# Types of Hypothesis

Alternative Hypothesis (Denoted by "H1") The alternative hypothesis is what we are attempting to demonstrate in an indirect way by the use of our hypothesis test. If the null hypothesis is rejected, then we accept the alternative hypothesis. If the null hypothesis is not rejected, then we do not accept the alternative hypothesis.

Clarity A hypothesis brings clarity to a research hence making it easier to understand. Clarity is very important especially there should have to be clarity in the research ...

Closest to Observable Things Of a usuable hypothesis it is expected that it should be closest to the things observable. In case that is not so it will not be possible to test its accord with empirical facts. A good hypothesis should be formulated in such a manner that some deductions can be derived from it.

Complex Hypothesis hypothesis alternative hypothesis the hypothesis that is formulated as an opposite to the null hypothesis in a statistical test. complex hypothesis a prediction of the relationship between two or more independent variables and two or more dependent variables.

Null Hypothesis (Denoted by "HO") This hypothesis is denoted by H 0. The null hypothesis is what we attempt to find evidence against in our hypothesis test. We hope to obtain a small enough p-value that it is lower than our level of significance alpha and we are justified in rejecting the null hypothesis. If our p-value is greater than alpha, then we fail to reject the null hypothesis.

Power of Prediction Hypothesis vs. Prediction. Is there a difference? If so, what is it? “We routinely use the term ‘hypothesis’ when we mean ‘prediction.’ This unacceptable substitution dilutes the power of the scientific method to the extent that invoking the ‘scientific method’ has become largely meaningless” Guy McPherson, American Biology ...

Relevant to Problem The precursor to a hypothesis is a research problem, usually framed as a question. It might ask what, or why, something is happening. For example, to use a topical subject, we might wonder why the stocks of cod in the North Atlantic are declining.

Simple Hypothesis A hypothesis which is not simple (i.e. in which not all of the parameters are specified) is called a composite hypothesis. For instance, if we hypothesize that (and ) or and , the hypothesis becomes a composite hypothesis because we cannot know the exact distribution of the population in either case.

Simple Hypothesis A simple hypothesis is one in which all parameters of the distribution are specified. For example, the heights of college students are normally distributed with , and the hypothesis that its mean is, say, ; that is, . So we have stated a simple hypothesis, as the mean and variance together specify a normal distribution completely.

Simplicity Ernst Gombrich proposed the simplicity hypothesis as an explanation of how perception operates. We scan a territory and selectively attend to just a few objects because, we recognized a pattern of redundancies. Selective attention gives us all the information we need to make our hypothesis of what is present.

Statistical Hypothesis A statistical hypothesis is an assumption about a population parameter. This assumption may or may not be true. Hypothesis testing refers to the formal procedures used by statisticians to accept or reject statistical hypotheses.

Testability A testable hypothesis is a form of a hypothesis that can either be supported or else falsified from data or experience. It's the type of hypothesis you want to state in order to conceive and perform an experiment using the scientific method.
