What makes a survey reliable and valid?

Validity looks at the extent to which a survey instrument measures what we want to measure. Reliability considers the extent to which the questions used in a survey instrument consistently elicit the same results each time it is asked in the same situation on repeated occasions.

Are questionnaires high in validity?

A survey can have high reliability but poor validity. A survey, or any measurement instrument, can accurately measure the wrong thing. For example, a watch that runs 10 minutes fast. However, for a survey, or measurement instrument, to have good validity it must also have high reliability.

Do questionnaires have validity?

What is Reliability vs validity?

Reliability and validity are concepts used to evaluate the quality of research. They indicate how well a method, technique or test measures something. Reliability is about the consistency of a measure, and validity is about the accuracy of a measure.

Do random errors affect validity?

How do I determine if my measurements are reliable and valid? In order to determine if your measurements are reliable and valid, you must look for sources of error. Random error consists of chance factors that affect the measurement. The more random error, the less reliable the instrument.

What are some examples of reliability?
