STEPS IN SCIENTIFIC RESEARCH: ARCHITECTURAL RESEARCH: AN INTERDISCIPLINARY REALITY Hypothesis is a tentative explanation that accounts for a set of facts and can be tested by further investigation. Generation of Research Hypothesis Research usually starts with a problem. Questions‚ objectives and Hypotheses provide a specific restatement and clarification of the problem statement/research question. In qualitative research‚ the research question may assume two forms: The grand tour

RESEARCH METHODOLOGY LESSON 20: PRINCIPLE OF HYPOTHESIS TESTING So far we have talked about estimating a confidence interval along with the probability (the confidence level) that the true population statistic lies within this interval under repeated sampling. We now examine the principles of statistical inference to hypotheses testing. By the end of this chapter you should be able to • Understand what is hypothesis testing • Examine issues relating to the determination of level of How is this
