Four Primary Factors for Analysis
Four Primary Factors for Analysis
1. Form - refers to elements that comprise writing; slant, angles, lines, curves, connections
2. Line quality - the type of writing instrument used and the pressure exerted along with the flow and continuity of the script
3. Arrangement - spacing, alignment, formatting, and distinctive punctuation
4. Content - spelling, phrasing, punctuation, and grammar
