"The Software nMaster 2.0 has advantage over software that incorporates sample size calculation(STATA, EpiInfo, nQuery, etc.), in terms of contents, each of use and the cost. No other software incorporates all the situations that have been incorporated in the nMaster 2.0. The target audience for nMaster 2.0 is anyone (from residents, Ph.D. students to independent researcher) who is involved in doing quantitive research or consumer of quantitative research."

“This is one of the excellent package which is available for calculation of sample size. My faculty colleagues, masters and research student equally enjoy using this package”

“Good Research Method is Good Ethics”. There is a growing recognition on the importance of sample size calculation and power analysis in research. When planning a study design, it is very imperative to consider how many participants are needed, therefore, sample size must be premeditated carefully to ensure that the research time, patient effort and support costs invested are not wasted. There are many standard statistical software and stand alone packages available in public domain (internet) for performing sample size/power calculations. However, validity of those software are not authenticated and documented. On the other hand, the commercial software are unaffordable by the researchers from developing countries. Also, the software packages which are available do not provide the details of the literature behind the technique. Thus, there is a great urge for developing a holistic tool, which will provide the situation where that particular formula needs to be applied, assumptions involved, the relevant bibliography and then the details of the formula. This paved a way for the development of ‘nMaster 2.0’.
