Answer: supporting the anecdotal evidence with empirical evidence by examining a range of school handbooks from various public schools
Step-by-step explanation:
The examination of a school handbook from a single public high school represents a piece of anecdotal evidence because it´s only a brief narrative that serves to make a point based on personal observation, providing week support for an argument.
The evidence could be stronger if empirical evidence was provided, meaning one based on scientific research and an adequate sample.
