The dramatic dive in parking-ticket revenue in the 2015 is statistically significant. Every revenue report before this 2015 was no more than $35,000 more or less than the seven year average, which is the expected variation. But parking-ticket revenue in 2015 was more than $70,000 below the seven-year average. This indicates that a substantial change outside of normal occurrence happened during this year that caused this drop. Data from the U of M department of parking organized by Jonathan Capriel.
