Intro

Dear Participant,

We are researchers investigating best practices in code review. We would be grateful if you could help our research and participate in our experiment on this subject.

With this experiment:

we compare code review performance under different circumstances
your data will only be stored and used in anonymized form

The code change to review is based on a Java project, so basic Java skills are needed.

Please stay focused on the experiment until it ends, otherwise we won't be able to use your data. Once you start the experiment complete it at once without any interruptions.

It would be great if you could put your browser into full-screen mode now. Often this can be done by pressing F11.

Can we also share your results (in anonymized form) in a publicly available dataset?
(Selecting "yes" allows other researchers and the public to benefit from your answers and effort)

Yes
No

To thank you more concretely for your participation in this experiment, we are going to donate 5 USD to a non-profit organization on your behalf.
(The donation is done only on the behalf of participants whose experiment is valid and complete. The donation will be done at the end of the entire study and will be announced from this Twitter Account).
Please select the organization you prefer:

Thank you and we really hope you enjoy participating in our study!
