Planned Number of Clusters
|
Before
1,000 participants.
Note the number of participants will be a function of two screening criteria: Whether the messages that participants come up with violate five rules described in the survey body, and whether the participants pass all four (pre-randomization) survey screening questions.
|
After
At least 1,650 participants (messages) after applying screening criteria.
|
|
Field
Planned Number of Observations

Before
Approximately 2,000 messages (before screening criteria are applied).
|
After
The messages will be distributed to at least 1,650*25=41,250 numbers.

Field
Sample size (or number of clusters) by treatment arms
|
