| dc.description.abstract | According to inferential and descriptive statistics, sample size of any population is a subset or a smaller unit of the main population on which a research is to be carried out. For the outcome of any research about a population to be generalized, the sample size has to be able to explain the characteristics of the main population under study. Sample size calculation, when done manually can be achieved but it can be nearly impossible when confronted with large population.
Furthermore, the Ever-increasing demand for research has created need for an efficient method of determining sample size needed to be representative of a given population. Perhaps the most frequently asked question concerning sampling is, "What size sample do I need?" The answer to this question is influenced by a number of factors, including the purpose of the study, population size, the risk of selecting a "bad" sample, and the allowable sampling error.
In order to enhance the precision of our survey or research, this program has been developed to assist researchers at all level in determining the right sample size to be used when studying any population. | en_US |
