NUR 705 Assignment 3.1 Levels of Measurement in Articles
Paper Instructions
Introduction
The goal of this assignment is to evaluate the independent and dependent variables in a selected article.
Assignment Guidelines
1. Review the article Physical and Psychological Effects of a 12-Session Cancer Rehabilitation Exercise Program (Links to an external site.).
2. Prepare a written analysis of the article that answers the following questions:
- What are the independent variables and dependent variables in the selected article?
- What levels of measurement are the variables?
- How do they measure each variable?
3. Your analysis should also include an introduction that summarizes independent and dependent variables in the article and a conclusion that provides closure to the topic.
4. Maximum of one page.
5. Include a reference citation at the end of your paper.
Submission
Submit your assignment and review full grading criteria on the Assignment 3.1 Levels of Measurement in Articles page.
In Week 4, you will submit your critique of the article you selected in Assignment 2.1 Systematic Article Review—Part I. Your critique will be a written analysis evaluating the selected article.
Use the 2009 Prisma checklist (PDF) (Links to an external site.) as a starting point for evaluating your chosen systematic review. This will be turned in with your paper.
Write a two – three-page pager, using APA format that includes the following:
- Start your paper with a short introduction of the purpose of the paper.
- Write a short summary on the topic of the systematic review.
- Write to how the authors determined which studies they were going to include in the systematic review.
- Was there a table included in the article? If so, what caught your eye as important comparisons to take away from the information presented?
- Consider the limitations of the systematic review. Did the authors identify limitations of their review? After reading the review, what suggestions would you have to improve their methods?
- Conclude your paper.

Sample Answer
A dependent variable is a variable whose value depends on the value of one or more other variables (the independent variables). In other words, the dependent variable is a function of the independent variables (Diel et al., 2021). For example, in the study, levels of depression, fatigue, aerobic endurance, muscular strength, and quality of life (QOL) among patients with cancer (the dependent variable) depended on the level of participation in a 12-session exercise program (independent variable).
From the study, A 12-session cancer rehabilitation exercise program was found to result in significant improvements in self-reported physical and psychological functioning, including vitality, fatigue, anxiety, and depression. The study also showed a decrease in IL-6, TNF-α, and CRP levels (indicators of inflammation) (Smith & Broomhall, 2016).
The results of this study suggest that a 12-session cancer rehabilitation exercise program is an effective intervention for improving the self-reported physical and psychological functioning of cancer patients. It is important to note that the results of this study are correlational; therefore, it cannot be determined whether the improvements in self-reported physical and psychological functioning were due to the exercise program or some other factor.
From the study, the independent variable is the level of participation in a 12-session exercise program while the dependent variables include levels of depression, fatigue, aerobic endurance, muscular strength, and quality of life (QOL) among patients with cancer. The level of measurement is a way of classifying data according to the type of information they represent.
There are three levels of measurement nominal, ordinal, and interval/ratio. From the above case, the dependent variable is ordinal while the independent variable is nominal. For the independent variable, the measurement was done during a 6- to 10-week exercise program that occurred twice weekly (Smith & Broomhall, 2016).
In particular, the six-minute walk test was conducted using the track in the exercise room; each lap was 90 feet. For the dependent variable, aerobic endurance was measured with the six-minute walk test (Smith & Broomhall, 2016). On the other hand, Muscular strength was measured with the hand grip strength test and muscular endurance with the 30-second sit-and-stand test while depression was measured using PHQ-9 scale.
In conclusion, from the study, the independent variable had significant impacts on the dependent variables. This study aimed to test the hypothesis that participating in a 12-session exercise program will improve depression, fatigue, aerobic endurance, muscular strength, and quality of life (QOL) in patients with cancer.
