SEMINAR WORKSHOP: AN INTERVENTION FOR STATISTICAL ANALYSIS FOR RESEARCH

Education

The study, “Seminar Workshop: An Intervention for Statistical Analysis for Research”, aimed to develop a seminar workshop to enhance the statistical proficiency of senior high school students in a coastal school. Using a mixed-method research design, the study involved 38 Grade 12 students and employed a pretest-posttest approach to assess changes in their skills. Instruments included are researcher-made survey questionnaire, pre- and post-tests, proposal evaluation rubrics, and a Focus Group Discussion Interview Guide. Results showed a significant improvement in statistical analysis after the seminar. The mean scores rose from 9.37 in the pretest to 15.13 in the posttest, with a mean gain 5.76. A paired t-test yielded a t-value of 8.20, confirming statistically significant improvement. The Cohen's d value of 1.45 indicated a large effect size, emphasizing the seminar’s impact. Students notably improved in hypothesis testing, sampling techniques, and statistical analysis using both manual methods and software tools like JAMOVI. Qualitative data from focus group discussions revealed that participants found the seminar engaging and practical, with strengths in delivery and interactive sessions. Observers highlighted its role in addressing gaps in textbooks and existing resources. Suggestions for improvement included extending the seminar’s duration and incorporating more individual activities. The study concluded that the seminar effectively enhanced statistical skills, combining theoretical and practical learning. Educators and administrators are encouraged to adopt a similar workshop to prepare students for research projects and deepen their understanding of statistical concepts.
