Data: Types and Distribution

1.7K
In biostatistics, data are the observations collected for analysis. There are two main types: parametric and non-parametric. Parametric data, which include continuous (e.g., weight) and discrete numerical data (e.g., number of tablets), assume a particular distribution pattern, often the normal distribution. Non-parametric data do not adhere to a specific distribution and typically comprise nominal (e.g., gender) and ordinal categorical data (e.g., pain scale ratings).

Evolutionary Psychology

Evolutionary psychology explores the origins of human behavior and mental processes by framing them within the context of natural selection, a theory famously propounded by Charles Darwin. This field asserts that many behaviors common across human societies — ranging from instinctive fear reactions to complex social interactions — arose as evolutionary adaptations. These adaptations enhanced the survival and reproductive success of our ancestors, thereby becoming embedded in the...

Defining Psychology

7.8K
Psychology is the scientific discipline dedicated to understanding both observable behavior and the internal mental processes underlying such behavior. It aims to comprehend human nature and apply this understanding to solve practical problems, enhance well-being, and improve societal outcomes. An example of psychology's application is the study of prosocial behavior, such as why and under what conditions individuals might help strangers in need. This process involves describing observed...

Psychology, as a scientific discipline, aims to understand the mind and behavior through rigorous and systematic methods. The foundation of psychological research is evidence-based, relying heavily on the scientific method to derive and validate knowledge. This structured approach ensures that findings are reliable, valid, and applicable to broader contexts.
The scientific method in psychology involves six critical steps: making observations, formulating hypotheses, conducting tests, analyzing...

Area of Science:

  • Computational Social Science
  • Psychological Informatics
  • Behavioral Analytics

Background:

  • Temperament and psychological types are innate characteristics influencing life choices and skills.
  • Traditional assessment relies on questionnaires, but social media offers alternative data sources.
  • Machine learning can infer behavioral types from user linguistic and behavioral patterns.

Observation:

  • This study reviews historical temperament theories and current research on predicting types from social media.
  • A framework is proposed to analyze Twitter data for linguistic and behavioral cues.
  • The framework utilizes David Keirsey's temperament model and the MBTI psychological type model.

Findings:

  • Random Forests with LIWC achieved high accuracy in predicting temperaments: Artisan (96.46%), Guardian (92.19%), Rational (83.82%), and Idealist (78.68%).
  • For MBTI types, Random Forests showed strong performance: E/I pair (82.05%), S/N pair (88.38%), T/F pair (80.57%), and J/P pair (78.26%).

Implications:

  • Social media analysis provides a scalable and objective method for psychological type assessment.
  • Findings can enhance personalized education, career counseling, and conflict management strategies.
  • This research opens avenues for AI-driven behavioral profiling and understanding human interaction online.
