DEFNITIONS: • Hypothesis is considered as an intelligent guess or prediction, that gives directional to the researcher to answer the research question. • Hypothesis or Hypotheses are defined as the formal statement of the tentative or expected prediction or explanation of the relationship between two or more variables in a specified population

●A hypothesis is a formal tentative statement of the expected relationship between two or more variables under study. • • A hypothesis helps to translate the research problem and objective into a clear explanation or prediction of the expected results or outcomes of the study.

●CONTRIBUTIONS OF HYPOTHESIS It provides clarity to the research problem and research objectives. • It describes, explains or predicts the expected results or outcome of the research. • It indicates the type of research design. • It directs the research study process. It identifies the population of the research study that is to be investigated or examined. It facilitates data collection, data analysis and data interpretation

● FUNCTIONS • It enables an investigator to start his research work. • It may lead to formulations of another hypothesis. • It leads to interpret results drawing conclusions related to original purpose.

●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.

Answer:

A hypothesis is assumptions and ideas proposed for discussion purposes so that they can be tested to see if they are true.

Explanation:

  • A hypothesis is an approximate statement based on a set of facts that can be tested by a particular further investigation. There are basically two types, the null hypothesis and the alternative hypothesis.
  • The null hypothesis is a typical statistical theory that suggests that there is no statistical relationship and significance for a particular set of observation variables between two sets of observational data and the measured phenomenon.
  • The alternative hypothesis indicates that the population parameters are less than, greater than, or different from the hypothesis values ​​of the null hypothesis. An alternative hypothesis is one that you believe to be true or want to be true.
