Description: The data set is a record of the arrests per 100,000 people in each age group in the United States from
1970 through 1999. The variables in the data set are: year (YEAR), arrests per 100 thousand in population (RATE), and
the age group (AGEGROUP). The age groups are defined as (1) 14 and under, (2) 15-17, (3) 18-20, (4) 21-24, and
(5) 25 or over.
The data set could be used to generate descriptive statistics by age group or to do a time series analysis
to predict the arrest rates by age group. These predictions might be used in assessing the need for judicial
system infrastructure changes. Finally, the data could be used to compare age groups with an ANOVA.
This data set is a subset of the data in the data set totarrests.
