How do you calculate the total number of surveys to distribute based on sample size and response rate?

To determine the total number of surveys needed to achieve a desired sample size given a specific anticipated response rate, the correct approach involves dividing the sample size by the response rate. This calculation accounts for the fact that not every individual surveyed will respond.

For example, if a researcher aims for a sample size of 100 respondents and expects a response rate of 20%, the calculation would be 100 (desired sample size) divided by 0.20 (the response rate expressed as a decimal), resulting in 500 surveys. This process ensures that the number of surveys distributed is sufficient to reach the desired number of completed responses, factoring in the likelihood that only a portion of those surveyed will actually respond.

This method reflects a standard practice in survey distribution, which is essential for effective data collection in research and planning contexts.
