With the goal to evaluate the usability of a new search engine, a marketing team made the following post-survey question: "Tell us, on a scale from 1 to 5, how easy was this site for you to use?"

For you, is this method of asking if something is easy to use, sufficient to solve usability problems?

Exercise 1

Exercise 1

Exercise 1Answer:

You are hired to investigate if the "playlists filters of YouTube" are easy to find.

What kind of usability testing could we do to discover that?

Exercise 6

Answer:

1. Understand the target and the Internet knowledge of users.

2. Test the location of the button with heatmaps (usabilla, optimalworkshop, etc.).

3. Perform user testing to understand the reason of the lack of understanding.

4. Test the location of the button with heatmaps again.5. Compare the scattering and the amount of correct

answers.

Exercise 6

... there we will have:

● The users' answers in a heatmap● The average time used to answer.
