Step-by-step explanation:
Phrases that might be useful in writing the purpose statement for your formal report include "this report investigates", "the research explains", and "this report justifies". Each of these phrases sets a different tone and focus for the report. "This report investigates" suggests a probing, in-depth study; "the research explains" indicates that the report will clarify topics or phenomena, and "this report justifies" implies that the report will provide reasons or evidence in support of a particular point or action.
The purpose of your report is integral to its formation and guides how you present your information and argument. Whether your intent is "to analyze a subject or issue from more than one perspective", "to examine a cause or an effect", or "to conduct research and report results", your purpose statement should clearly convey what your report does and why it is important, considering the needs and understanding of your audience.
Always ensure that your purpose is explicitly stated and that your report's body and evidence align with your stated purpose. By using statistics, objective language, and a clear reasoning strategy, your report becomes a more powerful and effective tool for communicating your intended message.
