Hello...please am writing a research project for a friend in the field of accounting but am having issues as per the variables I can use to measure financial reporting. Her topic is " the effects of different depreciation methods on financial reporting. Am using straight line method, sum of years digit method and reducing balance method to capture d methods of depreciation...but d financial reporting part is confusing...d supervisor told her to use one variable to measure financial reporting...but d confusing part is should I choose one type of financial statement such as balance sheet and capture d effects of the different methods of depreciation since financial reporting has to do wit producing reports and statements that discloses an organisation's financial status to stakeholders? or is d supervisor looking towards financial reporting quality ie how does the different methods affect d financial reporting quality of an organisation?...please researchers in the field of accounting and finance, help me out...your contributions are highly needed and appreciated
