Tips for Better Analysis

Use larger text samples for more accurate frequency data
Consider the text type (formal, casual, technical) when interpreting results
Compare results with known language frequency patterns
Use case-insensitive analysis for general frequency patterns
Include punctuation analysis for complete text characterization
