A line chart showing the number of crimes in Las Vegas from 2000 to 2005 may exhibit a totally different trend than a line chart showing the crime rate in Las Vegas from 2000 to 2005.(Crime rate is defined as number of crimes per 100,000 people.)

The number of crimes and crime rate are two different measures. The number of crimes can increase or decrease, but the crime rate may show a different trend because it takes into account the changes in population. For example, if the population of Las Vegas increased significantly during the period 2000 to 2005, the number of crimes might have increased, but the crime rate might have remained the same or even decreased if the increase in population was greater than the increase in crime. Therefore, the line chart showing the number of crimes and the line chart showing the crime rate may exhibit different trends.
