Research Design and Statistical Consulting
George M. Diekhoff, Ph.D.

Let a Ph.D. author of two statistics textbooks guide you through a successful dissertation, DNP capstone research, or any quantitative research project!

I’m George M. Diekhoff, Ph.D., the sole proprietor of Dissertation Statistics Helper. 

I’ve helped hundreds of students and professionals complete their dissertations, theses, DNP capstone projects, program evaluations, clinical trials, and other research, and I’d be honored if you’d let me help you too.

Research Design and Statistical Consulting Services:

  • research design 
  • statistical analyses
  • survey construction and hosting
  • dissertation statistics, thesis statistics, and statistical analysis for DNP capstone research projects
  • program evaluations
  • data analysis for clinical trials
  • school- or employment-related projects requiring any form of statistical analysis

Free Consultation


I provide statistical consulting services of the highest quality at the fair and affordable price of $80/hour. Your initial consultation is free. If I believe that I can assist you and you decide to hire me, I will not charge you anything in advance. I complete your work first and you pay me only after you are satisfied with what I’ve done.

You will work with me and me only. Your project won’t be assigned to some nameless “quant” on the staff of one of the big consulting companies. I’ll never off-shore or outsource your project.

My fee is far lower than what you’ll be charged by the big statistical consulting companies. I do a substantial amount of work off the clock and, because I’ve done this so long and know what I’m doing, I am able to work very quickly.

Over the last five years, the average dissertation project has cost $850, start to finish, but a third of the projects I helped with cost under $400.

You don’t have to worry that emailing or calling me with a question will result in “billable hours” because explanations and follow-ups are free. You’ll get unlimited free follow-up support in the form of email, telephone, and videoconferencing.

Statistical Analyses

  • Sample size and power analysis using G*Power and SPSS SamplePower software
  • Data cleaning and screening
  • Descriptive statistics
  • Confidence intervals
  • Significant difference tests (e.g., t-tests, one-way and all factorial ANOVAs, ANCOVAs and other parametric tests)
  • Mann-Whitney U, Wilcoxon T, Kruskal-Wallis ANOVA by ranks, exact sign test, and other nonparametric tests)
  • Procedures for use with heterogeneous variances (e.g., Welch’s robust F test, Games-Howell post hoc comparisons)
  • Correlations (e.g., Pearson, Spearman, point-biserial, chi-square, partial & semi-partial correlations)
  • Psychometric analyses (e.g., Item-total analyses, Cronbach’s alpha)
  • Multiple correlation and regression (direct, stepwise, hierarchical, polynomial regression, analysis of mediating variables and moderator variables)
  • Canonical correlation
  • Binary logistic regression
  • MANOVA and MANCOVA (one-way, factorial, within-subjects, between-subjects, and mixed designs)
  • Discriminant analysis
  • Exploratory factor analysis
  • Cluster analysis
  • Multidimensional scaling analysis

All analyses are done using the latest IBM SPSS statistical software, IBM SamplePower, and G*Power software . 

I can provide you with all SPSS data, syntax, and output files that are generated in your analysis. I will write up your results completely and clearly in APA style, publication-ready or near-ready with format tweaking specific to your target journal. You can use my work verbatim if your university allows that, or you can use it as a model to write your own product. We’ll work together to make sure you completely understand the results of your analyses. You’ll be fully prepared and confident going into your oral defense.


If your program is one of the many that allows their students to work with a methodologist or statistical consultant, I will be happy to work with you. Many graduate and professional programs wisely encourage students to seek out a methodologist or statistics consultant to help with research design and statistics . Most research projects you will undertake after your degree is granted will be collaborative efforts and most research grant budgets include a line for a methodologist or statistical consultant. 

When you hire me, your data will be held in strictest confidence. I will never use your data for my own research. I will never divulge the identity of my clients without their written permission. If you choose me to assist you with your dissertation analyses, we will develop a working relationship that is built on a foundation of mutual respect, honesty, integrity, and trust.
