Which of the following is an example of positive correlation?

a: the number of students in a school and the number of stores nearby

b: the age of a child and the height of that child

c: the temperature outside and the number of layers of clothing

d: the age of pets in a home and the number of pets in that home

Option B is right

Step-by-step explanation:

Positive correlation implies when one variable increases the other variable also increases.

Here we find that option A need not be right as number of students in a school may not be the reason for the number of stores nearby

B is right answer as a child becomes more higher as age advances

C is wrong as number of layers of clothing has indirect relationship with the temperature outside

D. The age of pets and number of pets cannot seem to have any association

Hence option B is right
