Wording Question wording should be kept simple, brief and balanced. Each question should attempt to measure one and only one principle. Measurement Scales Measurement scales are used to group responses into common categories. The scales should be balanced and should offer a mid-point. Delivery Methods Delivery methods depend largely on cost factors and response rate requirements.
Response rates vary depending on the delivery method adopted.
A general rule of thumb holds that the more steps asked of respondent to actually respond the less likely a response. For instance mail surveys that offer no stamped return envelopes likely will receive a low response rate, unless some other form of coercion or enticement if used to ensure a better response rate. Data collection methods also depend on the types of questions being asked and on the objectives of the study. Benefits and liabilities associated with different delivery are described below. For instance, mail delivery offers respondents a greater sense of anonymity.
