We'll start by finishing our "Question of the Week":
How do we compute Moran's I? (And what does it mean?)
Then we'll talk about the ideal survey.
- Let's finish the sample calculation we were working on:
- Now I want to spend a little time talking about what's next:
- We calculate some statistics (Moran's I), for different
measures of poverty or well-being or ....
- We need to decide if these are unusual, or the
result of randomness
- We compare against a distribution, obtained by
simulation. Let me describe what that will entail, using
an example from our class: What's the chance that we have an honors
class of 12 signed up of all women?
- Now on to the final survey. Some comments and ideas that resonated with me:
- Don't let the perfect be the enemy of the good.
- Incentives (Haley has some numbers!)
- Negative versus positive statements: e.g. using "unsafe" versus "safe"
- Do we have a mix of question/statements, or just one kind? Consistency?
- Likert scale
- with or without neutral option?
- with numbers (1-5) or words (agree/disagree)?
- Will large sample size wash out random variation?
- Sample from streets or events?
- York or Monmouth as divider (if we use a divider)?
- Should we "peer test" our survey on a small group?
- I'm going to want to form three teams to wrap up our survey: I'm calling them the
- Location search and advance (LSA)
- Final survey prep (FSP)
- Protocol and incentive (P and I)
teams. Maybe you want to change these around, or consider other teams....
I need leaders for each, first of all. Who will lead these teams?
