1. Psychometrics: Definition & Test Examples
This lesson defines psychometrics and discusses what is involved in psychometric testing. It also delves into types of psychometric tests, including noting some specific examples of these tests.
2. Classical Test Theory & Item Response Theory
Psychometrics is the study of developing tests and measurements. In this lesson, we'll talk about two different theories of how psychologists can create good tests and measurement: classical test theory and item response theory.
3. The Standards for Education & Psychological Testing
Standards for Educational and Psychological Testing tells readers everything they need to know about testing accurately and ethically, from classroom to counseling office to career.
4. Standardization and Norms of Psychological Tests
Many psychological tests, including intelligence tests, are about comparing your score to others' scores to see how you did. Watch this lesson to find out about two important concepts in psychology: standardization and norms.
5. Types of Measurement: Direct, Indirect & Constructs
How do you measure psychological traits? In this lesson, we'll look at how psychologists measure traits, including direct and indirect observation. We will also explore why psychological traits are so difficult to measure.
6. Reliability & Validity in Psychology: Definitions & Differences
How do validity and reliability contribute to study design in psychology? In this lesson, you'll look at how experiments can fail reliability and validity requirements to get an idea of the challenges behind conducting significant psychological research.
7. The Validity of Measurement: Definition, Importance & Types
How do you know if you are measuring what you actually want to measure? In this lesson, we'll look at what validity is, why it is important, and four major types of validity: face, construct, content, and predictive validity.
8. Threats to External Validity: Sample Characteristics, Stimulus Characteristics & Experimental Arrangements
The goal of research is to generalize the results, but there are several things that can get in the way. This lesson examines three threats to external validity: sample characteristics, stimulus characteristics, and multiple-treatment interference.
9. How Novelty Effects, Test Sensitization & Measurement Timing Can Threaten External Validity
The purpose of research is to find things out about the world at large. But there are several things that can get in the way of external validity. In this lesson, we'll examine novelty effects, test sensitization, and measurement timing.
10. Testing Bias, Cultural Bias & Language Differences in Assessments
Assessments are used to gain useful information about test-takers' knowledge, skills and progress. Sometimes, however, the results of these assessments are incorrect due to biases. This lesson will differentiate and discuss types of testing bias and differences among test-takers that may lead to testing bias.
