Influencing factors and calculation strategies for survey research

selected? Unfortunately, the answer to these questions are not as easy as the researcher desires. There are factors which influence determining sample size and others influence determining sampling design. The researcher needs to know these factors and their effect beforehand to succeed in determining the adequate sample size. This paper attempts to highlight the factors relevant to determining the minimum sample size needed for descriptive studies and introduce some useful strategies that can be employed for the purpose of sample size determination. Factors influencing determining sample size. Determining the adequate sample size is the most important design decision that faces the researcher.2 The reason for this is that using too low sample size, the research will lack the precision to provide reliable answers to the questions that are under investigation. Moreover, using too large sample size, time, and resources will be wasted often for minimal gain. As stated previously, there are factors playing a vital role in determining the sample size. Knowing these factors and their effect helps the researcher to determine the sample Sample size determination
