PSE 1 review part 4 (diagnostics)

Which statement(s) is/are true?

The CTT formula is:

• X = T + e

• observable Score = true ability + random error

• O = A + e

• X = T - e

• O = A – e

    Common diagnostic approaches are:

• Physiological measures

• Behavioural measures

• Self-report measures

• Psycho-motoric measures

• All of the above

   Which statement(s) is/are false?

•    Systematic errors are errors that are true for basically everyone and are mostly generalizable (e.g. fatigue)

• Unsystematic errors are mainly individual (e.g. motivation)

• The diagnostic tool of choice has to reach a usable result despite errors.

• In the assessment of human behaviour and psychological functions, there are always errors influencing the result.

• None of the statements are wrong.

   Which statement(s) is/are true?

In classical test theory (CTT)…

• …observable information is used to gain insights into latent variables.

• …errors are assumed to be random, thus, their mean is zero.

• …the errors for items are assumed to be dependent of one another.

• …it is thought that making inferences about things that are not directly observable is likely to be error-prone.

• All statements are true

  The three quality standards are:

• Objectivity

• Valence

• Validity

• Reliability

• Continuity

Which statement(s) is/are true?

• All statements are true.

• Psychometric tools can be questionnaires or interviews.

• The field is devoted to testing, measurement, assessment, and related activities.

• The measurement of skills and knowledge, abilities, attitudes and personality traits is part of psychometrics.

• Psychometrics is a field of study concerned with the theory and technique of psychological measurement.

   Which statement(s) is/are true?

Objectivity is measured by:

• Objectivity of application

• Objectivity of data evaluation

• Objectivity of data interpretation

• Objectivity of administration.

• All of the above.

  Which statement(s) is/are true?

• Reliability describes the overall consistency of a measure.

• Reliability refers to the extent to which a measure assesses what it claims to measure.

• Reliability can be estimated by stability over time measures, equivalent measures and/or internal reliability

• Cronbach’s coefficient alpha is part of equivalent measures reliability.

• all statements are true

   Sensible examples for diagnostic measures in Sport Psychology could be:

• Team Diagnostics -> Cohesion testing

• Individual sport -> Competitive anxiety

• Team Diagnostics -> Intelligence testing

• Individual sport -> Cohesion testing

• None of the above.

Which statement(s) is/are false?

• Cronbach’s coefficient alpha is a measure of reliability based on the average of all possible splits into two equal set of items.

• Cronbach’s coefficient alpha is a measure of reliability based on even numbered items correlated with the score based on the odd numbered items.

• Split-half reliability describes a split measurement at two different points in time.

• Alternate forms reliability tests to which extent two equivalent versions of the test correlate.

• none of the above
