Describe an “interrupted, task-based protocol”?

When conducting a user-based evaluation, it is best to compare two or more designs against each other.   From an experimental design perspective, the two or more designs being evaluated against each other called the ________________ variables. 

When conducting a user-based evaluation, we attempt to make measurements or observations that will help us determine if one design is better than another. From an experimental design perspective, the things that we measure or observe are called the _____________ variables. 

Find the domain and range.{(5, -7), (5, -5), (-8, -3), (11, 9), (6, 6)}

Which of the following is NOT a key characteristic of evaluative writing, per our assigned reading?

Which best described a closed card sort?

Which type of mock up is the least useful for testing the interaction design of a product? Hint: It is the one that interaction designers generally do NOT create.

The earliest phase of a project may involve the creation of one of several types of artifacts or products to show to users in order to get the idea or concept of a design across to people.  Name one of the products the design team would produce:

Once a design has started, its important to determine if people can interact with various parts of the design, specific functions, or specific features. To determine if people can learn and use a proposed design, the design team would produce what type of artifact?
