    This content was COPIED from BrainMass.com - View the original, and get the already-completed solution here!

    Describe and compare the three study designs— exploratory, descriptive, and explanatory.

    1. What biases are built into these three research study designs?
    2. Explain your answer
    3. Provide specific examples to illustrate your points.

    Enter your answers below.

    Exploratory

    <Describe the bias likely in this design.>
    <Explain your reasons for thinking this bias is likely in this design.>
    <Give examples of studies where this bias might appear.>

    Descriptive

    <Describe the bias likely in this design.>
    <Explain your reasons for thinking this bias is likely in this design.>
    <Give examples of studies where this bias might appear.>

    Explanatory

    <Describe the bias likely in this design.>
    <Explain your reasons for thinking this bias is likely in this design.>
    <Give examples of studies where this bias might appear.>

    Would like to have this by Thursday July 23, 2015, along with references.

    Hi ~ I hope this information is helpful to you. Please let me know if there is anything further I can provide to assist.

    Study Designs

    Exploratory (key variables not defined, literature search or focus groups, expands your understanding of subject)
    • Describe the bias likely in this design.
    o Researcher bias, a systematic variation in measurements between observers

    • Explain your reasons for thinking this bias is likely in this design.
    o Since this study design relies upon the subjective process of either selecting literature to review, or posing questions and interpreting and categorizing responses, it can be more subjective than objective in its implementation and analysis. Rather than objectively looking at all available information, researcher may tend to seek out only evidence that supports their ideas.

    • Give examples of studies where this bias might appear.
    o Researcher conducts a focus group to determine why patient satisfaction scores have declined in the cardiology department. Researcher firmly believes it is due to physician behavior, and tends to structure his or her questions in a way to elicit responses that would support that ...

    Solution Summary

    Bias is inherent in all scientific and sociological research studies, and must be recognized and steps taken to reduce the effect on the reported results.
