GAINSIGHT ADMIN CERTIFICATION TEST
FOUNDATION 1 AND 2 QUESTIONS AND ANSWERS
2025 GRADED A+.
What does latency mean?,The latent construct of interest is the underlying cause
of the attribute actually being measured.
What is a ratio measurement?,- Most complex
- The 0 is meaningful (variable cannot go below 0)
- EGs: money, age
What is an interval measurement?,- Categories and ranks
- Equal/proportionate intervals between variables
- No true 0
- EGs: temp, IQ
What is an ordinal measurement?,- Provides rank order
- EG: attitude where 1 = approve, 2 = neutral and 3 = do not approve
, 2
What is a nominal measurement?,- Categories
- EG: type of car
What are the 3 levels of test standards for use, development and interpretation of
scales?,1- Foundations (reliability and validity)
2- Operations (admin, scoring, interpretation)
3- Testing applications (policy, use)
What is validity?,- Degree to which evidence and theory support interpretations
for their intended use
- Unitary concept
What is the key feature of classical test theory?,Psych concepts can be perfectly
known but this is near impossible in practise.
What are the assumptions of CTT?,- True score
- Observed score is imperfect reflection of true score
, 3
- Measurement error = distance between true and observed score
What is reliability?,- Consistency of measurements over large no. testings
- Low reliability driven by measurement error
- Test needs to be reliable in order to be valid
How does CTT conceptualise reliability (formula)?,Observed score = true score +
error score
*Where error score = method error + trait error
What is random error?,- Idea of non-optimal individual performance
- Less serious but more common
- Random error estimate = SEM
EGs: distraction, attention lapse
