Planned Number of Clusters
|
Before
3100
|
After
We expect 3100 individuals to reach the randomization stage of our experiment (which happens in the second survey in our study). Fluctuating recruitment costs (we are recruiting through Facebook ads, whose price varies over time) and attrition between the first and second surveys will determine whether we overshoot or undershoot these numbers.

Sample size (or number of clusters) by treatment arms
|
Before
850 in control, 450 per treatment arm
|
After
We will randomize individuals whose browsing behavior we are not able to track equally across the 6 treatment arms described in the pre-analysis plan. We will randomize individuals whose browsing behavior we are able to track into only 4 of the treatment arms: the control group, the active-choice-no-info group, the active-choice-slant-info group, and the active-choice-quality-info groups. See the pre-analysis plan for details about the design.
It is hard to forecast the number of people who will allow us to track their browsing behavior, but we estimate it to be around 1000.
