The Effects of Instruction Using statskingdom.com on Learning Achievement and Satisfaction of Engineering Students in the Lesson of Simple Linear Regression and Correlation

Abstract

This research aims to: (1) compare the learning achievement of engineering students in the Statistics for Engineering course on the topic of Simple Regression and Correlation Analysis before and after receiving instruction through the integration of an online statistical data analysis website; (2) compare the students’ achievement score with the 60% criterion; and (3) study the students' satisfaction with the learning experience after using the online statistical data analysis website.  The target population consisted of 42 students enrolled in the Statistics for Engineering course in the Mechanical Engineering Program, Faculty of Engineering, Thaksin University, during the 2024 academic year. The research instruments included a 9-hour instructional plan, two parallel forms of pretest and posttest achievement tests, and a satisfaction questionnaire. The results revealed that the students’ posttest scores () were significantly higher than their pretest scores (), with an average improvement of more than 50%. Twenty-five students (59.5%) achieved scores above the 60% criterion. Moreover, the overall level of student satisfaction toward the instruction using the online statistical data analysis website was rated at the highest level ().
