Week 7: Core Components to Spatial Analysis

Question 1

What are the two parts MAUP is composed of?

Answer 1

• Scale effect
• Zoning effect

Question 1

What is the scale effect?

Answer 1

Statistical analyses based on data aggregated over areas of different sizes will produce different results.

Question 2

What is the zoning effect?

Answer 2

Two sets of zones can have the same or similar areas but very different forms & analyses based on two sets of zones may vary.

Question 3

What is distance decay?

Answer 3

A way of weighting the importance of distance over the given phenomenon.

Question 4

What is spatial autocorrelation?

Answer 4

Correlation among observations of a single variable strictly attributable to the proximity of those observations in geographical space.

Question 5

Why are spatial patterns important?

Answer 5

Reveal relationships

Question 6

What is location quotient?

Answer 6

A simple measure to indicate the relative share of a phenomena in a particular place.

Question 7

Give an advantage of location quotient.

Answer 7

Good visual aid

Question 8

Give a disadvantage of location quotient.

Answer 8

Does not quantitatively determine presence / absence of spatial pattern.

Question 9

How does binary connectivity work?

Answer 9

If areas are adjacent to one another, they get assigned as 1, e.g. w(ij) = 1. If they are not next to one another, they get assigned as 0, e.g. w(ij)=0.

Question 10

What is the best measure of spatial autocorrelation?

Answer 10

Moran’s I
