A CRITICAL ANALYSIS OF THE POTENCY OF HYPOTHESES: ASSESSING THE ROLES AND WEAKNESSES OF THE NULL AND ALTERNATIVE HYPOTHESES AS PERCEIVED BY POST GRADUATE RESEARCH STUDENTS IN AKWA IBOM STATE TERTIARY INSTITUTIONS
This study analysed the potency of null and alternative hypotheses, assessing their roles and weaknesses of the null and alternative hypotheses as perceived by post graduate research students in Akwa Ibom State tertiary institutions. Descriptive survey design was adopted to carry out this research. The targeted population for the study comprised all post graduate research
students made up of Master degree and Ph.D research students in tertiary institutions in Akwa Ibom State. Simple random sampling technique was used to select 80 post graduate research students each from University of Uyo and Akwa Ibom State University and this gave a sample size of 160 respondents which was used for this research. The instrument used for data collection
was a structured questionnaire titled “Hypothesis Potency Questionnaire (HPQ)”. Face and content validation of the instrument was carried out by an expert in test, measurement, and evaluation in order to ensure that the instrument has the accuracy, appropriateness, and completeness for the study under consideration. The reliability coefficient obtained was 0.89, and this was high enough to justify the use of the instrument. The researcher subjected the data generated for this study to appropriate statistical technique such as descriptive statistics. The result of the data analysis concluded that “Direction and Focus” among many others was the most prominent potency of hypothesis in research. It also showed that “Preventing Researcher Bias” among others was the most prominent role of null hypothesis in research. One of the recommendations made was that researchers should complement or replace traditional null hypothesis significance testing (NHST) with Bayesian inference and estimation-based models.
