Question

ryan gathered data about the age of the different dogs in his neighborhood and the length of their tails. which best describes the strength of the correlation, and what is true about the causation between the variables? lengths of tails for dogs of different ages it is a weak negative correlation, and it is not likely causal. it is a weak negative correlation, and it is likely causal. it is a strong negative correlation, and it is not likely causal. it is a strong negative correlation, and it is likely causal.

Explanation:

• First, analyze the data points. There are only 4 data points which is a very small sample size. A small sample size makes it difficult to establish a strong correlation.
• Second, consider causation. There is no inherent biological or logical reason that a dog's age directly causes its tail length to change in a particular way. Tail length is more related to breed, genetics etc. rather than just age.

Answer:

It is a weak negative correlation, and it is not likely causal.
