The researcher should use an experimental research design to test whether increased hand washing causes a decrease in illnesses among staff and children in child care. This would involve randomly assigning participants to two groups: one that is instructed to increase their hand washing habits and one that continues with their normal routine. The number of illnesses can then be compared between the two groups to determine if there is a significant difference.
