STATISTICAL CONSULTING

Our statisticians assist doctoral students with any level of statistical knowledge and experience; they are experts at designing quantitative and mixed-methods research, analyzing quantitative data, and interpreting and reporting results. Our statisticians support doctoral students through all research stages–from research proposal development to reporting results. They are committed to your success and are available to answer questions or offer additional support after you receive feedback from your chair or committee. 

WHEN TO WORK WITH A STATISTICIAN

At Dissertation by Design, we understand the importance of statistical expertise in quantitative and mixed-method studies. Collaborating with a statistician can greatly benefit doctoral students, especially during research proposal development. Unexpected changes in research design, sample size, or data collection methods can arise, making it essential to consult a statistician who can guide you through the advantages and disadvantages of different mitigation strategies. Additionally, even if you feel confident in tackling all aspects of your research, having an experienced statistician review your work and provide constructive feedback can provide an extra layer of confidence.

 

How Our Statisticians Can Assist You:

 

Study Design: Our statisticians can help you design a study that effectively addresses your research questions and tests your hypotheses. They will work with you to conceptualize and operationalize study variables, ensuring that your study is robust and aligned with your research objectives.

 

Sample Size and Power Analysis: Conducting a power analysis to justify your sample size and sampling technique is crucial. Our statisticians will guide you through this process, ensuring that your study is adequately powered to yield reliable results.

 

Data Collection Methods: Selecting appropriate data collection methods is key to obtaining accurate and meaningful data. Our statisticians can help you make informed choices, ensuring that your selected methods align with your research goals.

 

Survey Development and Validation: Developing and validating a survey or other research instrument requires careful attention to ensure its reliability and validity. Our statisticians will assist you in this process, ensuring that your instrument is robust and fit for purpose.

 

Statistical Analysis: Our experienced statisticians will help you determine the appropriate statistical analysis techniques for your data. They will conduct the necessary analyses, analyze quantitative data, and report results accurately. Moreover, they will ensure that your results are statistically sound, enhancing the validity of your research findings.

 

Results Reporting: Constructing tables and figures to effectively display your results is crucial for clear and concise reporting. Our statisticians will assist you in presenting your findings in a visually appealing and informative manner.

THE ROLE OF THE STATISTICIAN

After an in-depth complimentary consultation, we will match you with a statistician whose experience complements your specific needs. You will then coordinate directly with your assigned statistician for virtual meetings at a time that is convenient for you, ensuring seamless collaboration throughout your project.

If you are writing your proposal, our statisticians can help you:

  • Conceptualize and design your quantitative research study
  • Develop a conceptual framework
  • Help you understand the rationale behind the choice of statistical tests you will use
  • Ensure alignment among your study aims, research question(s), research design, and data analysis plan
  • Select, design, and/or validate a survey instrument
  • Ensure that your study’s research questions and hypotheses are answerable and testable
  • Plan sampling strategies and data collection processes
  • Develop and plan statistical hypotheses, methods, sampling strategies, and data collection methods

 

If you have collected data, our statisticians can help you:

  • Clean and manage data
  • Conduct statistical analyses
  • Analyze and interpret quantitative data
  • Understand results and relate them to your study’s theoretical or conceptual framework
  • Write up the results of your quantitative research study
  • Construct tables and figures to report results
