Quiz 1

Question 1

Thematic map

Answer 1

displays the spatial pattern of a theme or attribute

Question 2

Answer 2

emphasize the geography location (topoographic maps, elevation, location of water)

Question 3

17th century maps

Answer 3

show trade winds and monsoons

Question 4

19th century maps

Answer 4

lists, organized, geography of force, titles

label placement
map symbolization
cartographic design

Question 6

Communication perspective emphasis on

Answer 6

map user
choice of symbol
design choice

Question 7

what are the scales of measurements

Answer 7

nominal
ordinal
interval
ratio

Question 8

Nominal data

Answer 8

categories
no quantitative operators
kinds of things (race or ethnicity)

Question 9

Orinal data

Answer 9

baed on different disciplinary news
categories can be ordered then organized

Question 10

Interval Data

Answer 10

linked to quantitative
has an arbitrary zero

Question 11

Ratio

Answer 11

distances and area (0 is not arbitrary)
inferential statistics
choropleth maps

Question 12

what are the common methods of data classification

Answer 12

Equal interval
quantiles
mean-standard deviation
maximum breaks
natural breaks

Question 13

Equal interval

Answer 13

each class occupies an equal interval along the number line
uniform distribution
straight forward
fails to consider how data are distributed along the number line

Question 14

Quantiles

Answer 14

rank-ordered and equal numbers of observations are placed in each class
same number of observations in each class
solves problem of empty classes
hard to tell quantile from legend

Question 15

mean-standard deviation

Answer 15

data are distributed along a number line
classes are formed by repeatedly adding or subtracting the std from the mean

Question 16

Maximum breaks

Answer 16

ordered raw data from low to high
differences between adjacent values are computed and the largest of these differences serve as class breaks

Question 17

natural breaks

Answer 17

more common
want to minimize the distance between data values in the same class and maximize differences between classes

Question 18

Benefits of color

Answer 18

• Improve an interesting display
• Subtitle discriminations in complex displays
• Draw attention to warnings
• Color coding can emphasize the logical organization of information
• Makes designs more visually interesting and aesthetically appealing

Question 19

Analogous

Answer 19

adjacent colors on the wheel (opposite on wheel)

Question 20

complementary

Answer 20

opposing colors (opposite on wheel)

Question 21

Saturation

Answer 21

amount of gray in a hue
as saturation increases, the amount of gray decreases

Question 22

Brightness

Answer 22

perceived amount of light coming from a source
amount of white in a hue
as brightness increases, the amount of white increases

Question 23

Luminance

Answer 23

measured amount of light coming from some region of space
can be physically measured

Question 24

Color is irrelevant to

Answer 24

perceiving object shape
perceiving object layout in space
objects are moving

Question 25

Color is used to

Answer 25

label (noun)
measure (quantity)
represent or imitate reality (representation)
enliven or decorate (beauty)

Question 26

Just noticeable different

Answer 26

measures whether a color of a particular size should be noticeably different to a particular percent of the population

Question 27

Choropleth maps

Answer 27

phenomena that have spacial variation that coincides with the boundaries of enumeration units
Data values depicted for enumeration units must be viewed as “typical” rather than being uniform throughout enumeration units

Question 28

When to use choropleth maps

Answer 28

Where the visual intensity in shading is directly proportional to the magnitude of the data values
Shading often varies
A degree of subjectivity may be allowed in setting the minimum shading density to enhanced visual interpretation

Question 29

Symbol of reference

Answer 29

look like data or concepts
airplane for airport

Question 30

Symbol by convention

Answer 30

railroads
water is blue

Question 31

Proportional Symbol Map

Answer 31

size of a proportional symbol reflects the actual data value
data occurs as points

Question 32

Graduated Symbol

Answer 32

quantitative values are grouped into classes
all features are drawn with the same symbol
you can’t discern the value of individual features
classes are used

Question 33

Circle advantages

Answer 33

most compact symbol
scaling is easy
visually stable
smooth feel
