Sampling saves money by allowing researchers to gather the same answers from a sample that they would receive from the population. Non-random sampling is significantly cheaper than random sampling, because it lowers the cost associated with finding people and collecting data from them.
Where do we get our samples for testing?
Some samples are collected by simply running a swab over the affected area. Procedures of this type can be performed in a clinic, in your doctor's office, or at the hospital bedside. The sample may be sent to a laboratory for analysis (although a few tests can provide in-office results in just a few minutes).
