Evaluating Sources
Importance of Evaluation
- The world has vast information, but not all is valid or accurate.
- Evaluating sources requires detective work to determine where to look and what to accept.
Definitions
- Validity: Extent to which data measures intended outcomes accurately.
- Reliability: Extent to which we can depend on the source and its data.
Characteristics of Validity
- Sources may have high reliability but low validity (e.g., outdated data).
- Validity considers accuracy and bias.
- Factors affecting validity:
- Currency: Timing of data publication.
- Relevance: Applicability of information to the context.
- Representativeness: Inclusion of diverse variables affecting response.
- Data Collection: Reliability of data collection methods.
- Sample Size: Adequacy of sample size for generalizability.
- Bias: Cultural, social, or political influences affecting data presentation.
Characteristics of Reliability
- Author/Authority: Expertise and qualifications of the author.
- Professional Standards: Adherence to professional standards (e.g., academic publishing).
- Publisher: Reputation and editing standards of the publisher.
- Organization/Institution: Credibility of the data source (e.g., respected organizations).
- Research Method: Suitability of the method for generating necessary data.
Evaluating Sources
- Print Sources: Rigorously reviewed and fact-checked ensuring high validity.
- Internet Sources: Often lack review process, making them more variable in quality; possibly misleading or outdated.
Application Activity
- Example: Adolescent Psychology section highlighting negative self-perception among teens due to societal pressures regarding body image.
Model Evaluation of a Secondary Source
- Article validation through expert research and diverse data:
- Objective and devoid of bias.
- Relevance and consistency with existing research strengthen credibility.
- Potential loss of information in adaptation but reputable publishers ensure accuracy.
- Current findings enhance reliability and validity.
