Question 4
Marks : +2 | -2
Pass Ratio : 25%
Point out the correct statement with respect to replication.
Focuses on the validity of the data analysis
Focuses on the validity of the scientific claim
Arguably a minimum standard for any scientific study
All of the mentioned
Explanation:
Data replication if the same data is stored on multiple storage device.
Question 5
Marks : +2 | -2
Pass Ratio : 25%
Which of the following step is not required in data analysis?
Synthesize results
Create reproducible code

None of the mentioned
Explanation:
The data set may depend on your goal.
Question 6
Marks : +2 | -2
Pass Ratio : 25%
Which of the following is effective way of checking validity of data analysis?
Re-run the analysis
Review the code
Check the sensitivity
All of the mentioned
Explanation:
Reproducibility addresses the most “downstream” aspect of the research process.
Question 7
Marks : +2 | -2
Pass Ratio : 25%
Result analysis are relatively easy to replicate or reproduce.
True
False
Explanation:
Complicated analyses should not be trusted.
Question 8
Marks : +2 | -2
Pass Ratio : 25%
Which of the following gives reviewers an important tool without dramatically increasing the burden?
Quality research
Replication research
Reproducible research
None of the mentioned
Explanation:
Reproducible research is important, but does not necessarily solve the critical question of whether a data analysis is trustworthy.
Question 9
Marks : +2 | -2
Pass Ratio : 25%
Which of the following problem is solved by reproducibility?
Scalability
Data availability
Improved data analysis
None of the mentioned
Explanation:
More transparency is achieved with reproducibility.
Question 10
Marks : +2 | -2
Pass Ratio : 25%
Point out the wrong statement with respect to reproducibility.
Focuses on the validity of the data analysis
The ultimate standard for strengthening scientific evidence
Important when replication is impossible
None of the mentioned
Explanation:
Replication is particularly important in studies that can impact broad policy or regulatory decisions.
