Question 3

Which statistical mapping classification can be used for point, line, and polygon features?

Accepted Answer

Natural Breaks is a statistical mapping classification method that can be used for point, line, and polygon features. It divides the data into classes based on natural breaks in the data distribution.

Question 4

Which type of map would be most appropriate when depicting robberies occurring at bars, restaurants, and fast food places on a map?

Accepted Answer

Mapping by category is most appropriate for depicting robberies at specific types of locations like bars, restaurants, and fast food places, as it allows for categorization and differentiation of these locations on the map.

Question 5

A type of map in which the relative frequencies of values within variables are displayed.

Accepted Answer

The answer of A type of map in which the...

Question 6

Which mapping classification is MOST appropriate in mapping robbery locations over the last year to get a sense of the data distribution?

Accepted Answer

Density Mapping is the most appropriate method for mapping robbery locations over the last year to show the data distribution. It helps to identify areas with high and low concentrations of crime, allowing for easier identification of crime hotspots.

Question 7

A type of mapping in which the colors of the symbols reflect their values.

Accepted Answer

Graduated color mapping is the type of mapping in which the colors of the symbols reflect their values. This type of mapping is useful when representing data that has continuous values, such as population density or temperature. Graduated size mapping would be more appropriate for representing data with discrete values, such as the number of students in a school district. Single-symbol mapping and density mapping are not related to the use of colors to reflect values, so they are not the best choice.

Question 8

The statistical mapping classification in which the number of features in the database is divided by the number of categories in the range, which results a legend with each category having the same number of features.

Accepted Answer

Quantile classification divides the features into equal number of categories. This ensures that each category has almost the same number of features, making it useful for thematic mapping.

Question 9

The statistical mapping classification that uses mean and standard deviation of the selected variable to determine the break points of the categories.

Accepted Answer

Standard Deviation classification uses the mean and standard deviation of the data to determine the break points, making it a good choice for datasets with a normal or bell-shaped distribution.

Question 10

A type of map in which the relative percentages of values within a variable are displayed.

Accepted Answer

Pie chart maps are the best choice for displaying relative percentages of values within a variable. They are useful for displaying parts of a whole and making comparisons between different parts. Graduated color maps display quantitative data using varying colors, while graduated sized maps use varying symbol sizes to represent numerical values. Bar chart maps use vertical bars to represent data values. While all of these map types have their uses, none of them are specifically designed to display relative percentages of values within a variable in the way that pie chart maps are.

Question 11

Which mapping classification is MOST appropriate in comparing neighborhoods in two different cities and their relative crime levels?

Accepted Answer

Quantile classification would be the most appropriate choice for comparing neighborhoods in two different cities and their relative crime levels. This classification method would divide the crime data into equal groups based on their rank order, allowing for easy comparison of crime levels between the two cities.

Question 12

The mapping classification in which the ranges displayed in the legend are determined by the creator of the map.

Accepted Answer

The Custom classification allows the creator of the map to choose specific ranges that fit the data being displayed, rather than relying on predetermined methods that may not accurately represent the data.

Question 13

The following is not true about mapping by category:

Accepted Answer

Graduated size point mapping is not primarily used in mapping by category.

Question 14

Which mapping classification is MOST appropriate in mapping robbery locations over the last year to get a sense of the data distribution?

Accepted Answer

Natural Breaks classification is ideal for mapping crime data as it uses algorithms to group similar values together based on natural gaps or breaks in the data distribution. This makes it easier to identify high and low crime areas and provides a more accurate representation of the data distribution. Equal Interval, Quantile, and Standard Deviation classifications may not be suitable as they could group together dissimilar values, resulting in a less meaningful representation of the data.

Question 15

The statistical mapping classification that uses geographic information system software to identify the gaps in the distribution of the data

Accepted Answer

Natural Breaks or Jenks optimization is best suited for identifying gaps in the distribution of data. This classification method identifies natural groupings or breaks in the data that occur based on statistical analysis. It allows for the classification of data into distinct groups without any overlap between the classes, making it ideal for identifying gaps or discontinuities in the data distribution. Other classification methods such as Equal Interval, Quantile, and Standard Deviation are not specifically designed for identifying gaps or discontinuities in the data. Custom classification may be used if specific thresholds or breaks are already defined by the user.

Question 16

A type of mapping the does not limit does not limit the analyst to examination of predetermined areas, but shows how incidents cluster and concentrate across space.

Accepted Answer

Density mapping is a type of mapping that displays the concentration and clustering of incidents across space without any predetermined areas. It is also known as heat mapping or hot spot mapping. The density values are represented by varying color shades or intensity, indicating the frequency or density of incidents in a particular area.

Question 17

A type of mapping in which a simplified geographic information system is made available to novice users over the Internet.

Accepted Answer

The answer of A type of mapping in which a...

Question 18

The statistical mapping classification in which the difference between the highest and lowest value is broken down into same-sized ranges.

Accepted Answer

Equal Interval is the statistical mapping classification which breaks down the difference between the highest and lowest value into the same-sized ranges. This is useful when the data has a uniform distribution and the goal is to create a visually appealing map.

Question 19

What two factors can be changed to make the same data can produce visually different density maps?

Accepted Answer

The search radius and cell size can be adjusted to create different density maps. Changing the search radius will affect how nearby points are weighted in the analysis, while changing the cell size will affect the granularity of the map (i.e. smaller cells will result in a more detailed map with more variation in density).

Question 20

A type of map that allows the crime analyst to display several values within a particular variable at the same time.

Accepted Answer

A Chart Map allows the display of multiple values within a particular variable simultaneously, often using charts or graphs on the map itself.
