Application of appropriate research methods has assumed an important role in knowledge accumulation endeavors in the scientific research community. The current study reported here summarizes how we used the empirical methods in IS research, what we need to improve in using empirical study as research methodology through the set of comprehensive research guideline. From the survey and review of seminal and classical research guidelines, we developed our own 28 checklist for research design, statistical analysis, and conclusion, which can be commonly applied to all articles that employ inferential statistical methods in IS research. Then, we critically evaluated the usage of empirical research methods in major IS journals by using the checklist, with the goal of improving the quality of academic papers. In this study, we scrutinized four major IS journals which published empirical papers from 1991 to 2000: MIS Quarterly, Journal of MIS, Information Systems Research, and Decision Sciences. As a result of intensive evaluation work, we could highlight many areas that are lagging and call for greater attention with regard to the proper usage of empirical study in IS research. The research findings in this study can be referred as checklist and guideline when IS researcher applies the empirical method.

Purpose - The paper aims at testing the moderating effect of individualism dimension of culture on consumer behavioural intention about bank services in Nigeria. Research design, data, and methodology - A survey was conducted with a sample of five hundred and fifty five bank customers drawn from various retails banks. Using Statistical Package for Social Sciences and Analysis of Moment Structure, combinations of descriptive and inferential statistics were performed. Invariance test and multiple-group analysis were conducted in order to assess the moderating effect. The invariance test was necessary to confirm the equivalence of constructs so that any difference detected thereafter could be related to moderating effect. Results - The results show that individualism has a significant moderating effect on the relationship between technical quality, perceived value and corporate image on the one hand, and behavioural intention on the other. However, individualism does not moderate the association between functional quality and behavioral intention. Conclusions - It is recommended that the bank policy makers should take necessary step to enhance the customer perception of technical quality, perceived value and corporate image with respect the retail bank services.
