Paper surveys can be the most expensive method of data collection with the lowest response rate, so while this was once the most common methodology, it is now the least common, especially for non-employee populations. Certainly, some populations require paper surveys: employees who are in the field without computer access, customers whose email addresses and telephone numbers are unknown, and so forth. In these instances, NBRI calculates the most cost-effective combination of methodologies.
For employee surveys, a combination of online surveys for those with email addresses and paper surveys for those without email addresses may be recommended. For customer surveys and market research surveys, the minimum number needed to reach valid data from a representative sample, given the anticipated response rate for each methodology whether paper, online, or telephone is typically recommended.
The decision of whether or not to use paper surveys is a fairly easy one: Paper surveys should only be used when necessary, regardless of the application. But when needed, NBRI paper surveys may be combined with online surveys and/or telephone surveys, barcoded for individual tracking, sent to individuals with postage-paid return envelopes, shipped in bulk to multiple locations, and much more!
