Questionnaire Development: A questionnaire is a tool to obtain information from respondents.

It is extremely important for a researcher to know the importance of a proper questionnaire and whether it measures what it is intended to measure.

Composing of a questionnaire is always much more complex than expected and great attention is required to its flow, format and length.

In a review of 748 research studies conducted in agricultural and Extension education, Radhakrishna, Leite, and Baggett (2003) found that 64% used questionnaires.

They also found that a third of the studies reviewed did not report procedures for establishing validity (31%) or reliability (33%).
