Basic concepts are examined before utilising the statistical software package GPower to illustrate the use of alpha level, beta level and effect size in sample size calculation. To enable researchers and research ethics committee members with non-statistical backgrounds to use freely available statistical software to explore and address issues relating to sample size, effect size and power. Sample size estimation is now a major, but often misunderstood concern for researchers, academic supervisors and members of research ethics committees.
