Step-by-step explanation:
Analytical procedures are required as part of the overall review at the conclusion of the audit. These procedures include the evaluation of financial information through analysis of plausible relationships among both financial and non-financial data. They are an essential aspect of the auditing process and are primarily aimed at identifying inconsistencies or other potential indicators of misstatements. The analytical procedures are used to assist auditors in forming an overall conclusion as to whether the financial statements as a whole are consistent with the auditor's understanding of the entity.
