Q: Sets of features spread over an area are said to have a
- locational distribution.
- geographic distribution.
- splatter distribution.
- network distribution.
A: geographic distribution.
If right: Your answer is correct.
If wrong: Your answer is incorrect.

Q: All of the following are types of centers that are calculated for data distribution EXCEPT
- mean center.
- median center.
- central feature.
- absolute center.
A: absolute center.
If right: Your answer is correct.
If wrong: Your answer is incorrect.

Q: The mean center is calculated by finding the average of the x-coordinate values of all the features, and then finding the average of all the y-coordinate values.  The resulting x,y coordinate pair is the mean center.
- True
- False
A: True

Q: In order to add a weight to a center calculation, the features need to have an attribute in their table that expresses the weight as a number.
- True
- False
A: True

Q: What is the tool used to measure the degree to which features are concentrated or dispersed around a geometric mean center? The results are shown on a map as circular rings of one, two, or three standard deviations.
- Standard distance
- Directional distribution
- Standard directional
- Directional mean
A: Standard distance
If right: Your answer is correct.
If wrong: Your answer is incorrect.

Q: What is the tool used to create standard deviational ellipses to summarize the spatial characteristics of geographic features? The ellipses created can show a directional trend.
- Standard distance
- Directional distribution
- Standard directional
- Directional mean
A: Directional distribution
If right: Your answer is correct.
If wrong: Your answer is incorrect.

Q: When some features are more important than others, you can use the Weight Field to reflect those feature differences.
- True
- False
A: True

Q: If the ellipses remain more circular after running the Directional Distribution tool, it's an indication that the data does not have a directional trend.
- True
- False
A: True

Q: Calculating the linear directional mean can result in all of the following outputs EXCEPT
- mean location.
- mean direction.
- mean orientation.
A: mean location.
If right: Your answer is correct.
If wrong: Your answer is incorrect.

Q: In Tutorial 7-5, the length of the output line represents the mean length of the storm tracks.
- True
- False
A: True
