CRMINILOGICAL RESEARCH 1 & 2
The Etymology of Research:
• French recherche,
from rechercher (to search closely)
where “chercher” means to search;
Meaning of Research
• scientific investigation of phenomena which includes collection, presentation, analysis and interpretation of
facts that links man’s speculation with reality.
• systematic, controlled, empirical and critical investigation of hypothetical proposition about the presumed
relations among natural phenomena
• research is an art of scientific investigation whose aim is to get more informant
Criminological Research
• Criminological research lies at the heart of criminological theory, influences social police development, as well
as informs criminal justice practice.
• the systematic study of crime, criminal behavior, the criminal justice system, and societal responses to crime. It
involves the collection, analysis, and interpretation of data to understand various aspects of crime, such as its
causes, effects, prevention, and punishment
Descriptive Studies
• focuses on describing characteristics or behaviors of individuals, groups, or situations in a
systematic way. It answers "what," "where," "when," and "how" questions but does not explain
"why" the observed patterns occur.
Application in Criminology:
• Descriptive studies in criminology can include mapping crime rates in different areas, analyzing trends in criminal
behavior, or studying demographic characteristics of offenders and victims.
Example: A study that analyzes crime rates in urban versus rural areas over the past decade.
Characteristics of Descriptive Research in Criminology
1. Quantitative
• Descriptive research often employs quantitative methods to collect measurable data, which is then used for
statistical analysis. This approach is particularly useful in criminology for assessing crime rates, victim
demographics, and patterns of criminal behavior.
Application: In criminology, researchers may use surveys, official crime statistics, or crime mapping tools to gather
quantifiable information. For example, a study might analyze crime rates in different cities over time to identify trends
and make data-driven policy recommendations.
Example: A descriptive study that tracks the increase or decrease in property crime rates in a specific city over the past
five years would rely on quantifiable data
2. Qualitative
, • Descriptive research can also utilize qualitative methods to provide a deeper understanding of the research
problem, especially in cases were context, experiences, and perceptions need to be explored. In criminology,
qualitative data may include interviews, case studies, or observations of criminal behavior.
Application: Researchers may conduct interviews with crime victims or offenders to describe their experiences,
motivations, and interactions with the criminal justice system. This can provide insights into crime causation and societal
reactions to crime.
Example: A qualitative study exploring how victims of violent crime perceive the justice system and the impact of these
perceptions on their willingness to cooperate with law enforcement
3. Uncontrolled Variables
• In descriptive research, variables are not manipulated or controlled, unlike in experimental research. Researchers
observe phenomena as they naturally occur, without intervening or altering conditions.
Application: Descriptive criminological research often deals with real-world data where it is impossible or unethical to
manipulate variables. For instance, researchers might observe the behavior of police officers during routine patrols or
collect data on crime without influencing the environment.
Example: A study observing the daily operations of a police department and its impact on community safety without
attempting to change police practices
4. Basis for Further Research
• Descriptive research serves as a foundation for further exploration and can help generate hypotheses or new
lines of inquiry. It provides a clear picture of a problem, which can later be investigated more deeply through
experimental or exploratory research.
Application in Criminology: The findings from descriptive research can lead to new research questions. For example, if a
descriptive study shows a rise in youth crime in a particular area, future research may explore why this is happening or
test interventions designed to reduce youth crime.
Example: A descriptive study on recidivism rates among ex-offenders might lead to further research investigating the
underlying causes, such as lack of employment opportunities or social reintegration programs
Types of Descriptive Studies:
1. Cross-Sectional Studies
• These studies observe a specific population or phenomenon at a single point in time.
Purpose: To provide a "snapshot" of the variables of interest at one specific moment.
Example in Criminology: A survey measuring the public's perception of police effectiveness at a particular time
2. Longitudinal Studies
• These studies involve repeated observations of the same variables over a period of time.
Purpose: To study changes over time and track trends or developments.
Example: A study that follows a group of ex-offenders over several years to measure recidivism rates.
3. Case Report/Case Series
• A detailed account of a single event or individual (case report) or a small group of related cases (case series).
Purpose: To provide detailed descriptive information about a unique or noteworthy occurrence.
