    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

    A hypothesis is a speculation or theory based off of insufficient evidence which can later be tested to be proven true or false. An example of a hypothesis would be testing if one type of drug performed better to prevent seizures than the other. A Null hypothesis is a hypothesis that says there is no statistical significance between variables in a given hypothesis. An example of a null hypothesis would be there is no statistical relationship between which type of drug used and the amount of prevented
