2. Design Likert scales to measure the usefulness of the Grad website. Visit the site at https://www.gerad.ir/ and rate it on the scales that you have developed. After your site visit, were there any aspects of usefulness that you had not considered in devising your scales, what were they and why were they not apparent before you made your site visit?
