Hipotesi is a very great usefulness in Scientific Investigation.
Hypothesis allows us to connect theory with Observation, and vice versa Observations with theory.
TYPE OF RESEARCH VARIABLES
Its value is seen from the scale variable :
- Continuous variables are variables that have a regular set of values within a certain range. High-being for example, one up to 7.
- Categorical variables are variables that have values based on certain categories (nominal scale) Example: Attitude: Good-bad, Judging from the treatment.
- Active Vaariabel the manipulated variables for experimental research.
- Variable attributes are variables that can not be manipulated for the purposes of research, eg, intelligence, attitude, gender and so on. Variable views of its function:
- The independent variable
- The dependent variable.
- Moderating Variables
- Intervening variable.
Operational Definitions
- Operational definition is the determination to construct a variable that can be measured.
- Describe specific ways that are used to construct operational making it possible for other researchers to replicate measurements in the same way or develop a better measurement cosntruct.
Theory and Research
- The study is basically an operationalization of the scientific method, the method used to acquire scientific knowledge.
- The theory is part of science that explain natural phenomena. Because of the theoretical part of science has closely interwoven with the study.
- Research is a systematic process for developing the theory.
The Position and Role of Theory
- For quantitative research, the theory underlying the Environment for the formulation, development of hypotheses, testing data and making conclusions, so the results could support or rejection of the theory.,
- In qualitative research, the theory is the culmination of qualitative research is compiled through a process of data collection, categorization of data and development of the pattern or arrangement of the theory.
Proposition and Hypotheses
- The proposition is an expression or statement to be believed, denied or verifiable, megenai concept or construct that explain or predict phenomena.
- The proposition is formulated with a view to test the hypothesis empirically known.
- Hypothesis states that alleged relationship between two or more variables in the formulation of propositions that can be tested empirically.
- Hypotheses can be derived from the study of theory and previous research / empirical.
Function Hypothesis
- Describe the research problem and its solution.
- Declare variables that need to be tested empirically
- Used as a guide for selecting the methods of testing data.
- Become a basis for conclusions.Source: Hypothesis
