differences.

Reliability Coefficients


Correlation coefficient (ranges 0 to 1).
Ratio of true score variance to the observed score variance




Reliability =
scores on your test
scores on a “perfect test”
Having more items on your test provides a better
mathematical chance at a higher score.
Error = 1 - reliability
Your test has reliability at .85


85% of the score is accurate/ reliable
15% of the score is error
