13.64 Gangs and homemade weapons. The National Gang Crime
Rescarch Center (NGCRC) has developed a six-level gang
classification system for both adults and juveniles. The six
categories are shown in the accompanying table. The clas-
sification system was developed as a potential predictor of
a gang member's propensity for violence in prison, jail, or
a correctional facility. To test the system, the NGCRC col-
lected data on approximately 10,000 confined offenders and
assigned cach a score from the gang classification system.
(Journal of Gang Research, Winter 1997). One of several
other variables measured by the NGCRC was whether the
offender had ever carried a homemade weapon (e.g., knife)
while in custody. The data on gang score and homemade
weapon are summarized in the table below. Conduct a test to
determine whether carrying a homemade weapon in custody
depends on gang classification score. (Use a = .01.) Support
your conclusion with a graph.
