Why We Study Research?
There are 5 general reasons of studying research. 1. Description 2. Explanation 3. Forecasting 4. Modeling 5. Evaluation
These are not completely independent from each other, they are almost interdependent. The two most frequent objectives are description and explanation.
Description: Research is studied to describe the subjects as (gender, race, age, income, work status, political affiliation, etc.).This is just an exploratory phase that is undertaken using graphical representations and statistical measures that are not inferential.
Explanation: Here we can uncover cause and effect relationships that involve precise hypotheses to be confronted that deals with inferences.
Forecasting: This phase deals with the predictions about the conclusions of the research to be conducted, based on the past descriptive research and trends.
Modeling: Here we can present our study in a structured way by building some mathematical models which are designed to improve understanding of research.
Evaluation: By studying research we can evaluate the effectiveness of a certain research programs in various sectors.
What Is a Theory?
A theory is a based upon a hypothesis and backed by evidence. A theory presents a concept or idea that is testable. In social sciences, theories are used to provide a model for understanding human thoughts, emotions and behaviors. A social sciences theory has two key components: (1) It describes a behavior (2) It makes predictions about future behaviors.
The Purpose of Theory
(1)Structured Way of Exploration (2) Interpretation of Certain Experiences (3) The Catalog of Experiences (4) Enthusiasm for Exploration (5) To Know the Reality

Levels of Theory
Micro level Theory: Micro-level theories are concerned with individuals and their interactions. For example the relationship between adult
