Unit 9 Assignment 1: Journal Article Summary

U09a1 Unit 9 Assignment 1 Journal Article Summaryfor This Assignme

For this assignment, you will identify a published research article in your discipline that reports empirical data using statistical tests such as correlation, t-test, or one-way ANOVA. The article must be from peer-reviewed sources and must involve data-based research, excluding purely descriptive or qualitative studies. Select a journal article related to your career specialization that demonstrates the use of these statistical tests. The purpose is to familiarize yourself with professional research literature, practice interpreting statistical results, and develop concise scientific writing skills.

You will write a summary of the article in a maximum of 600 words using the provided DAA Template. The summary should include a brief description of the study, definitions of the variables with their measurement scales, sample size, and relevance to your field. Additionally, evaluate the assumptions of the statistical tests, state the research questions, hypotheses, report the statistical results following APA style, and discuss the conclusions, strengths, and limitations of the study. Proper citation and paraphrasing are required, avoiding extensive direct quotes.

Paper For Above instruction

In the selected empirical research article, the authors explore the relationship between variables pertinent to my career in psychology. The study investigates how self-efficacy (predictor variable, measured on a continuous scale) influences academic achievement (outcome variable, measured through standard scores). The sample consisted of 150 undergraduate students from a university setting. The relevance of this research to my career lies in understanding factors that impact student success, which can inform interventions and educational practices in clinical and counseling psychology.

The statistical analysis employed was a correlation coefficient, which examines the degree of association between self-efficacy and academic achievement. The assumptions underlying the Pearson correlation include linearity, normality of the variables, and homoscedasticity. The article reports that preliminary analyses were conducted to check these assumptions. For instance, scatterplots indicated linear relationships, and normality tests showed no significant deviations, although the article did not specify these details extensively. The lack of thorough reporting on assumption testing is a limitation, as it affects the validity of the correlation findings.

The research question posed by the authors was: "Is there a significant relationship between self-efficacy and academic achievement among undergraduate students?" The null hypothesis stated that there is no correlation between the two variables, while the alternative hypothesis proposed that a significant correlation exists.

The results revealed a Pearson correlation coefficient of r = 0.45, with degrees of freedom (df) = 148, and a p-value of less than 0.001. This indicates a moderate positive correlation between self-efficacy and academic achievement. The effect size, as indicated by Cohen's guidelines, suggests a meaningful relationship. The p-value being less than 0.05 leads to the rejection of the null hypothesis, supporting the conclusion that higher self-efficacy is associated with better academic performance.

The conclusion of the study confirms that self-efficacy significantly predicts academic achievement in this population. The findings align with Bandura's social cognitive theory, emphasizing the importance of self-perceptions in behavioral outcomes. The strength of this study lies in its focus on a relevant population and clear statistical reporting. However, limitations include the reliance on self-report measures for self-efficacy, which may introduce bias, and the cross-sectional design that prevents causal inference. Future research could incorporate longitudinal designs and experimental manipulations to better understand causal relationships.
