In general, the diameter of a tree trunk increases with age. what could be the correlation between the diameter of the tree trunk and age for all trees? a) -0.7 b) 0 c) 0.7 d) 1

C) 0.7

Step-by-step explanation:

Since as the age of tree increases, its diameter of the trunk also increases. So it is a positive correlation. Thus, it's value lies between 0 to 1.

Also, Here not very strong correlation exists as the diameter of trunk also depend on the sunlight and other nutrients. So, 1 is not possible answer.

Hence, 0.7 is the correct answer.

Correlation shows the strength of the relation between two variables.

The value of the correlation lies between -1 to +1.

Correlation is said to be positive if increasing/decreasing of the one variable, also increases/decreases the values of the other variable. Its value lies between 0 to 1.

Correlation is said to be negative if increasing/decreasing the one variable, also decreases/increases the values of the other variable. Its value lies between -1 to 0.
