Use of Statistics are involved in various stages of research such as research design at the beginning stage, determination of adequate sample size, random group allocation, data collection/management/analysis, and writing and interpretation of statistical results. As access to user -friendly statistical packages gets easier, it is more likely that wrong analyses are made due to mistakes by lack of fundamental knowledge of Statistics, which might lead to wrong study conclusions. In this paper, correct use of Statistics will be presented to prevent or minimize ethical or scientific problems.
