ArcMap comes with many symbols for specialized industries.
True
False

The symbols used on a map largely determine how easy it is to understand.
True
False

All of the following statements about labels are true, except one. Which one?
Zooming in or out on the map changes the position of labels.
Label placement is based on the number of features being displayed.
You can reposition labels as desired.
Label placement is determined by the current map extent.

If you want to label a feature on a map but you don't have the feature in your database, which option below can you use?
Annotation
MapTip
Interactive feature label
Dynamic feature label

You are mapping all schools within a county. The schools attribute table does not have a field that contains the school names. You can display the school names on the map anyway.
True
False

Which of the following statements describes the natural breaks (Jenks) classification method?
Each class has the range of values you specify.
Each class contains an equal number of values.
Class ranges are determined by the data.
The interval between values in each class is the same.

What three things must you decide when symbolizing a quantity attribute in ArcMap?
The layer, the attribute, and the number of classes
The classification method, the number of classes, and the number of layers
The type of symbology to use, the classification method, and the number of classes
The number of features to show, the size of the symbols, and the color of the symbols

Which legend type would you use if you wanted to group world countries into total population categories?
Dot density
Unique values
Single symbol
Graduated colors

All of the following example attributes contain categories, except one. Which one?
Diameter: 15, 21, 39, 42
Vegetation: forest, grassland, marsh
Toll road: Yes, No
Rank: 1, 2, 3, 4, 5

Open a new map document. Add the CensusTracts layer from Symbols\Jacksonville.gdb. Symbolize the census tracts with graduated colors using the AGE_22_29 field, natural breaks method, and five classes. Normalize the data by area.

Which statement below is true about the resulting map?
The density of young adults is greatest around the periphery of the map.
Most of the census tracts are grouped into the lower classes.
Most of the census tracts are grouped into the higher classes.
The density of young adults is evenly distributed on the map.

For point features, you can modify all of the symbol properties below, except one. Which one?
Color
Fill pattern
Size
Angle

Why might you create a layer file?
To be able to easily reuse the layer's symbology on other maps.
To print the map.
To save the layer.
To create feature labels.

On a map of property values, if you wanted to make sure that one of the class breaks occurred at 1 million dollars, which classification method below would you choose?
Manual
Natural breaks
Equal interval
Quantile

Normalization is the process of dividing one numeric attribute value by another and then mapping the resulting values.
True
False

You are symbolizing a polygon layer with graduated colors according to some attribute. Some of the polygons are large, while others are small. What can you do to make sure the patterns on your map are not simply a reflection of the different polygon sizes?
Symbolize by unique values instead of graduated colors
Use at least seven classes
Normalize the attribute by area to map density
Choose a color ramp with lighter colors

According to this classification histogram, which class contains the attribute value with the highest frequency?

2.00 - 2.38
2.38 - 2.74
2.74 - 3.19
3.19 - 6.00

On a thematic map, features are symbolized by an attribute.
True
False

One way to distinguish features within a layer is to symbolize them according to an attribute.
True
False

An advantage of annotation is that you can label many features at once.
True
False

Open a new map document. Add the Florida feature class from Symbols\Florida.gdb. Symbolize the counties with graduated colors using the AGE_18_21 field, Quantile method, and four classes.

What is the highest value in the first class?
1,355
3,351
5,458
7,817

When using dots to represent quantities, all of the following statements are true, except one. Which one?
The closer the dots are together, the greater the density.
The more dots in an area, the greater the quantity.
The dots are associated with feature locations.
Each dot represents a specific count or amount.
