In terms of readability, what does a rating of '4' indicate?

A rating of '4' indicates that the material is readable, suggesting that the intended audience can understand the text without excessive difficulty. In the context of readability assessments, ratings are often assigned based on criteria that evaluate how easily a reader can comprehend the information presented. A rating of '4' suggests that while the content may have some complex terms or concepts, it is generally accessible, allowing readers to grasp the primary messages without significant struggle.

This rating reflects an appropriate level of complexity for writing aimed at a broad audience, indicating that individuals with a standard level of education and familiarity with the topic should be able to read and understand the content without major issues. Higher ratings would suggest even greater clarity, while lower ratings might indicate more challenging material that requires additional effort or background knowledge.
