How reliable is a questionnaire in research
Questionnaires are generally considered to be high in reliability. This is because it is possible to ask a uniform set of questions. Any problems in the design of the survey can be ironed out after a pilot study. The more closed questions used, the more reliable the research.
What makes something reliable and valid
Reliability and validity are both about how well a method measures something: Reliability refers to the consistency of a measure (whether the results can be reproduced under the same conditions). Validity refers to the accuracy of a measure (whether the results really do represent what they are supposed to measure).
