Among vulnerable road users in Canada
Consider the following claims that identify—or at least imply—a correlation. For each claim (a) identify the population, (b) identify both variables and their relevant values, and (c) explicitly state the correlation claim.
- A. , pedestrians are significantly more likely to be struck and killed by a motor vehicle than cyclists are.
- B. According to researchers, painting zebra stripes on cows protects the cattle against getting bitten by biting flies. The researchers speculate that this could reduce the use of pesticides.

Consider the following claims that identify—or at least imply—a correlation. For each claim (a) identify the population, (b) identify both variables and their relevant values, and (c) explicitly state the correlation claim.
A. Among vulnerable road users in Canada, pedestrians are significantly more likely to be struck and killed by a motor vehicle than cyclists are.
- Population: Road Users in Canada
- Variables: Pedestrians, and Cyclists
- The number of pedestrians struck and killed by motor vehicles
- The number of cyclists struck and killed by motor vehicles
- Correlation Claim: There is a relationship between Pedestrians, and Cyclists that are struck and killed by motor vehicles in Canada. There are more pedestrians struck and killed by motor vehicles than cyclists.
B. According to researchers, painting zebra stripes on cows protects the cattle against getting bitten by biting flies. The researchers speculate that this could reduce the use of pesticides.
- Population: Cows in research
- Variables: Painting Zebra stripes and pesticides
- The number of cows bitten by biting cows with painted zebra stripes
- The number of cows bitten by biting cows with pesticides
- Correlation Claim: The relationship between painting zebra stripes on cows and the use of pesticides. Painting stripes in cows reduces the of pesticides.
