What are different types of hypothesis

 TYPES OF HYPOTHESIS • Simple • Complex • Empirical • Null • Alternative • Logical • statistical

SIMPLE HYPOTHESIS • Simple hypothesis is that one in which there exits relationship between two variables one is called independent variable or cause and the other is dependent variable or effect. • Ex. 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. • In this type dependent and independent variables are more than two • Ex. Smoking and other drugs leads to cancer, tension, chest infections etc. • The higher ration of unemployment poverty illiteracy leads to crimes like dacoit etc.

EMPIRICAL HYPOTHESIS • Empirical which means it is based on evidence. • In scientific method the word "empirical" refers to the use of working hypothesis that can be tested using observation and experiment. • Empirical data is produced by experiment and observation.

QUESTION FORM OF HYPOTHESIS • It Is the simplest form of empirical hypothesis. • In simple case of investigation and research are adequately implemented by resuming a question. • Ex. how is the ability of 9th class students in learning moral values?

NULL HYPOTHESIS • Null the hypothesis that there is no significant difference between specified populations, any observed difference being due to sampling or experimental error. • It is denoted by H0

ALTERNATE HYPOTHESIS • The alternative hypothesis, denoted by H1 or Ha, • Is the hypothesis that sample observations are influenced by some non-random cause.

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..
