In today's era, data have become an integral part of our lives. From everyday activities to critical administrative tasks, vast amounts of sensitive and vital information are generated incessantly. Public safety agencies are no exception to this trend, managing a diverse range of data that includes police crime incident reports, traffic accidents, narcotic overdoses, 911 service calls, and various internal administrative procedures.

Organization-specific software provides a certain level of data management capabilities, but the real power lies in the knowledge and expertise of skilled, trained, and professional public safety analysts. With the right skillset, these analysts can decipher order from disorder, balance demand and workload, and enhance planning and research practices.

This course is designed to equip public safety practitioners with industry-standard best practices in crime analytics, data manipulation, and information visualization. Using Microsoft Office (Word, Excel, and Access) and various free open-source software, attendees will learn to create, publish, and understand statistical implications of data-driven products in the realm of public safety. Hands-on practical exercises and problem-solving scenarios are designed to ensure that learning is immersive and impactful.

This course is for anyone interested in crime analysis. It's not a traditional math class, but it does incorporate essential elements of descriptive statistics, providing a crucial understanding of mathematical principles required for successful data analysis.
