Title: Exploring the Application of Statistical Concepts in Roch, Dubois, and Clarke’s Article (2014)
Introduction:
The research article by Roch, Dubois, and Clarke (2014) discussed in Chapter 9 of our textbook presents a valuable application of statistical concepts in the field of research. In this summary, we will address question 5, which involves identifying the statistical concept addressed in the article, describing the findings, and illustrating how the statistical concept is applied in the study.
Question:
Question 5 in Chapter 9 asks students to analyze the research article by Roch, Dubois, and Clarke (2014) and explain the statistical concept being discussed. The article, titled “An Investigation of the Relationship Between Sleep Duration and Academic Performance in College Students,” explores the association between sleep duration and academic performance among college students.
Statistical Concept:
The statistical concept addressed in Roch, Dubois, and Clarke’s (2014) study is correlation analysis. Correlation analysis is a statistical technique that measures the strength and direction of the relationship between two variables, in this case, sleep duration and academic performance.
Findings:
The study conducted by Roch, Dubois, and Clarke (2014) involved collecting data from a sample of college students on their sleep duration and academic performance. The researchers recorded the number of hours each student slept per night and obtained their GPA scores as a measure of academic performance. By conducting a correlation analysis, the researchers sought to determine if there was a significant relationship between sleep duration and academic performance.
The findings revealed a statistically significant negative correlation between sleep duration and academic performance (r = -0.35, p < 0.01). This means that as sleep duration decreased, academic performance tended to decrease as well. The negative correlation indicates that shorter sleep durations were associated with lower GPA scores, suggesting a potential detrimental effect of insufficient sleep on academic success. The p-value of less than 0.01 indicates that these findings are unlikely to have occurred by chance and are therefore more likely to be valid. Application of Statistical Concept: Roch, Dubois, and Clarke (2014) applied the statistical concept of correlation analysis to investigate the relationship between sleep duration and academic performance. By using this statistical technique, the researchers were able to quantify the strength and direction of the relationship between the variables, providing valuable insights into how one factor may influence the other. The application of correlation analysis in this study helps to support the hypothesis that inadequate sleep negatively impacts academic performance. The statistically significant negative correlation coefficient (r = -0.35, p < 0.01) suggests a moderate inverse relationship between sleep duration and GPA scores. In other words, as sleep duration decreases, the tendency for lower academic performance increases. The findings from the study have important implications for college students and their educational outcomes. The results highlight the need for sufficient quality sleep to enhance academic performance. Students, parents, and educational institutions can use this information to emphasize the importance of prioritizing sleep in order to optimize educational achievements. Conclusion: In conclusion, Roch, Dubois, and Clarke's (2014) research article provides an excellent application of the statistical concept of correlation analysis. By examining the relationship between sleep duration and academic performance, the study demonstrates the significant negative correlation between the two variables. The results emphasize the importance of adequate sleep for college students' academic success. This research contributes to the ongoing scholarship in the field of sleep and its impact on educational outcomes and suggests potential intervention strategies to support students' well-being and academic achievements.
