Sample size (or number of clusters) by treatment arms
We exclude individuals that fail attention checks. Additionally, we exclude individuals that have never worked in the healthcare industry at a skilled nursing facility as an RN, LPN, or CNA. We also exclude participants who do any of the following: (i) report a probability above 100, (ii) report a time to complete a task above 4 hours, (iii) report a historical wage greater than $100 per hour, or (iv) give answers that are self contradictory as explained in our analysis plan. We will continue to run the experiment until either (i) we have at least 240 completed surveys that meet these criteria or (ii) we have continuously run our survey through February 1, 2023 without reaching 240 complete surveys that meet these criteria. Because of our filters, and because of the nature of our online-survey vendor, we cannot precisely control the number of participants or end date of our experiment.
In the first stage, participants are randomized, with equal probability, into two groups regarding the experience level of a hypothetical nurse. If we have exactly 240 participants, this implies ~120 participants per group.
In the second stage, participants are randomized into a control group or one of four treatment groups. Each group sees different information about a hypothetical facility. We randomly assign one-third of participants to Control. We randomly assign the remaining participants with equal probability to one of the four treatment groups. We thus allocate participants as follows: Control, one-third (~80 participants); Treatment 1, one-sixth (~40 participants), Treatment 2, one-sixth (~40 participants), Treatment 3 , one-sixth (~40 participants), Treatment 4, one-sixth (~40 participants). Most of our analysis combines treatments 1 and 2 together into one condition and treatments 3 and 4 together in one condition. See our analysis plan for details. Note that because of our filters, and because of the nature of our online-survey vendor, we cannot precisely control the number of participants or end date of our experiment. In particular, it is very likely we will not end up with exactly 240 participants so these distributions are approximate.
