Response rate (also known as completion rate or return rate) in survey research refers to the number of people who answered the survey divided by the number of people in the sample. It is usually expressed in the form of a percentage.
Example: if 1,000 surveys were sent by mail, and 257 were successfully completed and returned, then the response rate would be 25.7%.
In direct marketing, the response rate refers to the number of people who responded to the offer.
In oncology, response rate (RR) is a figure representing the percentage of patients whose cancer shrinks (termed a partial response, PR) or disappears after treatment (termed a complete response, CR) . In simpler terms RR=PR+CR.
There may be a non-response bias if the response rate is low.

Famous quotes containing the words response and/or rate:
“Love is the victim’s response to the rapist.”
—Ti-Grace Atkinson (b. 1938?)
“Writing a book I have found to be like building a house. A man forms a plan, and collects materials. He thinks he has enough to raise a large and stately edifice; but after he has arranged, compacted and polished, his work turns out to be a very small performance. The authour however like the builder, knows how much labour his work has cost him; and therefore estimates it at a higher rate than other people think it deserves,”
—James Boswell (1740–1795)
