Study Notes
Research Designs
- Experimental research design allows for conclusions about cause and effect relationships among variables.
Correlations
- A negative correlation indicates that one variable decreases as the other increases.
- Correlation signifies a relationship between two or more variables, which may not imply causation.
Longitudinal Studies
- Longitudinal research involves studying the same group of participants over an extended time period to observe changes and developments.
Illusory Correlation
- The belief that unusual behavior, such as strange actions, is linked to full moons exemplifies an illusory correlation, where perceived relationships are not statistically significant.
Case Studies
- Krista and Tatiana Hogan, conjoined twins connected at the head, are subjects of a case study, allowing for an in-depth examination of unique circumstances.
Theories
- A theory represents a well-developed set of ideas aiming to explain observed phenomena through coherent and interrelated concepts.
Naturalistic Observation
- Research employing experimental confederates at speed dating events to observe dater behaviors is an example of naturalistic observation, focusing on real-world settings without manipulation.
Variables in Research
- In a study, the independent variable is the learning strategy employed, while the dependent variable is word retention, reflecting the outcome of the learning strategy's effect.
Attrition
- Attrition refers to the reduction in the number of research participants over time, often due to dropouts, which can impact the validity of study results.
