Study Notes
Characteristics of a Hypothesis
- A hypothesis can be tested and is verifiable or falsifiable
- A hypothesis is logical and directly related to the research problem
- A hypothesis is neither too specific nor too general and provides a prediction of consequences
- A hypothesis sets the limits of the study and is considered valuable even if proven false
Purpose and Importance of a Hypothesis
- A hypothesis provides a tentative explanation of phenomena and facilitates knowledge extension
- A hypothesis offers a testable relational statement, direction, and a framework for reporting conclusions
- A hypothesis potentially serves as a working instrument of theory
Types of Hypotheses
- Null Hypothesis (H0): represents a theory that has been put forward but has not been proven
- Alternative Hypothesis (Ha): is a statement of what a hypothesis test is set up to establish and is often the actual desired answer of the researcher
Experimental Research
- Experimental research uses the scientific method to test cause-and-effect relationships under controlled conditions
- An independent variable is manipulated to determine its effects on the dependent variable
Importance of Quantitative Research
- In ABM, quantitative research helps with designing new products, ensuring product distribution, and determining store opening times
- In STEM, quantitative research helps medical practitioners understand disease trends, risks, and outcomes of health interventions
- In HUMSS, quantitative research addresses social problems like stress, work ethics, and child labor
- In SPORTS, quantitative research is used in various applications such as sports analytics
Kinds of Quantitative Research
- Descriptive Research: describes the nature, characteristics, and components of a population or phenomenon
- Correlational Research: systematically studies relationships among variables and predicts performance in tests
- Evaluation Research: evaluates the effects and outcomes of practices, policies, and programs
- Survey Research: gathers information from a population through various methods
- Causal Comparative Research: uses past observations and manifestations to understand why and how a phenomenon occurs
