Final answer:
Vertical analysis is known as common size analysis and horizontal analysis is known as trend analysis.
Step-by-step explanation:
Vertical analysis is frequently known as common size analysis while horizontal analysis is also known as trend analysis. In common size analysis, financial statements are presented as a percentage of a common base, typically total assets or net sales, to allow for easy comparison of items within a single financial statement or across different companies. Trend analysis, on the other hand, focuses on changes in financial statement items over time to identify patterns and evaluate performance.
