Study Notes
Non-experimental Design
- Non-experimental design involves natural observation of phenomena, without manipulation of variables or controlled settings.
- Also referred to as Descriptive Research Design, the primary goal is to observe and document situations as they occur.
- Serves as a foundational approach for hypothesis generation and analysis.
Types of Descriptive Design
-
Survey
- Gathers information from specific groups by selecting and analyzing samples from a broader population.
-
Correlational Research
- Studies aim to identify relationships between two or more variables without manipulation by the researcher.
- Encompasses three main types:
-
Bivariate Correlational Studies
- Collects scores from two variables per subject to calculate a correlation coefficient, indicating a relationship.
-
Prediction Studies
- Utilizes correlation coefficients to assess how one variable predicts another (predictor variable vs. criterion variable).
-
Multiple Regression Prediction Studies
- Involves multiple variables contributing to an overall prediction through an equation that combines their predictive abilities.
-
Bivariate Correlational Studies
-
Ex-post Facto or Causal-comparative
- Analyzes conclusions based on previously observed phenomena, comparing them to dependent variables.
- Focuses on understanding the reasons and mechanisms behind occurrences that have already taken place.
