Dr. Thurman is interested in representing all local ethnicities in her study, and the best sampling procedure to do so is stratified random sampling. This procedure involves dividing the population into subgroups (in this case, ethnicities) and then randomly selecting participants from each subgroup to ensure a representative sample. This way, Dr. Thurman can ensure that her participant pool reflects the composition of the local residents in terms of ethnicity.
