Reliability and Validity01:29

Reliability and Validity

12.9K
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.

Structuralism01:26

Structuralism

3.6K
Structuralism, an early psychological theory developed by Wilhelm Wundt and his student Edward Bradford Titchener, sought to dissect the human mind into its most fundamental components. Wundt's groundbreaking work in his laboratory set the stage for Titchener to define structuralism's goal as cataloging the "atoms" of the mind—sensations, images, and feelings—akin to how chemists identify elements of matter.
Titchener's approach to structuralism was unique. He...

Stability of structures

677
In mechanical engineering, the stability of systems under various forces is critical for designing durable and efficient structures. One fundamental way to explore these concepts is by analyzing systems like two rods connected at a pivot point, O, with a torsional spring of spring constant k at the pivot point. This system is similar in appearance to a scissor jack used to change tires on a car. In this case, the arms of the linkage (equivalent to the rods in this system) are entirely vertical,...

Internal Loadings in Structural Members: Problem Solving

1.7K
When designing or analyzing a structural member, it is important to consider the internal loadings developed within the member. These internal loadings include normal force, shear force, and bending moment. Engineers can ensure that the structural member can support the applied external forces by calculating these internal loadings.
To illustrate this, let's consider a beam OC of 5 kN, inclined at an angle of 53.13° with the horizontal and supported at both ends. Determine the internal...

Data Validation01:03

Data Validation

6.4K
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...

Structure of Self01:29

Structure of Self

921
Sigmund Freud's model of the human psyche is often illustrated using an iceberg analogy. The iceberg's visible tip represents the conscious mind, which includes thoughts and perceptions that individuals are immediately aware of. However, the larger, submerged portion of the iceberg represents the unconscious mind, a reservoir of repressed desires, instincts, and memories. According to Freud, human behavior is primarily shaped by this hidden realm.
Components of the Mind: Id, Ego, and...

Summary

This study details methods for evaluating an assessment's internal structure, a key component of validity evidence. Understanding internal structure is crucial for building a strong validity argument to support test usage.

Area of Science:

  • Psychometrics
  • Educational Measurement
  • Psychological Testing

Background:

  • Internal structure validity evidence is a core concept in standardized testing, as outlined in the Standards for Educational and Psychological Testing.
  • This paper focuses on the conceptual underpinnings and statistical methodologies for assessing an assessment's internal structure.

Purpose of the Study:

  • To describe the concepts related to internal structure validity evidence.
  • To present traditional and modern statistical techniques for analyzing the internal structure of assessments.

Main Methods:

  • Review and description of established and contemporary statistical approaches.
  • Explanation of methods for gathering and analyzing internal structure data.

Main Results:

  • Internal structure validity evidence is essential for constructing a robust validity argument.
  • This evidence supports the appropriate use of a test for its intended purpose.

Conclusions:

  • The paper offers practical tools for assessing dimensionality, measurement invariance, and reliability in educational and other assessments.
  • These methods empower practitioners to rigorously evaluate assessment quality.
