METHODOS OF CRIMINOLOGICAL RESEARCH Topic MODULE 3.

INTRODUCTION. Criminology has to offer many of interesting ideas for us to research such as crime rates, crime prevention and other issues in criminal justice system. It involves developing an understanding of crimes through the examination and interpretation of data gathered on research. It may be in the form of natural experiment and field experiment to analyzed its content, corroborate it with further evidence, and use that evidence to develop an interpretation that holds some significant factor to measure and reduce crime..

COMPLETELY RANDOMIZED DESIGN. A completely randomized design is one where the treatments are assigned completely at random so that each experimental unit has the same chance of receiving any one treatment..

A researcher wants to conduct an experiment to determine which form of bullying commonly practice at school. Example : Physical Bullying: such as hitting. slapping, kicking or force to do something. Verbal Bullying: verbal abused, insults, cursing, threats, false rumors, giving names and titles for individual or giving ethnic label..

RANDOMIZED BLOCK DESIGN. An experimental design where the experimental units are in groups called blocks. The treatments are randomly allocated to the experimental units inside each block. When all treatments appear at least once in each block, we have a completely randomized block design..

MATCHED PAIRS DESIGN. A matched pairs design is a type of experimental design wherein study participants are matched based on key variables , or shared characteristics, relevant to the topic study..

Similar Experimental Units. 18 Females. 12 Males.

FIELD EXPERIMENTS AND NATURAL EXPERIMENTS. Field Experiment – are studies using experimental design that occurs in a natural setting. Researcher examine how the manipulation of at least one independent variable lead to a change in a dependent variable in contact of the natural environment..

Natural Experiment. observational study in which an event or situation that allows for the random or seemingly random assignment of study subjects to different groups is exploited to answer a particular question. Natural experiment are often used to study situations in which controlled experimentation is not possible, such as when an exposure of interest cannot be practically or ethically assigned to research subjects..

Conclusion. Experimental research in criminology seeks the relationship between dependent and independent variable and the correlation between a specific aspect of entity and the variable being studied is either supported or rejected. Randomized experiments provides a basis for the statistical methods used in analyzing the data. It also eliminate the selection bias, balances the group with respect to many known and unknown confounding or prognostic variables..

Recommendation. Choose a research question that interest you and would interest your target readership . Make sure to consider the practicalities, the requirements of your program, the amount of time you have to compete the research and how difficult it will be to access sources and data on the topic . Look for relevant participant and make it sure we offer sufficient information and ask the right question before we invite people to participate in our experiment..
