Final answer:
The statement that the more birds seen outside, the more picnics at a park is a correlation and not causation. There could be a third variable at play, such as good weather, that influences both the presence of birds and the number of picnics.
Step-by-step explanation:
The statement that the more birds seen outside, the more picnics at a park is a correlation and not causation.
Correlation refers to an association between two variables in which a change in one variable is associated with a change in the other variable. In this case, the statement suggests that as the number of birds seen outside increases, the number of picnics at a park increases. However, it does not indicate a cause-and-effect relationship.
There could be a third variable at play, such as good weather, that influences both the presence of birds and the number of picnics. In sunny weather, more people may go to the park for picnics, and it is also likely that more birds will be seen outside.
