EPsy 8271 Reflection Paper – Week 6 Jihoon Ryoo 1 Wilkerson, M. and Olson, M.R. (1997). Misconceptions About Sample Size, Statistical Significance, and Treatment, The Journal of Psychology, 131(6), 627-631. It was good to reveal misconceptions that many students are struggling in statistical inference. However, it does not seem that it discussed the problems related to misconception seriously. The design in this paper was not supportive what statistics community faced with statistical inference issue. The research method seemed to be limited in terms of population where their assertion can be generalized. Haller, H. and Krauss, S. (2002). Misinterpretations of Significance: A Problem Students Share with Their Teachers? Methods of Psychological Research Online, 7(1).

(2007). Students’ misconceptions of statistical inference: A review of the empirical evidence from research on statistics education, Educational Research Review, 2, 98-113 They summarized students’ misconceptions of statistical inference same as title. Many issues were brought in one paper. It was helpful to summarize what I need to consider as statistics educator what barriers are in misconceptions of statistical inference. However, I had questions like: Was there any solution? Do I have to read all articles to find solution related statistical inferential problem? There was a lack of suggestion compared with issues
