Problem Statement:
Problem Statement is a clear, concise description of the issue that your research aims to address. What’s the problem? Why it matters? Who is affected?
It sets the foundation for your research by highlighting the gap in current knowledge, practices, or understanding and justifies why your study is necessary.
