Question

Categorizing Relationships between Variables
Which scenarios have a negative correlation? Check all that apply.

the number of calories consumed and the amount of weight lost by a person
the temperature outside and the number of pool guests
the number of children assigned to a class and the number of desks
the price of rice and the number of penguins at the South Pole
the thickness of the ice on a lake and the likelihood of falling through the ice

Answer 1

Negative correlation applies to:
- the number of calories consumed and the amount of weight lost by a person (more calories → less weight lost)
- the thickness of the ice on a lake and the likelihood of falling through the ice (thicker ice → lower likelihood)

The others are positive (temperature vs pool guests, children vs desks) or unrelated (price of rice vs penguin count).
