Abstract

          The objectives of this research were (1) to develop learning media using the Canva program on the selection of t-test and ANOVA. (2) To compare the academic achievement before and after studying on the selection of t-test and ANOVA. And (3) to study the satisfaction of students after learning on the selection of t test and ANOVA. The sample group in this research was 32 second-year public health students, class 1, selected by cluster sampling. The achievement test passed the quality examination with IOC values ​​ranging from 0.67 to 1.00, difficulty values ​​(p) ranging from 0.41 to 0.69, discrimination power (r) ranging from 0.44 to 0.94, and a KR20 reliability value of 0.89. The research instruments were (1) learning media using the Canva program on the selection of t-test and ANOVA, (2) quality assessment of learning media, (3) learning Achievement Test, and (4) assessment of satisfaction with learning media. The statistics used in this research were mean, standard deviation, and t-test. The research results found that (1) the quality of learning media using the Canva program was at the highest level of appropriateness. (2) after learning about the selection of t-test and ANOVA using learning media, the students had significantly higher academic achievement than before learning at a statistical level of .05, and (3) students are most satisfied with the learning media.
