Definition of Research Hypothesis | Meaning of Hypothesis in Research

In this article, I will discuss the complete hypothesis definitions and hypothesis characteristics. In scientific work any statement, proposition, or assumption that serves as a tentative explanation of certain facts. Here we will also discus research hypothesis.

 

A hypothesis is always presented so as to be amenable to empirical test and then either supported or rejected by the evidence.

Definitions of Hypothesis

According to McGuigan hypothesis is a testable statement of a potential relationship between two or more variables.

Hilway said that estimate to do a work is called a hypothesis.

A strategy adopted in order to solve some problems is called a hypothesis.

Types of Hypothesis

There are major two types of hypotheses testing.

1. Scientific Hypothesis or Void Hypothesis

Scientific hypothesis represents the predicted relationship among the variables being investigated.

2. Null Hypothesis

The null hypothesis represents a statement of no relationship between the variables being investigated.

Examples of Hypothesis

Someone wants to explore the nature of the memory deficits that occur through the influence of alcohol. 

In a scientific hypothesis, the relationship between alcohol and memory is a factual event. When intoxicated individuals would fail to recall meaningful context during the taking of alcohol.

But in some circumstances, the null hypothesis insist that it makes no difference at all. The meaningful context recall even who have approached alcohol or who did not do so

Null hypothesis rejects that there is a relationship between alcohol and memory recall.

Characteristics of Hypothesis

The characteristics of a good hypothesis are as under:

1. The hypothesis must be testable.
2. It should be in general harmony with other hypotheses in the field of investigation.
3. Hypothesis should be parsimonious.
4. Hypothesis should answer (be relevant to) the particular problem addressed, and some other one.
5. A hypothesis should have logical simplicity.
6. Hypothesis should be expressed in quantified form.
7. Hypothesis should have a large number of consequences and should be general in scope.
8. Hypotheses are never absolutely true or false, but have a determinable degree of probability.
9. Hypotheses are basically stated as general implications.
