Here's why:
* Clarity and Precision: Formal language uses precise vocabulary and avoids jargon or slang. This ensures that the research is clear and easily understood by a wide audience.
* Objectivity: Formal language maintains a neutral tone and avoids subjective opinions or emotional language. This helps to establish the credibility of the research and prevents bias.
* Conciseness: Formal language is concise and avoids unnecessary words or phrases. This makes the research easier to read and understand.
* Professionalism: Formal language is expected in academic and scientific writing. It demonstrates professionalism and respect for the reader.
Characteristics of formal language in research writing:
* Avoid contractions: Use "do not" instead of "don't."
* Use complete sentences: Avoid sentence fragments or run-on sentences.
* Avoid slang and colloquialisms: Use standard English vocabulary.
* Use third person: Refer to the research subject in the third person ("The study found...").
* Be objective and factual: Avoid personal opinions or interpretations.
* Cite sources properly: Use footnotes, endnotes, or a bibliography to give credit to other researchers.
* Use a consistent writing style: Adhere to the guidelines of a specific style guide (e.g., APA, MLA, Chicago).
Examples of Formal vs. Informal Language:
* Formal: The study found that there was a significant correlation between the two variables.
* Informal: The study showed a big connection between the two things.
* Formal: The participants were randomly assigned to the control and experimental groups.
* Informal: We put the people into two groups, one got the new stuff, the other got the old stuff.
By using formal language, researchers can ensure that their work is clear, objective, and professional.
