C/C three data collection

You have now read about three methods of collecting data: observations, interviews, and surveys/questionnaires. 
Compare and contrast the challenges and utility of these three methods in MOXI. 

Observation:
Challenges: 

• Hard to observe thought process of an individual unless you are talking with them or they are talking aloud.
•  Need to make inferences and they are not always accurate.
• Very time consuming, not efficient.

Utility:

• Unbiased
• First hand account of what is being observed.
• practical 

Interviews:

Challenges:

• Bias/ dishonest
• May disrupt guest and cause a bad experience.
• Can not interview every guest. (limits pool of diversity for evaluation)
• Can be intimidating (depending on the questions and how they are formatted)

Utility:

• Aquire guest's perspective (no need for inferences if you ask them).
• Direct guest feedback. (if the interview involves open ended questions, this may result in guests restating or trying to get the "right" answer).

Surveys/questionnaires:

Callenges:

• Bias/ dishonest
• May disrupt guest and cause a bad experience.
• Can not interview every guest. (limits pool of diversity for evaluation).

Utility:

• Guest's perspective.
• Allows for direct guest feedback

For MOXI I think observation is the most practical and useful in collecting data about a guest's experience. However, it would be nice to incorporate a guest satisfaction survey into some or even one exhibit at a time. That way we can get guest's opinions and improve their experiences. Lastly, I do not think that interviews are helpful at all in a setting like MOXI because they are too intimidating and can be bias or dishonest.
