B)Arrest rate
C)Percentage found
D)Clearance rate

Answer 2

A

Answer 3

True

Question 4

Which type of chart is best to illustrate the number of thefts by month?

A)Line chart
B)Scatterplot
C)Pie chart

Question 5

Which is not a variable that crime analyst analyze using mean and standard deviation?

A)The number of incidents per area
B)The number of arrests per month
C)The age of offenders
D)The type of crime

Question 6

Crime analysts use three rates regularly: crime rate, arrest rate, and recovery rate.

Question 7

Some problems with using frequency in crime analysis include all except:

A)The most amount of crime doesn't always mean the worst
B)Frequency may distort a problem by comparing unlike areas
C)Variables with a small number of values may be difficult to illustrate in a table or chart
D)Frequency of a variable with small numbers can be meaningless

Question 8

When computing the number of burglaries at apartment units (rate), apartment units is the:

A)Numerator
B)Multiplier
C)Denominator
D)Mode

Question 9

In a city with 50 burglaries in Year 1 and 65 burglaries in Year 2, what is the percent change?

A)15 burglaries
B)15%
C)30%
D)65 burglaries

Question 10

The number of Part I crimes in an area divided by the number of people living in the area multiplied by 100,000 is called:

A)Crime rate
B)Arrest rate
C)Recovery crime rate
D)Clearance rate

Question 11

Most crime statistics published by the FBI on a national level are tabulated

A)By year
B)By month
C)By quarter
D)By type of offender
E)By neighborhood

Question 12

Typically, the largest time unit used in strategic crime analysis to describe a problem is a month.

Question 13

"Anticipatory benefit" is when:

A)Police expect their responses to work
B)A hypothesis about what is expected from a crime prevention response
C)There are combined effects of multiple responses on a problem
D)A particular problem may begin to increase before the responses are complete
E)None of the above

Question 14

Typically, the time unit most often used in strategic crime analysis to describe a problem is a month.

Question 15

The ratio of crimes that have been resolved through arrest and exceptional means is called:

A)Crime rate
B)Arrest rate
C)Recovery rate
D)Clearance rate

Question 16

The number of crimes in an area divided by the number of people living in the area is called:

A)Crime rate
B)Arrest rate
C)Recovery crime rate
D)Clearance rate

Question 17

Three stages of a crime include:

A)Planning, execution, consequences
B)Surveillance, crime act, aftermath
C)Prelude, incident, aftermath
D)None of the above

Question 18

Temporal analysis is important for understanding problems because it provides information about when the crimes are occurring for short term patrol deployment.

Question 19

Which city or cities has the highest crime rate?

A)City A: 2,000 crimes and 50,000 people
B)City B: 1,456 crimes per 100,000 people
C)City C: 3,000 crimes and 200,000 people
D)A and C

Question 20

Depicting crime counts by four week periods instead of by month is:

A)Preferable since four week periods allow equal measurement of time
B)Is used more often in crime analysis
C)Is not preferable since four week periods are difficult to construct from data
D)None of the above

Question 21

Once the analyst collects and examines relevant primary and secondary data, they can then develop a hypothesis

Question 22

Clearance rates are typically reported as ratios.

Question 23

Strategic crime analysts use time of day/day of week analysis and weighted time span analysis to determine long term trends in crime.

Question 24

To examine seasonality, the crime analyst examines several years of data on a problem to determine if there seems to be a similar seasonal pattern across years

Question 25

It is appropriate to use population size to compare commercial burglaries in different areas as rates.

Question 26

According to environmental criminology, most problems are distributed equally across time.

Question 27

Both tactical crime analysts and strategic crime analysts examine data by time of day and day of week.

Question 28

Crime analysts use mean and standard deviation primarily with data sets that include more than 13 cases, because they are more reliable at 13 cases.

Question 29

Clearance rate is achieved in two ways: by arrest and by exceptional means.

Question 30

An offender fleeing the scene is an example of "aftermath".
