Whether In A Scholarly Or Practitioner Setting Good Research And Data
Perform an article critique on t tests, including responses to specific questions regarding the research design, appropriateness of the t test used, data display, standalone nature of the results, and reporting of effect size. The critique should be 3 to 5 paragraphs, written in APA format, and include evaluation of whether the authors' choices and data presentation are appropriate and meaningful. Use credible scholarly sources, including the provided course texts and additional research as needed, to support your analysis.

In the realm of research, particularly within social sciences and applied disciplines, the use of t tests is prevalent for analyzing differences between groups or conditions. The article selected for critique employed a quasi-experimental research design to compare two independent groups on a specific outcome measure. The authors utilized an independent samples t test to analyze the differences observed between these groups, which is appropriate given the study's aim to compare means from two separate samples. The choice of this test aligns with the research question, which seeks to determine if there is a statistically significant difference in the dependent variable across the two groups, assuming normal distribution and homogeneity of variances.
The authors displayed the data transparently by including means, standard deviations, and sample sizes for each group, which provides a clear overview of the data distribution and variance. Moreover, the results are presented both in table and narrative form, which enhances readability and understanding independent of the statistical analysis. This presentation allows readers to interpret the outcomes without having to interpret raw statistical output alone, although the inclusion of confidence intervals would further strengthen the interpretability.
In terms of statistical significance, the authors reported the t statistic, degrees of freedom, and p-value, demonstrating whether the null hypothesis could be rejected. Importantly, they also reported the effect size, specifically Cohen's d, which quantifies the magnitude of the difference observed. The reported effect size was medium, indicating a practically meaningful difference between groups. Reporting effect size is particularly valuable as it contextualizes the p-values and provides insight into the clinical or practical significance of the findings, aligning with best practices in statistical reporting (Frankfort-Nachmias, Leon-Guerrero, & Davis, 2020). Overall, the authors’ use of the t test appears appropriate, data are presented transparently, and the inclusion of effect size adds valuable context to the statistical findings.
