  • ANOVA (Analysis of Variance)
  • Regression (multiple, logistic, ordinal, hierarchical and more)
  • Bivariate correlation
  • Chi-square
  • t-tests
  • Discriminate analysis
  • Factor analysis
  • MANOVA (multivariate analysis of variance)
  • MANCOVA (multivariate analysis of covariance)
  • Reliability analysis
  • Structural equation modelling
  • Test for moderation and or mediation

Training for Six Sigma Certification

Six Sigma Certification Training for Black, Green, and Yellow Belt Candidates

Bryan is a Certified Lean Six Sigma Black Belt and can help you prepare for your test. He uses the DMAIC project methodology, which has five phases. He will take you through the methodology and help you learn to understand and apply it:

  1. Define the problem, the voice of the customer, and the project goals.
  2. Measure key aspects of the current process and collect relevant data.
  3. Analyze the data to investigate and verify cause-and-effect relationships. Determine what the relationships are, and attempt to ensure that all factors have been considered. Seek out the root cause of the defect under investigation.
  4. Improve or optimize the current process based upon data analysis using techniques such as design of experiments or mistake proofing, and standard work to create a new, future state process. Set up pilot runs to establish process capability.
  5. Control the future state process to ensure that any deviations from target are corrected before they result in defects. Implement control systems such as statistical process control production boards, visual workplaces, and continuously monitor the process.


Director of Nursing Practice

For DNP students:
You need to start writing your DNP proposal or you need to analyze your data and prepare for your defense; you know this, but you have been hesitating or feel uncertain….

How do I begin? What do I do now that my data is collected? How do I put this all together and prepare for my defense? No matter where you are in your DNP project, I can help you move toward the ultimate goal: your DNP degree.

I can help you develop your PICOT:
To formulate questions in Evidence Based Practice, use the PICOT format.

  • Population/Patient Problem: Who is your patient? (Disease or Health status, age, race, sex)
  • Intervention: What do you plan to do for the patient? (Specific tests, therapies, medications)
  • Comparison: What is the alternative to your plan? (e.g., No treatment, different type of treatment, etc.)
  • Outcome: What outcome do you seek? (Less symptoms, no symptoms, full health, etc.)
  • Time: What is the time frame? (This element is not always included.)

Your PICOT question will fall under one of these types:

  • Therapy/Prevention
  • Diagnosis
  • Etiology
  • Prognosis

We can work together to develop your DNP proposal and defense sections.


Statistical Programs

SPSS – Statistical Package for Social Sciences

SPSS is a comprehensive statistical package with substantial programming and data-transformation features. Bryan can assist you with the following:

  • Programming (e.g., computation, recodes, conditional execution and looping)
  • Statistical analysis (e.g., descriptive statistics, tables, regression, t-test, ANOVA, factor analysis, logistic regression and time series)
  • Graphics (e.g., histogram, pie chart, scatter plot, line graph, and 3-D plots)
  • Utilities (e.g., sorting, merging and table lookup, transposition and displaying the dictionary for an SPSS system file)
  • Spreadsheet appearance: Using interactive graphical SPSS, data are displayed in a matrix similar to a spreadsheet.


The interactive data analysis program runs on a variety of platforms. It can be used for both simple and complex statistical analyses. STATA uses a point-and-click interface as well as command syntax, which makes it easy to use. STATA also makes it easy to generate graphs and plots of data and results.

Analysis in STATA is centered on four windows: the command window, the review window, the result window, and the variable window. Analysis commands are entered into the command window and the review window records those commands. The variables window lists the variables that are available in the current data set along with the variable labels, and the results window is where the results appear.

Student Reviews

“Bryan was terrific Very upfront and thorough – great reporting – I will recommend to my cohort – Incredible job and quick I will say that it was very inexpensive – I think you could charge more – I got a bunch of other quotes – One was cheaper but did not seem legit – One was close to $2,000.” – Katie Boone

“Bryan’s mastery of statistics was apparent through the ease with which he grasped and understood the statistical challenges I was grappling with. He not only worked with me through every step of my problem, but he also availed himself almost instantaneously to answer my questions the entire time we were working together. As a result of professionalism, advice and assistance with conceptualizing my design approach, I feel very confident in the quality of the work produced.” – Emma, Old Dominion University

“After switching from another statistician to Bryan Hamilton, I am incredibly impressed with Bryan’s feedback and recommendations. Bryan was quick to respond to my email and returned my revisions very quickly, considering it was Thanksgiving week. I appreciate that Bryan actually responds with a friendly tone and provides a response with more than one sentence. When others reply with one-sentence responses, this implies that they are too busy to communicate, even when they are being paid for their services. Bryan’s responses are also very professional. I am excited to continue to work with Bryan Hamilton.” – Graduate student, Grand Canyon University

“I have already recommended Bryan to my classmates. He did a great job and was very knowledgeable, patient and accessible.” – Adi Nkwonta

“Wonderful value and superb response to questions and concerns. Would heartily recommend to anyone needing a  quality value-driven stats service!” – Katherine Callahan

“Bryan has gone above and beyond to help with my dissertation edits. He was always available when I had questions and would reply immediately, including nights and weekends. There is absolutely no way that I could have ever made it to this point without his assistance. Bryan was very understanding and would help break things down and explain how to improve my writing. His statistical knowledge is outstanding and his ability to effectively communicate is amazing. I have been very pleased with his services and plan to use him again in the near future. I would highly recommend Bryan if you are stuck and need some help moving forward on your dissertation. Thanks, Stephen”

“I have been working with Bryan since 2013. In that time, Bryan’s statistical knowledge and skill at teaching has allowed me to pass all my exams and tests as part of my PhD. Simply put, without Bryan’s help, I would not have been able to progress with my PhD, simple as that. Being a mature student and not having looked at statistics for several decades, having Bryan’s patient and effective coaching gave me the confidence to tackle what would have been an impossible subject to pass. And not only did I pass, but I attained a GPA of 4.0 with straight A’s in all of my courses.”

“Don’t bother looking at the competition. Period. There’s no one who comes close. You won’t regret making the decision to work with Bryan – for me, it was one of the best academic decisions I’ve ever made.”

“Bryan is very easy to work with. He takes the time required to help you fully understand the problem at hand. He is very knowledgeable and is extremely good at working through a problem in such a way that you are the one actually solving the problem with a few pointers from Bryan to keep you going in the right direction. I would recommend Bryan to any student needing additional assistance.”

“I was lost in my class and did not totally understand what the instructor was requiring for my research paper. I found Bryan and my anxiety in the class decreased.”

“Bryan is patient and explains the process in a manner that I can understand. I love all the tools that he utilizes and it helps me to connect the pieces.”

“I was ready to quit my Master’s program but with Bryan’s guidance I now feel confident enough that I can continue in the program. I have already registered for my next research and have informed Bryan that I will once again need his expertise.”

“If you are looking for a tutor that has flexible hours, patient, knowledgeable and worth his fees, Bryan is your guy.”

“Bryan is supportive and patient. He is always available when you need his expertise in the areas of statistics and your thesis and or dissertation research. I highly recommend him.”

“Working with Bryan was a fantastic experience. His background really helped to connect with where I was coming from. From helping to make sure I understood basic to more complex statistical concepts, to offering feedback through my dissertation process – it was a joy to work with him. He’s very capable, flexible and easy to communicate with!”
