Attitudes, beliefs, emotions, personality traits, etc. that cannot be observed tangibly are called..?
Constructs
The field of psychological measurement, dedicated to finding ways to assign scores to individuals to represent these constructs.
Psychometrics
Describes what the construct is made up of - a description of the internal processes nd behaviors that constitute it
Conceptual definition
This is how the construct is measured in an empirical study
Operational definition
Refers to the consistency of a measure
Reliability
Types of reliability
Test-retest reliability
Internal consistency
Interrater Reliability
Consistency of a measure across time, applicable for measurements of constructs that are assumed to be relatively stable/unchanging for a long period of time
Test-retest reliability
How consistent a measure is within itself
Internal consistency
Consistency of a measure across time, applicable for measurements of constructs that are assumed to be relatively stable/unchanging for a long period of time
Test-retest reliability
If i divide the measure into two, would they be highly-correlated?
Split-half reliability
How consistent a measure is within itself
Internal consistency
Consistency of a measure across different judgements - for measures score by external judges rather than self-scored/automatically scored inventories
Interrater reliability
How well the measure represents the variable its supposed to be measuring
Validity
Does the measurement appear to measure what it claims to measure?
Face validity
Types of Validity (Sigh)
Face Validity
Content Validity
Criterion Validity (Concurrent & Predictive Validity)
Convergent Validity
Discriminant Validity
Construct Validity
Statistical Validity
Internal Validity
External Validity
Is the measurement comprehensive in covering the construct based on how it’s defined?
Content validity
Does the measure correlate with variables that it is conceptually related to?
Criterion Validity
The correlation with variables measured at the same time (person’s extraversion vs number of people in their social circle)
Concurrent Validity
The correlation with variable measures at a late date (new hire’s conscientiousness vs how well they hit job goals a year into job)
Predictive Validity
Correlation with other measurements of the same variable (self-report and peer report personality questionnaires)
Convergent Validity
No correlation with measurements of different variable (conscientiousness vs academic achievement)
Discriminant Validity
How well are the variables operationalized? Do results reflect the conceptual definition of construct?
Construct Validity
How strong is the statistical evidence to support the research results? Is there enough margin of error to cast doubt?
Statistical Validity
Can you truly claim cause and effect or are there confounding variables that might lead to alternate explanations?
Internal Validity
