Planned Number of Clusters

Before
Because the number of clusters depends on jobseeker response rates to the survey, it is not possible to predict the exact number of clusters. However, the target is 3,000 first-time jobseekers who assess at least 1 hypothetical job.

Update 2023_8_31: During the data collection of the initial 3,000 first-time jobseekers, a filtering issue was discovered in the sample generation procedures that unintentionally excluded a large portion of first-time jobseekers who fit the study criteria, but had recently joined the partner platform. The filtering issue was partially solved in the final survey distribution of the main sample (survey wave 8), which nearly doubled the number of jobseekers who were distributed the survey. The jobseekers who were no longer erroneously excluded assessed at least 1 hypothetical job at nearly double the average rate of the previous 7 survey distributions. With the greater sample size of jobseekers who were sent the survey plus higher response rates, the target number of clusters was surpassed.
In the main sample, we also found heterogeneity in the preferences of first-time jobseekers by the amount of time since joining the partner platform. To further explore this heterogeneity and because a large portion of recent joiners were erroneously excluded, we will collect a follow-up sample of first-time jobseekers who had joined the platform within 60 days of the survey distribution. The target number of clusters for this follow-up sample is 2,000 first-time jobseekers who assess at least 1 hypothetical job. All other study conditions remain the same. The survey distribution for this follow-up sample is scheduled to start today (August 31, 2023). At the time of this update, no surveys for this follow-up sample have been distributed.
