What is the sampling plan for Ohio?
We are conducting proportional stratified random sampling.The number of interviews to complete will vary based on the number of residents in your facility.You will submit a resident census list to Vital Research two weeks before your scheduled interview dates. Only those residents who are in your facility the day you submit your census list can be approached for interview.That is, the list is frozen at that point in time.A random sample of residents will be selected at Vital Research and provided to the interviewers. Interviewers will know how many interviews to conduct from among the list they are given by Vital Research. On the first day of interviews, you will also be asked to provide a list of all residents in isolation or whose legal guardian does not want them to be interviewed.Interviewers will cross those residents off their lists.
