Question 1
The SEM for an achievement test is 2.45. Johnny scores 100 and we assume
that 68% of the time his true score falls between + 1 SEM; this
means the confidence interval would be between:
0 and 102.45
2.45 and 100
95.10 and 104.90
97.55 and 102.45
1..25 pts
Question 2
A researcher is concerned with measuring internal consistency reliability and has
decided to use the Kuder-Richardson Formulas with a Likert scale test; this is a
problem because the:
Test does not have dichotomous test items.
Researcher needs a second test for comparison.
Test does not measure internal consistency reliability.
, Researcher is concerned with content sampling error.
