The Reversal Techniques for Finding out the Genuine Level of Confidence or Error in Sample Size Determination Used in the Study of Population Proportion for the Quantitative Research Design

Abstract

In the Quantitative Research Design, the study of Population Proportion () is one type of the study that the sample size was determined in advance by the use of the formulae or the sample size table involved under the specific level of confidence and the error needed.  However, the real number of samples that be used could be different from that was determined earlier by any reason; so those specific level of confidence and/or the error be changed automatically but many researchers did not report that changes of the level of confidence and/or the error in their research report. This article should try to propose the reversal techniques formulae that could be used to identify the new Level of Confidence and/or the Error occurred which it could be reported by the researcher to let the readers recognize and evaluate the research result correctly.
