Final answer:
Directed edges in a graph indicate that the parent's variable value affects the value of the child's variable.
Step-by-step explanation:
True. Directed edges in a graph indicate that the parent's variable value affects the value of the child's variable. This is known as a causal relationship. For example, in a family tree, if a person is the parent of another person, their characteristics, such as genetic traits or behaviors, can influence the characteristics of their child.
A directed edge points from the parent node to the child node, indicating the flow of influence. It is like a one-way street where the parent's variable value determines the value of the child's variable. This relationship is often seen in many fields, including mathematics, computer science, and social sciences.
