Definitions of Hypothesis

definitions of hypothesis

Hypothesis word is taken from the Greek words ‘Hypo’ and ‘Tithenas’. ‘Hypo’ means under and ‘Tithenas’ means to place. In easy words we can understand that hypothesis is an intelligent prediction through which the researcher finds the relationship between two or more variables and the conclusions of the research are revealed.

The hypothesis plays one of the most important role in the whole research process done by the researcher as the hypothesis suggests which sort of research method and analysis technique are the best to choose for the particular research problem.

Example of Hypothesis: “There is no significant difference between the intelligence level of boys and girls of arts and science streams.”  (It is an example of Null Hypothesis and here the researcher wants to relationship between the intelligence level of boys and girls of arts and science streams.)

Let’s explore few major definitions of hypothesis.

Definitions of Hypothesis

“A hypothesis is a tentative generalization, the validity of which remains to be tested. In this most elementary stage, the hypothesis may be very hunch, guess, imagination data, which becomes the basis for action or investigation.”

—— George A Luniberg

“A hypothesis is written in such a way that it can be proven or disproven by valid and reliable data – in order to obtain these data that we perform our study.”

 —— Jr. Richard Grinnell

“A hypothesis is a statement capable of being tested and thereby verified or rejected.”

—— Rummel and Balline

“A hypothesis is a proposition, condition or principle which is assumed, perhaps without belief, in order to draw out its logical consequences and by this method to test its accord with facts which are known or may be determined.”

—— Webster Dictionary

“Hypothesis is a proposition which can be put to test, to determine validity.”

—— Goode and Hatt

 “A hypothesis is an attempt at explanation of a provisional supposition made in order to explain scientifically some facts or phenomenon.”

—— Coffey

“A tentative statement about something, the validity of which is usually unknown.”
