Question

1. Roman wanted to assess the internal consistency of his measure of happiness test so he measured reliability estimates by comparing items within his test. He reported a reliability estimate of +0.75. What measure of reliability is Roman using?

1. coefficient alpha
2. r
3. partial correlation
4. ANCOVA

2. Dr. Paul used a computer program to calculate all the possible split-half correlations in her 20-item test of extraversion. The average of those correlations was +0.53. What does this tell us about the reliability of her test?            
3. 1. The correlation is too high to be considered reliable.
   2. The correlation is low, so the test should be considered reliable.
   3. The correlation is too low to be considered reliable.
   4. The correlation is high, so the test should be considered reliable.

Answer 1

Roman wanted to assess the internal consistency of his measure of happiness test so he measured reliability estimates by comparing items within his test. He reported a reliability estimate of +0.75. What measure of reliability is Roman using?

Option A is correct

coefficient alpha

Dr. Paul used a computer program to calculate all the possible split-half correlations in her 20-item test of extraversion. The average of those correlations was +0.53. What does this tell us about the reliability of her test?

Option C is correct

The correlation is too low to be considered reliable.
