This chapter introduces the second form of inference: null hypothesis significance tests (NHST), or... 5/12/2007 · The alternative hypothesis (or maintained hypothesis or research hypothesis) and the null hypothesis are the two rival hypotheses whose likelihoods are compared by a statistical hypothesis test. Usually the alternative hypothesis is the possibility that an observed effect is genuine and the null hypothesis is the rival possibility that it has resulted from random chance.

**How to choose null hypothesis vs alternative hypothesis**

The Null and Alternative Hypothesis. We usually set the hypothesis that one wants to conclude as the alternative hypothesis, also called the research hypothesis. There are three types of alternative hypotheses: 1. The population parameter is not equal to a certain value. Referred to as a "two-sided test". 2. The population parameter is less than a certain value. Referred to as a "left-tailed... The null hypothesis for this one-tailed test is that π ≤ 0.5, where π is the probability of being correct on any given trial. If this null hypothesis is rejected, then the alternative hypothesis that π > 0.5 is accepted. If π is greater than 0.5, then Mr. Bond is better than chance on this task.

- 5/12/2007 · The alternative hypothesis (or maintained hypothesis or research hypothesis) and the null hypothesis are the two rival hypotheses whose likelihoods are compared by a statistical hypothesis test.

- The difference between the null hypothesis and the alternative hypothesis are on the sense of the tests. In statistical inference, the null hypothesis should be in a positive … sense such in a sense, you are testing a hypothesis you are probably sure of.
- Null hypothesis: There is no clear winning opinion on this issue; the proportions who would answer yes or no are each 0.50. Alternative hypothesis: Fewer than 0.50, or 50%, of the population
