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 age (years) length of tail (in ) 2 12 3 0 6 7 10 4 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, calculate the correlation coefficient. But with only 4 data points, it's hard to have a strong correlation.
• Second, consider causation. Age of a dog and tail length (except maybe in some extreme cases not indicated here) are not likely to have a direct causal relationship. A weak negative correlation is more plausible as the data points don't show a very tight - knit pattern.

Answer:

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