Psychometrics – The Study of Design and Evaluation of Assessment Instruments

The study of the construction and evaluation of assessment instruments (ex – test)

Assessment instruments typically employed for diagnostic and/or predictive purposes

Diagnosis – the identification of nature of an illness or other problem by examination of the symptoms, looking at distinctive characteristics and applying them accurately in order to come to a conclusion about where the problem lies within a person - either in their head or their body

Prediction – to make probabilistic determinations of future prospects in light of current performance

Critical difference – time frame, the time period wherein a study takes place; depends on many different factors

POINT – first psych test is more diagnostic than predictive, BUT it is also very predictive (correlation between score on first exam + overall average at end of term is .725)

Standardization – was the test administered under similar conditions in a similar fashion?

Objectivity – does the same response produce the same outcome?

Reliability – consistence over time; would the outcome be the same over time if the attribute being accessed doesn’t change?

Validity – does the test measure what is purports to?

Power – can the tets differentiate between more able + less able respondents?
