Alternative hypothesis H1
In practice, a researcher never works on the null hypothesis alone.
An alternative hypothesis is pursued in Colzato, Wouwe & Hommel's recently accepted manuscript at Neuropsychologia. According to this framework, visuomotor binding is accomplished by the dopaminergic system.
An obvious alternative hypothesis, illustrated in Figure2, is that the brain (like everything else we perceive) is a creation within one's world of experience, as represented by the large oval, from an underlying reality (the lower rectangle).
A statement of the alternative hypothesis, e.g., two population means are not equal.
Test Statistic:
The test statistic is based on the specific hypothesis test.
The second and alternative hypothesis (H1) is that the diameters of the piston rings delivered to us deviate from specifications by more than a certain amount.
In traditional statistical hypothesis testing, the tester starts with a null hypothesis and an alternative hypothesis, performs an experiment, and then decides whether to reject the null hypothesis in favour of the alternative.
