For example, on a five-point scale, counting the number of respondents that selected the most

Remote user research has increased the demands for people willing to take surveys, provide website feedback and participate in usability tests. In exchange for their time, users are compensated.

On many high-traffic websites usability problems affect less than 1 out of 10

There are many great books (some classics) on conducting usability tests. These books provide the blueprint for conducting an ideal usability test. One common theme these books present is that when conducting a test you are to act, as best as possible, as a neutral observer. Don't lead users, don't put words in their mouth and don't just tests as a formality to confirm your
