Dissertation Statistics Helper

Research Design and Statistical Consulting

George M. Diekhoff, Ph.D.

Who am I?

My name is George M. Diekhoff, Ph.D. I'm Regents' Professor of Psychology at Midwestern State University in Wichita Falls, Texas, a medium-sized liberal arts university which emphasizes a balance of teaching and research. I am also the author of two statistics textbooks and the sole proprietor of Dissertation Statistics Helper. I bring the heart of a teacher to the statistical consulting work I provide my clients. You and I will work together to finish your project.

What do I do?

I provide research design and statistical consulting services. Most of my clients are working on their dissertations or other capstone research projects, but I also work with professors on their research and assist both for-profit and nonprofit organizations with program evaluations and clinical trials.
If you are in the proposal development stage of your research I can:

  • assist in reframing your research questions in more productive ways
  • select the best possible research design to collect the data you need--descriptive, correlational, quasi-experimental, or experimental
  • help you develop your measures and design an SPSS data file to hold your data
  • perform power analyses using G*Power and SPSS SamplePower software to determine sample size requirements for your study
  • assist you in preparing your survey and host it for you on my SurveyMonkey account

When your proposal has been approved and your data have been collected, I can:

  • take care of data cleaning and screening
  • thoroughly test the statistical assumptions of the statistics for your study
  • run statistical analyses appropriate to describing your sample and addressing your research questions (including analyses that you might not have thought of)
  • write up the results of the analyses in APA style, ready to cut-and-paste into your dissertation or to serve as a model that you can follow in writing your own results
  • work with you patiently, with the heart of a teacher, to make sure you understand your results
  • help you to prepare the dissertation
  • and I will stick with you until you pass your oral defense.


What's my background and experience?

My Ph.D. is in quantitative experimental psychology, but I've served as methodologist and statistician on hundreds of dissertations, theses, program evaluations, clinical trials, and other research studies in sociology, social services, education and educational psychology, business administration and management, health sciences, biology, clinical trials, organizational psychology, mass communications, and religious studies.

I've published two statistics books (Basic Statistics for the Social and Behavioral Sciences and Statistics for the Social and Behavioral Sciences: Univariate, Bivarate, and Multivariate) , several student study guides, and over 80 peer-reviewed quantitative research articles and book chapters.

What will your project cost?

It depends a lot on when we start working together. Are you still working on your proposal? If I start working with you during the proposal stage, the final total cost of the dissertation might reach $1,200-$1,600. Do you already have your data and just need me to run your statistics and write up the results? That will take much less time and your total cost would more likely be in the $600-$900 range. The average cost of the projects I've worked on over the past five years has been about $800 but about a third of the projects I've worked on have cost less than $400. Sometimes I find that a potential client just needs to be pointed in the right direction and I'm happy to provide that guidance for free. The cost of your project depends on how many research questions you're addressing, what kinds of analyses will be called for, how many variables you're working with, and what shape your data files are in. It is impossible to know exactly where the analyses will lead or what changes the dissertation committee will want to make along the way. However, If you will send me a detailed description of your project, the nature of the data, and your research questions, I'll do my best to estimate your costs. The information I need to make an estimate is typically included in Chapters 1 (Introduction) and 3 (Methodology) of the dissertation proposal and in the proposal Appendices.

Sometimes my work with a client is concluded after only a week or two. Other times I will work with a client for a year or more. Either way, I want to develop a meaningful relationship with you, based on honesty, mutual respect, integrity, and trust. I'll keep you informed of options to save you money along the way, and I'll bill you at an hourly rate that is fair to both of us -- $75/hour for statistics-intensive work and $50/hour for technical editing. The truth is that I do a lot of work off-the-clock because I want to be absolutely certain that I'm treating you fairly. I will complete your project for far less than what the big online stats consulting companies will charge you and your work won't be offshored to some nameless "quant." What's the point, after all, in having an analysis done when the write up is unintelligible?! When you work with me, you will work with me from start to finish!


Is the work guaranteed?

 Yes! I do the work first, submit it to you for your approval, and if you like it, you pay me. If you don't like my work, I hope that you will give me a chance to make it right, but if the work is not what you wanted, you don't pay for it. It's that simple.

Here's how to get started and how we'll work on your project


  • Contact me by Email or go to my Contact page. Tell me a little about your project. I'll get back to you within 24 hours. If you think you haven't heard from me by then, check your spam folder! I pride myself on being available to you quickly.
  • I'll ask you to send me additional information--your research proposal, including research questions, copies of any surveys or instruments you're using, and your data, if you have any. Your identity and everything you send me will be kept absolutely confidential, will not be shared with anyone else.
  • You might not have anything more than an idea. That's fine too. I'm happy to work with you in developing your research proposal from the ground up.
  • I'll review the information you send me within a day or two and will get back to you with my recommendations and estimate of your costs. All of this preliminary work is absolutely free.
  • Once you've seen my recommendations, let me know if you want to hire me. If so, I'll get started immediately. There's no up-front fee. I do the work first and you only pay me if you're happy with it.
  • Once I start your project I'll be in touch with you regularly. We'll quickly develop a relationship based on earned trust, respect, honest communication, and collegiality.
  • After I've completed a block of work for you, I'll send it to you for your approval. If my work isn't what you expected, I'll do my best to make it right. I won't expect you to pay me until you are satisfied with the work I've done for you.
  • We'll continue in this manner until the project is done.
