Fuzzy numbers etc.

A story Sunday about crime rates at Utah colleges contained erroneous calculations.
The Deseret Morning News misinterpreted computerized crime data tables from the U.S. Department of Education. The tables were titled for school years, such as 2004-05. But they contained data for entire calendar years, such as all of 2004 and all of 2005, not just the school year. That led to inflated calculations.
A chart with corrected information appears here, showing corrected average annual crime rates per 10,000 students for five calendar years between 2001 and 2005.
As reported, data generally show that smaller and rural schools tend to have higher crime rates than larger and urban schools. Experts said that is sometimes because students at smaller schools feel like they know everyone and feel safe, so they may not lock up goods or take other precautions they should.
Corrected data show that rural schools in Utah had an average crime rate of 14.3 crimes per 10,000 students annually, compared to 10.8 in urban areas.
Corrected data shows the average annual crime rate at schools with fewer than 2,000 students was 17.4 per 10,000. In comparison, it was 10.9 at schools with 2,000 to 14,000 students, and 11.1 at schools with more than 14,000 students.
Corrected crime rates at state and major private colleges ranged from a high of 27.8 crimes per 10,000 students at Snow College to a low of 1.7 at Utah Valley State College.
