Paragraph

A science project considered the possible relationship between the weight in grams to the length of the tail in a group of mice. The correlation between these two measurements is r = 0.5. If the weights had instead been measured in kilograms instead of grams, what would be the resulting correlation?
  1. 0.5
  2. 0.5/1000
  3. 0.5(1000)
  4. r makes no sense in this context
  5. None of the above
