Essay

Explain the relationship between app launch, actual user data, and dev/test-set updates.

Question: In a concise analytical response, explain what becomes possible after a mobile app launches and identify both the data source and the sets affected.

Sample answer: After the mobile app launches, actual user data can be used to update its dev and test sets. Thus, launch enables the sets to be revised using data from actual users rather than treating the original sets as permanently fixed.

Key points:

  • The app has been launched.
  • Actual user data is used.
  • The dev set can be updated.
  • The test set can be updated.

Rubric: A strong response clearly states the post-launch timing, identifies actual user data as the update source, and names both the dev set and the test set as updateable. Do not award credit for unsupported claims about methods or outcomes.
