Reflections on surveys
“Interviews with benefits”
Easy to pre-code/code
Large sample size = statistical analysis More reliable
Relatively fast (6.5 hrs = 25 surveys vs. 6 hrs = 6 interviews)
+ Analysis of the method

Reflections on surveys
Disadvantages
Not representative
Busy people don’t stop When you survey changes who you survey (chart)
Who administers the survey matters (map)
Bias still possible
E.g., I support separation between users
Time-intensive compared to internet surveys
