scientific research hypotheses Formulate

      Hypothesis is considered as the third step in writing and preparation of scientific research, it is built according to research problem that revolves around it, it may be a single hypothesis of the overall framework, or a set of sub-assumptions which emanating from it.

Hypotheses definition:

Hypotheses can defined as:

1. A broad field to solve a problem that researcher trying to  solve.
2. A set of simultaneous analyzes imposed by the researcher according to his decisions and  experience depending on in a specific topic to solve the problem, beside formulate all the hypotheses  in a way that make the reader  feels deep related  with the problem.

The Importance of Research Hypotheses:

1. Explain and define search field boundaries.
2. gathering Research ideas around a loop or a central point which information centering on.

Search hypothesis properties:

1. search hypotheses focus on  research sample community  and determine the relationship between them and the variables by subtracting a set of multiple points.
2. Hypothesis leads to negative and positive aspects, not restricted on one side.
3. The hypothesis is not a theorem but it is demonstrated by  logic analysis and reasons.
4. Inquire about validity and trustiness of  hypothesis.
5. One hypothesis may holds many questions and concepts in it.

Research hypothesis Components:

• Variables: which is Two types:

1. Independent variable: A variable whose behavior and results are searched for.
2. The dependent variable: which is studied and analyzed in order to know its relationship of the independent variable.

• Relationships between variables.
• Statistical Society: A sample or research community.

Methods of hypothesis formulate:

1. Differential formula (comparison): This formula is created as a comparison between two cases.
2. Embedding formula: as a conditional statement.
3. Report Formula: It is a notification of order or something.
4. The  invitation formula: In these hypotheses claims  search further inquiries, research and investigation.

How to test hypothesis validity:

• Determine the relationship of the hypothesis validity.
• Develop a model for the hypothesis, whether numeric or alternative.
• Collecting data and information about the problem.
• Following a method of inductive statistics in order to know  probability of the hypothesis.

Things should follow when formulating a scientific hypothesis:

1. hypothesis should covers all aspects of the research according to its topics.
2. The hypothesis is formulated by negation or proof.
3. short and easy to understand.

Criteria for assessment of hypotheses:

1. searchable and tested.
2. hypothesis must focus on relations between variables.
3. include documentation of previous studies, rules and theories.
4. limited and not broad in scope.

Sources of hypothesis formulation:

• Observation and personal experiences: the researcher's reliance on the observations they make in his imagination.
• Taking advantage of scientific theories: The researcher examines the theories of the research title.
• Logic: the arbitration of reason and logic.
• Intuition and guessing: The hypothesis that built on the intuition of researcher suffers from linking them to the general concept of the subject and framework of research.

Features of hypothesis formulation:

• To be consistent with scientific facts and to keep away from imagination and counterfeiting.
• clear, explained and easy to understand.
• To provide a solution to a specific problem or an explanation of a specific phenomenon.
• Choose a precise method to formulate and make it testable and verifiable.
• To be far from the personal impression of the researcher.
• focusing on one main hypothesis and a set of sub-hypotheses.
• related to the title, location and problem of the research.
