Descriptive Quantitative Study

Alignment of Concepts, Theory, and Research Design

Alignment entails consistency in using and relating concepts, theories, and methodology throughout a study. The article’s concepts include physical education, overweight and obesity, and energy expenditure among school-goers. The paper lacks a distinctive theoretical framework but has a solid research design that seeks to describe the concepts and identify their relationships. The consistency is evident from the background, where the authors introduce the concepts and their significance to the methodology, where they describe the process of evaluating them (Kahan & McKenzie, 2015). Hence, the design and concepts align.


The authors described their methodological approach by exploring the sampling process, including the inclusion/exclusion criteria. The criteria help define the study’s target population (Patino & Ferreira, 2018). Next, the researchers described the characteristics of physical education (PE) classes. This definition helps the audience understand the variations in minimum activity threshold for different states and how that might affect the results. Finally, the authors presented the necessary formulas and data calculations, crucial to understanding the intended data interpretation process. Thus, the methodology explanation is clear and adequate.

Appropriateness of Approach

The descriptive quantitative method is appropriate for this study since it facilitates data comparison (Office of Research and Doctoral Services, 2015). The researchers could compare various metrics, such as annual energy expenditure across different states. The researchers could also identify trends, such as how energy expenditure changes according to grade or gender. Therefore, the descriptive quantitative approach allowed the researchers to collect comprehensive data and describe their phenomenon.

Proof of Use of Descriptive Approach

The study demonstrated various features of descriptive quantitative research. First, there is no control (McCombes, 2020). The researchers do not attempt to control any variable but instead focus on observing, measuring, and analyzing the phenomenon without interfering with it. Descriptive studies are also cross-sectional (Gray & Grove, 2021), which is the case with the current one. The data collection occurs instantaneously, and there is no follow-up to check how it changes in the future. Therefore, the study complies with the requirements of descriptive quantitative research.

Data Collection Process

The data collection process description is shallow. For instance, the authors do not show how they used the National Association for Sport and Physical Education (NASPE) guidelines to estimate energy expenditure. There is also no description of their sources for the state-based data. The only full data collection description involves the step-wise energy expenditure calculation procedure. Therefore, the overall data collection description is insufficient to replicate the study.

Data Analysis

The researchers used a graphical/tabular method for data analysis. They grouped the data into logical groups, such as age, gender, and reporting authority (NASPE or State). Then, they constructed appropriate tables and cumulative graphs to present the same data. Hence, the study does not use complex analytical processes and relies on basic arithmetic knowledge.


The study highlights some essential components of descriptive studies. However, there are significant gaps, such as the lack of a systematic data collection approach. The research also does not provide demographic data of the participants. Therefore, it is difficult to tell the number of participants for each category. Finally, the study lacks comprehensive data analysis. It would have been more informative if the authors had performed statistical or regression analysis since one could tell the potential and actual impact of PE on childhood obesity. These shortcomings generate the following questions: how important is a systematic data collection approach to descriptive quantitative studies? Are participants’ particulars essential to determining the clinical significance of descriptive research findings? How do analytical methods enhance the effectiveness of descriptive quantitative studies?
