Step 1: Establish Face Validity This two-step process involves having your survey reviewed by two different parties.

The first is a group familiar with your topic who can evaluate if your questions successfully capture your topic.

In precision instruments, lab equipment or specialized machinery, even minor inaccuracies can cause problems and lead to inaccurate or incomplete results.

Equipment validation ensures your product will consistently perform within a given range.

One of the proposed survey strategies you may have run across is the suggestion to validate the questions in your survey.

While many organizations may urge you to “add validation” as a quick survey tip, that’s about as far as their suggestion often goes.
