MEET YOUR RESEARCH WHERE IT IS
Where are you feeling stuck?
You don't need to have everything figured out.
Start with the part you need help with.
“I need a solid
“I have data.
Now what?”
Work through the analysis with clear explanations of what your results actually mean.
- Data preparation & analysis
- Model selection & assumptions
- APA-style tables & interpretation
“I need to explain
my findings.”
Build the understanding you need to discuss your methods and respond to feedback.
- Plain-language results walkthrough
- Defense preparation
- Committee-feedback support
RIGOR, WITH A HUMAN SIDE
Support that helps
you understand.
Not just get unstuck.
Your dissertation is your work. Our role is to help you make informed statistical decisions and understand the reasoning behind them.
01
Your question comes first
Choose the method around your research question, design, and data.
02
The reasoning stays clear
Walk through assumptions, findings, and limitations in language you can use.
03
The work stays with you
Keep the syntax or code and the output from every session, in the software your program uses, with explanations you can return to.
HOW WE WORK TOGETHER
Three ways to work.
All of them with you.
01
Work through it together
We run your analysis together in live, shared-screen sessions, in the software your program uses, one step at a time. You keep the syntax or code and the output from every session.
02
Learn to run it yourself
Coaching that builds your own skills: choosing the test, checking assumptions, running the model, and reading the output, until you can do it without help.
03
Get a review
Already have an analysis plan, output, a results chapter, or committee feedback? Dr. Yel reviews it, points out what needs to change, and walks you through the fixes.
Analyses are run with you in live sessions, never done for you behind the scenes. Software: R, SPSS, Stata, SAS, Mplus, and Python.
METHODS WE WORK IN
The analysis your
study calls for.
In R, SPSS, Stata, SAS, Mplus, or Python, whichever your program uses.
Not sure which method fits? That's what the free consultation is for.
The core
toolkit.
The tests most dissertations and theses rely on, run and interpreted properly.
- Descriptive statistics & data screening
- t-tests (independent, paired, one-sample)
- ANOVA, ANCOVA & repeated measures
- MANOVA
- Chi-square & other categorical tests
- Correlation (Pearson, Spearman, partial)
- Linear, multiple & hierarchical regression
- Logistic regression (binary, ordinal, multinomial)
- Poisson & negative binomial regression
- Nonparametric tests (Mann–Whitney, Wilcoxon, Kruskal–Wallis)
- Mediation & moderation (including Hayes PROCESS)
- Power analysis & sample size
Scales, surveys
& latent variables.
Dr. Yel's specialty: building and testing the measures your study depends on.
- Reliability (Cronbach's alpha, omega, ICC)
- Exploratory factor analysis
- Confirmatory factor analysis
- Structural equation modeling & path analysis
- Measurement invariance & DIF
- Item response theory & Rasch models
- Scale development & validation
- Latent class & latent profile analysis
- Latent growth curve models
Nested data
& causal designs.
For data with structure over time or across groups, and for studies that need a credible comparison.
- Multilevel models / HLM
- Generalized linear mixed models
- Longitudinal & growth models
- Missing data: multiple imputation & FIML
- Propensity score matching & weighting
- Difference-in-differences
- Interrupted time series
- Regression discontinuity
- Instrumental variables
- Survival analysis (Kaplan–Meier, Cox)
- Bayesian regression & multilevel models
- Machine learning (prediction & classification)
- Randomized & cluster-randomized trials

ACADEMIC INTEGRITY
Your dissertation is your work,
and it should stay that way.
01
You are the author
Dr. Yel does not write your dissertation or any chapter of it. The research questions, decisions, and interpretations are yours. His role is to advise, teach, and review.
02
You can defend every result
Nothing is handed over unexplained. We work through each method, assumption, and finding until you can explain and defend it to your committee on your own.
03
Your program's rules come first
Programs differ in what outside statistical help they allow. Before we begin, check your program's policy and let your chair know you're working with a statistical consultant. Many students also acknowledge this support in their dissertation.
Dr. Yel declines work that would misrepresent authorship or data, such as writing chapters, altering or fabricating data, or anything your program's policy prohibits.
A FEW THINGS YOU MIGHT BE WONDERING
Good questions.
Honest answers.
Can I get help with just one part of my project?
Yes. Support can focus on a power analysis, an analysis plan, a set of results, or committee feedback. We can also discuss support across several stages.
What should I bring to the first conversation?
Your research questions, your current stage, and any deadlines are a helpful start. A proposal or a summary of committee feedback can also help. You don't need a finished analysis plan.
Will I understand the analysis?
That's central to the process. We walk through the choice of method, assumptions, results, and limitations so you can explain the decisions behind your work.
Which software do you work in?
R, SPSS, Stata, SAS, Mplus, and Python. We work in whatever your program or committee expects, and you keep the syntax or code from every session so you can rerun each step yourself.
Will you run the analysis for me?
No. Analyses are run together in live sessions, with you watching or at the keyboard, so you can explain every step to your committee. Between sessions, Dr. Yel can review your plan, output, or results chapter.
Is working with a statistical consultant allowed?
Usually, though the rules vary by program. You remain the author, Dr. Yel does not write your dissertation, and every result is explained until you can defend it yourself. Check your program's policy and let your chair know you're getting statistical help.
How much will support cost?
The scope depends on your research design, data, and the support you need. Your consultation is the place to discuss deliverables, pricing, and timing before starting.
Can you help with my thesis or capstone?
Yes. Statistical support is available for master's theses and DNP and EdD capstones as well as doctoral dissertations.
