completing course activities is also a way to demonstrate course engagement. Demonstration of Proficiency By successfully completing this assessment, you will demonstrate your proficiency in the following course competencies and assessment criteria: Competency 1: Analyze the elements of a successful quality improvement initiative. Explain evidence-based and best-practice solutions to improve patient safety focusing on medication administration and reducing costs. Competency 2: Analyze factors that lead to patient safety risks. Explain factors leading to a specific patient-safety risk focusing on medication administration. Competency 4: Explain the nurse’s role in coordinating care to enhance quality and reduce costs. Explain how nurses can help coordinate care to increase patient safety with medication administration and reduce costs. Identify stakeholders with whom nurses would need to coordinate to drive quality and safety enhancements with medication administration. Competency 5: Apply professional, scholarly, evidence-based strategies to communicate in a manner that supports safe and effective patient care. Communicate using writing that is clear, logical, and professional with correct grammar and spelling using current APA style. References Allen, M. (2013). How many die from medical mistakes in U.S. hospitals? Retrieved from https://www.npr.org/sections/health-shots/2013/09/20/224507654/how-many-die-from-medical-mistakes-in-u-s-hospitals. Kohn, L. T., Corrigan, J., & Donaldson, M. S. (Eds.). (2000). To err is human: Building a safer health system . Washington, DC: National Academy Press. Professional Context As a baccalaureate-prepared nurse, you will be responsible for implementing quality improvement (QI) and patient safety measures in health care settings. Effective quality improvement measures result in systemic and organizational changes, ultimately leading to the development of a patient safety culture. Scenario Consider the hospital-acquired conditions that are not reimbursed under Medicare/Medicaid, some of which are specific safety issues such as infections, falls, medication errors, and other concerns that could have been prevented or alleviated with the use of evidence-based guidelines. Choose a specific condition of interest surrounding a medication administration safety risk and incorporate evidence-based strategies to support communication and ensure safe and effective care. For this assessment: Analyze a current issue or experience in clinical practice surrounding a medication administration safety risk and identify a quality improvement (QI) initiative in the health care setting. Instructions The purpose of this assessment is to better understand the role of the baccalaureate-prepared nurse in enhancing quality improvement (QI) measures that address a medication administration safety risk. This will be within the specific context of patient safety risks at a health care setting of your choice. You will do this by exploring the professional guidelines and best practices for improving and maintaining patient safety in health care settings from organizations such as QSEN and the IOM. Looking through the lens of these professional best practices to examine the current policies and procedures currently in place at your chosen organization and the impact on safety measures for patients surrounding medication administration, you will consider the role of the nurse in driving quality and safety improvements. You will identify stakeholders in QI improvement and safety measures as well as consider evidence-based strategies to enhance quality of care and promote medication administration safety in the context of your chosen health care setting. Be sure that your plan addresses the following, which corresponds to the grading criteria in the scoring guide. Please study the scoring guide carefully so that you know what is needed for a distinguished score. Explain factors leading to a specific patient-safety risk focusing on medication administration. Explain evidence-based and best-practice solutions to improve patient safety focusing on medication administration and reducing costs. Explain how nurses can help coordinate care to increase patient safety with medication administration and reduce costs. Identify stakeholders with whom nurses would coordinate to drive safety enhancements with medication administration. Communicate using writing that is clear, logical, and professional, with correct grammar and spelling, using current APA style.
