Review Questions - Chapter 6 in Jordan text
Terms to Know
- If user attitudes are personal and subjective, why does Jordan say
it's possible to get quantitative (as opposed to qualitative)
data about user attitudes?
- Why is participant time an important consideration in planning a
- Suppose you need participants for an evaluation of a totally new
type of software product -- say the Spanish/English translation
software we discussed with an earlier chapter.
Where would you find representative
users, and how would you convince them to participate?
- Consider the case study described in this Chapter. Suppose the goal was
to perform a "competitive analysis" to determine if this particular
product is any better or worse than competing products.
- What is the purpose of this evaluation (using Jordan's categories)?
- What methods from Chapter 5 would be appropriate, and why? Include both
empirical and non-empirical methods in determining your answer.
- Consider the case study again, from a different angle. Suppose that you
got conflicting information from the questionnaire (where users said
their expectation is to be able to complete a particular type of
analysis within 20 minutes) and the experiments you ran on the
"improved" interface (it always took more than half an hour to
complete the analysis). What would you recommend, and how would
you justify that recommendation?
- On p. 103, Jordan says that the main source of information on user
attitudes toward the product would be the questionnaire. Where
else (which other evaluations) would user attitudes become clear?
Would they be likely to be the same attitudes, or different, and
