Answer #1
  • The square footage of a home and its price
  • The number of miles run and the number of calories burned
  • Years of education and salary

two values are positively correlated if increase in one is expected to cause increase in the other. We know that as area of house increases, it price also will increase. The more we run, more calories we burn. The more educated you are, more salary you may expect to get. SO, we can say that these are the set of variables that are positively correlated.
