For criminology some of the typical types of research showed to be surveys.
Administrators would reach out to the public through questionnaires or surveys and try to involve the public in the views they have on criminology. Three different types of surveys that were discussed were face-to-face interviews, mailed surveys, and telephone surveys. Surveys are used to reach out to different groups of respondents. Each type of survey has its own advantages and disadvantages. Surveys are used for two purposes. One purpose for surveying is to get public opinions on crime and the criminal justice system. The system uses the viewsof the public to help improve some of the flaws that exist and get opinions on the death penalty, reducing crime, police satisfaction, and reasons why crime exists. Another purpose is to reach out to different high schools and colleges and get the younger population educated on crime and delinquency.
Qualitative methods do have a place in criminology because the purpose of it is to observe and interview. Seeing as criminology requires interviewing to help find statistics, qualitative methods can be combined with surveying and be useful for interviewing the others of the public. For example, qualitative methods are used for interviewing the criminal offenders that are in prisons and jails and, that remain in the public domain.
