Question

Scientists are tracking the food consumption of a group of rabbits to determine if there is a correlation between their weight and their daily food intake. The correlation coefficient for the data is r=0.32
.
Which statement is the BEST interpretation of this value?


Lighter rabbits usually eat more food per day than heavier rabbits.

Lighter rabbits most likely eat less food per day than heavier rabbits.

Heavier rabbits most likely do not eat more food per day than lighter rabbits.

Heavier rabbits most likely do eat more food per day than lighter rabbits.

Answer 1

Heavier rabbits most likely do eat more food per day than lighter rabbits.

(r = 0.32 indicates a weak positive correlation: weight and daily food intake tend to increase together, but the relationship is not strong.)
