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

The authors present the “Buyer Utility Map“ which is supposed to enable managers to determine the different utility from existing products. I as a manager can understand the levers and stages they cover to introduce a new product to the market‚ but however‚ I think the approach is highly theoretical and very narrowly minded. Basically‚ a potential buyer would first think of the

HYPOTHESIS TESTING WHAT IS THIS HYPOTHESIS???? • In simple words it means a mere assumption or supposition to be proved of disproved. • But‚ for a researcher it is a formal question that he intends to resolve. • Example: I assume that 1) under stress and anxiety a person goes into depression. 2) It leads to aggressive behaviour. Eg. : Students who get better counselling in a university will show a greater increase in creativity than students who were not counselled. • So‚ the hypothesis
