Reliability and Validity01:29

Reliability and Validity

12.8K
Reliability and validity are two important considerations that must be made with any type of data collection. Reliability refers to the ability to consistently produce a given result. In the context of psychological research, this would mean that any instruments or tools used to collect data do so in consistent, reproducible ways.

Types of Biopharmaceutical Studies: Controlled and Non-Controlled Approaches

157
Biopharmaceutical studies constitute a vital field aiming to enhance drug delivery methods and refine therapeutic approaches, drawing upon diverse interdisciplinary knowledge. In research methodologies, the choice between controlled and non-controlled studies significantly influences the study's reliability and accuracy.
Non-controlled studies, commonly employed for initial exploration, lack a control group, rendering them susceptible to biases and external influences. In contrast,...

Revisionist Views of Adolescent and Adult Cognition

84
A revisionist approach to Jean Piaget's theory of cognitive development has brought new insights that challenge and reinterpret his established ideas. Piaget proposed that the formal operational stage, emerging in adolescence, represents the culmination of cognitive maturity. During this stage, individuals are said to develop abstract thinking, engage in systematic problem-solving, and show a form of egocentrism, believing others are as preoccupied with their behavior as they are...

Data Validation01:03

Data Validation

5.2K
Data validation is an essential part of a comprehensive assessment. Validation is confirming or verifying and opening the door to gathering more assessment data as it clarifies vague or unclear data. The process of checking and verifying the collected information is called data validation. The primary purpose of data validation is to ensure data is as free from error, bias, and misinterpretation as possible.
Nursing assessment guides are generally based on holistic models rather than medical...

Naturalistic Observations02:30

Naturalistic Observations

15.6K
If you want to understand how behavior occurs, one of the best ways to gain information is to simply observe the behavior in its natural context. However, people might change their behavior in unexpected ways if they know they are being observed. How do researchers obtain accurate information when people tend to hide their natural behavior? As an example, imagine that your professor asks everyone in your class to raise their hand if they always wash their hands after using the restroom. Chances...

Criticisms of the Evolutionary Perspective01:23

Criticisms of the Evolutionary Perspective

145
In a study where individuals posing as strangers offered compliments and proposed casual sex to students, the responses differed significantly based on gender. Not a single woman accepted the proposal, while 70% of the men agreed. This outcome provides a useful scenario to explore through the lens of evolutionary psychology and social learning theory, highlighting the diverse perspectives on human sexual behaviors.
Evolutionary psychology provides one explanation for these findings, suggesting...

Area of Science:

  • Research Methodology
  • Scientific Validity
  • Statistical Inference

Background:

  • Decades of research have focused on internal and external validity.
  • Ongoing discussions highlight the complexity and importance of these validity types in research.

Purpose of the Study:

  • To propose a novel integration of internal and external validity concepts.
  • To introduce a taxonomy of assumptions including theoretical, auxiliary, statistical, and inferential.
  • To re-examine the perceived trade-off between internal and external validity.

Main Methods:

  • Conceptual integration of validity definitions.
  • Analysis of theoretical, auxiliary, statistical, and inferential assumptions.
  • Literature review of recent exchanges on validity.

Main Results:

  • A distinction between less and more important senses of internal and external validity.
  • Demonstration that the internal-external validity trade-off is false for more important validity senses.
  • Identification of a joint increase/decrease of internal and external validity with theoretical emphasis.

Conclusions:

  • The proposed integration offers a nuanced understanding of research validity.
  • Emphasis on underlying theories resolves the purported internal-external validity trade-off.
  • Research practices and advice may need adjustment based on this integrated framework.
