# How to differentiate null and alternative hypothesis

With hypothesis testing, the null hypothesis states that there is no difference or association between variables of interest. In the classical sense of hypothesis testing, researchers are not trying to prove that their research hypothesis true, they are trying to prove if the null hypothesis is true or untrue.
вЂў The mathematical formulation of a null hypothesis is an equal sign but for an alternative hypothesis is not equal to sign.
A statistical hypothesis used in hypothesis testing, which states that there is a significant difference between the set of variables. It is often referred to as the hypothesis other than the null hypothesis, often denoted byВ H 1 (H-one). It is what the researcher seeks to prove in an indirect way, by using the test. It refers to a certain value of sample statistic, e.g., xВЇ, s, p
вЂў In null hypothesis, the observations are the outcome of chance whereas, in the case of the alternative hypothesis, the observations are an outcome of real effect.

17.05.2011 · The alternative hypothesis is that there is a difference. For example, a null hypothesis could be that participation in a tutoring program for reading makes no difference in the results of a reading comprehension test The alternative hypothesis would be that participation in the program does make a significant difference when it вЂ¦

Null hypothesis vs. alternative hypothesis Suppose that we have data y =( y 1 ,···,y n ) and the data is generated by the true probability distribution P Оё 0 , from a family of probability distribution P Оё indexed by Оё в€€ О .
The null hypothesis (H 0) is a hypothesis which the researcher tries to disprove, reject or nullify. The 'null' often refers to the common view of something, while the alternative hypothesis is what the researcher really thinks is the cause of a phenomenon.
The choice of a "null" hypothesis and an "alternative" hypothesis depends on the decision/argument you want to make. When trying to remember the difference between a null hypothesis and an alternative hypothesis--at least in the context of null hypothesis significance testing--imagine yourself trying to make the following вЂ¦
