Study Notes
Variables
- Active variables: Don't preexist, created by the researcher
- Attribute variables: Often inherent, such as blood type
- Extraneous variables: Can confound the relationship between dependent and independent variables, need to be controlled
- Demographic variables: Attributes of the subject, collected to describe the sample, such as age
Dependent and Independent Variables
- Independent variable: Presumed cause, controlled, and manipulated
- Dependent variable: Presumed effect, measured, and changed
Characteristics of Variables
- Dependent variable: Measured, not manipulated, and varies at an unknown rate
- Independent variable: Controlled, manipulated, and intentionally changed
Types of Influences
- Confounding variable: Exerts influence on the dependent variable, but is not an independent variable
- Influencing variable: Exerts influence on the dependent variable, not an independent variable
Research Concepts
- Concept: A linguistic label assigned to objects or events through observation
- Construct: A concept deliberately invented by a researcher for a specific purpose
- Theory: Relationships among phenomena
Research Methods
- Critical reading: A skill that involves preliminary, comprehensive, analysis, and synthesis steps
- Critical appraisal: Evaluates the strengths and weaknesses of research
Abstract
- A short, comprehensive summary of a study at the beginning of an article
- Typically 50-250 words, includes background, purpose, design, methods, results, conclusions, recommendations, and key words
