What is a umux score?
UMUX is a simple four-item questionnaire listing two positive and two negative statements that respondents rate agreement with on a five or seven-point Likert scale. UMUX-Lite is the shorter version which only contains the positive statements.
How do you standardize a questionnaire?
A standardised questionnaire is one that is written and administered so all participants are asked the precisely the same questions in an identical format and responses recorded in a uniform manner. Standardising a measure increases its reliability.
Are there disadvantages in using a standardized questionnaire?
While there are many positives to questionnaires, dishonesty can be an issue. Respondents may not be 100% truthful with their answers. This can happen for a variety of reasons, including social desirability bias and attempting to protect privacy.
