Crime statistics are compiled from UCR data and published annually by the FBI in the Crime in the United States series. The FBI does not collect the data itself. Rather, law enforcement agencies across the United States provide the data to the FBI, which then compiles the Reports.
Watershed Analysis. A watershed is the area of land where all of the water that falls in it and drains off of it goes into the same place or common outlet. A watershed is also defined by topographic divides between two or more adjacent catchment basins, such as a ridge or a crest.
Factor Analysis. Exploratory factor analysis is a statistical approach that can be used to analyze interrelationships among a large number of variables and to explain these variables in terms of a smaller number of common underlying dimensions.actor analysis is based on a correlation table. If there are k items in the study (e.g. k questions in the above example) then the correlation table has k Ã k entries of form rij where each rij is the correlation coefficient between item i and item j.
