Handling Missing Data in Research Studies of Instructional Technology.
Oh, Jeong-Eun
Missing data is an important issue that is discussed across many fields. In order to understand the issues caused by missing data, this paper reviews the types of missing data and problems caused by missing data. Also, to understand how missing data are handled in instructional technology research, articles published in "Educational Media International,""Educational Technology Research and Development," and "Performance Improvement Quarterly" for the last 5 years are reviewed. A total of 84 quantitative research articles were identified in the 3 journals. About 42% of the reviewed studies had incomplete data sets, and in most of them, information about data completeness was clearly presented through comparisons of usable data points with the intended sample size. Overall, it was found that the awareness of missing data issues was low among the researchers in the field of instructional technology. Findings are discussed in terms of missing data mechanisms, and recommendations are presented. An appendix shows missing data methods in the three journals in table form. (Contains 19 references.)
