Statistics as a tool in Psychology often being considered as difficult by students. This research aimed to examine effectiveness of comic as learning tool to improve Statistics achievement. Participants of this research were thirty undergraduate students and divided into three groups, Experiment (receive Statistics comic as treatment), Control (no treatment), and Comparison (receive conventional material). The effectiveness of comic were showed in changes in Statistics achievement test results (between group experimental design). The result showed significant changes on each group before and after learning. Experiment Group exhibited most impactful change that evidenced can improve students’ achievement in Statistics.
One of the key developments in psychological data analysis is the Bayesian implementation. This article aims to introduce Bayesian statistics application in psychological research. A data set of Marital Satisfaction and Positive Affect (n = 200) became an example to compare the regression results based on frequentist and Bayesian statistics. The data analysis examined the influence of positive affect on marital satisfaction. Based upon the prior information and observed data, results suggest that the average of the distribution of the posterior coefficient of positive affect is .31, with a deviation standard of .01 and a credible interval ranging from .30 to .33. The study’s results present the unique approach in interpreting the Bayesian result. This article also outlines diagnostic steps to obtain a robust Bayesian result and avoid misuse of Bayesian statistics. Finally, discussions cover the probability principle in Bayesian analysis and how to interpret its result to encourage Indonesian psychological scientists to implement Bayesian as an alternative to data analysis.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
