The document discusses different types of purpose statements for qualitative, quantitative, and mixed methods research. It provides examples of components to include in each type of purpose statement. A qualitative purpose statement should focus on exploring or understanding a single phenomenon or idea, mention the participants and research site, and provide a general definition of any terms. It may use action verbs like "explore", "understand", or "discover". A quantitative purpose statement should specify the variables and relationships being tested without mentioning the methodology. A mixed methods purpose statement should indicate both qualitative and quantitative components and the intent to integrate them.
