CHAPTER V
NEED FOR THEORETICAL FRAMEWORK
Theoretical framework: a conceptual model of how one theorizes or makes logical sense of the relationships among the several factors that have been identified as important to the problem.
➢ This theory flows logically from documentation of previous research in the problem area.
➢ Integrating one’s logical beliefs with published research, taking into consideration the boundaries and constraints governing the situation, is pivotal in developing a scientific basis for investigating the research problem.
➢ Theoretical framework: discusses the interrelationships among the variables that are deemed to be integral to the dynamics of the situation being investigated.
➢ From the theoretical framework, then, testable hypotheses can be developed to examine whether the theory formulated is valid or not.
➢ The entire research rests on the basis of the theoretical framework.
VARIABLES:
Variable: anything that can take on differing or varying values.
4 main types of variables:
1. Dependent variable (also known as the criterion variable)
2. Independent variable (also known as predictor variable)
3. Moderating variable
4. Intervening variable
Dependent variable:
• Variable of primary interest to the researcher
• The researcher’s goal is to understand and describe the dependent variable, or to explain its variability, or predict it
• The main variable that lends itself for investigation as a viable factor
• It is possible to have more than one dependent variable in a study
Independent variable:
• One that influences the dependent variable in either a positive or negative way
• When the independent variable is present, the dependent variable is also present
• With each unit of increase in the independent variable, there is an increase or decrease in the dependent variable also
• Variance in the dependent variable is accounted for by the independent variable
Moderating variable:
• One that has a strong...
