Below are some of the important types of hypothesis

- Simple Hypothesis
- Complex Hypothesis
- Empirical Hypothesis
- Null Hypothesis
- Alternative Hypothesis
- Logical Hypothesis
- Statistical Hypothesis

##
**Simple Hypothesis**

Simple hypothesis is that one in which there exists relationship between two variables one is called independent variable or cause and other is dependent variable or effect. For example

- Smoking leads to Cancer
- The higher ratio of unemployment leads to crimes.

##
**Complex Hypothesis**

Complex hypothesis is that one in which as relationship among variables exists. I recommend you should read **characteristics of a good research hypothesis**. In this type dependent as well as independent variables are more than two. For example

- Smoking and other drugs leads to cancer, tension chest infections etc.
- The higher ration of unemployment poverty, illiteracy leads to crimes like dacoit, Robbery, Rape, prostitution & killing etc.

##
**Empirical Hypothesis**

Working hypothesis is that one which is applied to a field. During the formulation it is an assumption only but when it is pat to a test become an empirical or working hypothesis.** **

##
**Null Hypothesis**

Null hypothesis is contrary to the positive statement of a working hypothesis. According to null hypothesis there is no relationship between dependent and independent variable. It is denoted by ‘HO”.

##
**Alternative Hypothesis**

Firstly many hypotheses are selected then among them select one which is more workable and most efficient. That hypothesis is introduced latter on due to changes in the old formulated hypothesis. It is denote by “HI”.

##
**Logical Hypothesis**

It is that type in which hypothesis is verified logically. J.S. Mill has given four cannons of these hypothesis e.g. agreement, disagreement, difference and residue.

##
**Statistical Hypothesis**

A hypothesis which can be verified statistically called statistical hypothesis. The statement would be logical or illogical but if statistic verifies it, it will be statistical hypothesis.
