Static Analysis Questions And Answers

1⟩ You are conducting a study looking at the group differences in reading ability between three groups of children, all receiving different remedial assistance. You decide that ages will co vary with reading ability, so you do ANCOVA. There are 40 children in each of the three groups. The mean reading score for the whole sample is 42.69. The mean for group 1 is 46.92, for group 2 the mean is 41.89, and for group 3 the mean is 41.05. What is the grand mean?

1. 3.25

2. 2) 43.29

3. 3) 129.86

4. 4) 42.69

10⟩ What are the two main reasons for using ANCOVA?

1. To increase error variance AND to adjust the means on the covariate so that the mean covariate score is the same for all participants.

2. To reduce error variance AND to explore patterns of correlations.

3. To reduce error variance AND to correct the means on the covariate.

4. To reduce error variance AND to adjust the means on the covariate so that the mean covariate score is the same for all groups.

11⟩ You are conducting a study. The IV is attachment style. There are three groups of individuals with different attachment styles; these are secure, dismissing, and fearful. You want to explore whether these differ on their scores of relationship satisfaction. The DV is relationship satisfaction. You are aware, however, that relationship satisfaction is known to co vary with depression. You conduct an ANCOVA with this data. The formula will remove the variance due to the association between which two variables?

1. Secure attachment and relationship satisfaction.

2. Depression and attachment style.

3. Depression and relationship satisfaction.

4. Attachment style and relationship satisfaction.

12⟩ In the example in question 12 there are 3 groups to consider. If you found that the groups differed significantly on reading ability, what might you use to further explore these group differences?

1. You would have to examine partial eta squared to see which of the groups the difference was between.

2. You would have to examine Pearson's correlations to see which of the groups the difference was between.

3. You would have to examine pair wise correlations to see which of the groups the difference was between.

4. You would have to examine pair wise comparisons to see which of the groups the difference was between.

15⟩ The defects found in static testing and dynamic testing are same.

False.

During static analysis, program is not executed yet so defects such as missing requirements,programming standard violation etc. can be found while during dynamic testing, program is actually executed so failures can be found.
