- Store service-sales person’s responsiveness & knowledge
- What is a reliable but invalid measurement?
- Good scale to measure length
- Exact ruler to measure weight
- Speed & price to measure store service
- Sales person’s responsiveness & knowledge to measure computer satisfaction
Valid Measurement
- Reliability
- Content/Convergent/Discriminant Validity
- Assessment

To collect data for your study, which is more appropriate, self-report or observational, and why?
Would an index work well for any of the constructs? If yes, indicate it (them) and explain the reason.
Can any of your variable be a scale? If yes, indicate it (them) and explain the reason.
Would you be concerned about validity of the measurement? How? (How would you assess the validity?)
