Accepted Answer

The answer of Once the analyst collects and examines relevant...

Question 2

Clearance rates are typically reported as ratios.

Accepted Answer

The answer of Clearance rates are typically reported as ratios....

Question 3

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

Accepted Answer

Strategic crime analysts use these types of analysis to identify patterns in crime occurrences over time. Time of day/day of week analysis can reveal the times when certain types of crimes are more likely to occur, while weighted time span analysis can help identify seasonal or annual trends. This information can then be used to develop targeted crime prevention strategies.

Question 4

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

Accepted Answer

To examine seasonality, a crime analyst would need to analyze several years of data to determine if there is a consistent pattern of the problem occurring during certain seasons or times of the year.

Question 5

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

Accepted Answer

Population size alone does not provide a rate of commercial burglaries; it must be combined with the number of incidents to calculate a rate per capita or per unit of population for accurate comparison between different areas.

Question 6

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

Accepted Answer

According to environmental criminology, crime and other problems are not distributed equally across time. Instead, they are often concentrated in specific locations or during certain periods of time (such as weekend nights). This knowledge can inform crime prevention strategies and interventions.

Question 7

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

Accepted Answer

Both tactical and strategic crime analysts examine data by time of day and day of week to identify patterns and trends in crime activity. This helps them to allocate resources and implement effective prevention and intervention strategies.

Question 8

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.

Accepted Answer

This statement is false. Mean and standard deviation can be used for data sets of any size, but they become more reliable as the sample size increases. Generally, a larger sample size leads to a more accurate representation of the population being studied.

Question 9

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

Accepted Answer

Clearance rate is the percentage of reported crimes that result in either an arrest or an exceptional means of clearing the case.

Question 10

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

Accepted Answer

The aftermath refers to the consequences or results of an event, such as a crime, and can include things like damage, injuries, emotional trauma, and the pursuit and capture of a suspect. An offender fleeing the scene would be one aspect of the aftermath of a crime.
