Qualitative, Quantitative and Mixed Method Purpose Statement

Give me some structure and tips so I can create a Purpose Statement, noting the distinctions between the element and Introduction. I need to craft statement according to whether it pertains to a quantitative, qualitative, or mixed methods study:

â?¢ Does the statement begin with signaling words? If so, what are they?
â?¢ Does the statement identify the strategy of inquiry?
â?¢ Does the statement mention the participants?
â?¢ Does the statement mention the research site?

If the study is qualitative, does the Purpose Statement:

â?¢ Focus on a single phenomenon?
â?¢ Use an action verb to convey how learning will take place?
â?¢ Use neutral, nondirectional language?
â?¢ Provide a general working direction of the central phenomenon?

If the study is quantitative, does the Purpose Statement:

â?¢ Identify the independent, dependent, and control variables?
â?¢ Use words that connect the variables?
â?¢ Position the variables from independent to dependent?
â?¢ Provide a general definition of each key variable?

If the study is mixed methods, does the Purpose Statement:

â?¢ Indicate the overall content intent?
â?¢ Discuss the reasons for combining both quantitative and qualitative data?
â?¢ Include the characteristics of a good qualitative purpose statement (as listed above)?
â?¢ Include the characteristics of a good quantitative purpose statement (as listed above)?
â?¢ Indicate the specific types of quantitative and qualitative data collection?
