The focus is on selecting the right analysis for your research questions, preparing the dataset properly, checking statistical assumptions, organizing SPSS output, and explaining what the findings mean in clear language. Final deliverables may include: 🔰 Cleaned and coded the dataset 🔰 SPSS output file 🔰 APA 7th style tables 🔰 Statistical interpretation 🔰 Results section support 🔰 Charts and summary findings 🔰 Research-ready statistical report Your raw data should move into structured statistical findings that are easier to understand, present, defend, and use with confidence.

I help clients design, analyze, and develop high-quality research, and turn complex ideas into clear, well-structured writing for dissertations, publications, applications, research reports, and academic essays. With a PhD in Sociology and over 20 years of experience, I support projects across the full research process — from early-stage idea development and study design, through data analysis, interpretation, and manuscript preparation. My work goes beyond editing. I regularly collaborate with clients on building arguments, structuring research, analyzing qualitative and quantitative data, and producing work that is clear, credible, and ready for submission or evaluation. Research Design & Strategy • Research question development and study design • Methodology selection (qualitative, quantitative, mixed methods) • Literature review strategy and conceptual framing Data Analysis • Qualitative coding (NVivo, Atlas.ti, MAXQDA) • Thematic analysis and interpretation • Quantitative analysis (SPSS, Stata, R, Excel) • Data cleaning, structuring, and reporting Dissertation & Research Project Support • Thesis and dissertation development (all stages) • Structuring arguments and chapters • Integrating analysis into written work • Ongoing advisory support Manuscript & Publication Development • Turning research into publication-ready manuscripts • Journal targeting and positioning • Revision and response-to-reviewer support Writing & Editing • Academic editing and restructuring • Essays, personal statements, and statements of purpose • Clarity, coherence, and argument refinement • AI-assisted writing review and humanization I hold a BA, MA, and PhD in Sociology (University of Texas at Austin), with over 14 years of university teaching experience and more than 20 years working in research and analysis. I have served as Managing Editor for Journal of Health and Social Behavior and The Social Science Journal, and as founding editor-in-chief of Premier Journal of Social Science. I work across qualitative, quantitative, and mixed-methods research, including ethnography, interview-based research, survey design, statistical analysis, and monitoring and evaluation (M&E). My consulting work includes: • Dissertation research and analysis • Qualitative coding and thematic interpretation • Statistical analysis of survey and dataset-based research • Policy and applied research projects • Publication-oriented academic work I regularly work with complex, multi-stage projects that require both analytical depth and clear communication. AI-Assisted Writing & Analysis I also work with AI-generated content, helping refine structure, improve clarity, and ensure that outputs are analytically sound and aligned with the client’s voice and goals. This includes AI content editing and what is often described as “AI humanizing” — revising generated text so it reads naturally, avoids repetitive or formulaic phrasing, and reflects a more authentic and credible voice. If you’re looking for someone who can engage deeply with your research — not just edit text, but help you think through it, analyze it, and develop it — feel free to reach out.

I'm a quantitative researcher/scientist who enjoys forming hypotheses, designing studies to test hypotheses, working with data, building statistical models, conducting statistical tests, and producing fully customized graphs/visualizations to show the results of quantitative research. I also enjoy creating computer simulations and building R Shiny apps. I usually do most of my work in R, though I also used Stata, Python, Excel, and SPSS in the past. I did a PhD at Stony Brook University, where I conducted quantitative research in political psychology and political economics and where I received extensive training in statistics and methods of data analysis. My coursework included basic statistics and probability, experiment design, econometrics, linear and non-linear regression models (including binomial models, multinomial models, ordinal models, count models, censored and truncated models), maximum-likelihood estimation, time-series analysis, experiment design, causal inference, instrumental variables, regression discontinuity, structural equation modeling, factor analysis, game theory, computational modeling and simulations. For several years I also taught university courses in math, statistics, and quantitative research methods for social science. I taught students how to use R, Stata, and Excel for data analysis. I taught both undergraduate students and doctoral students. I also have experience with publishing quantitative research in peer-reviewed journals, both as a solo author and as a team. In my freelance consulting work, I have advised clients on study design and statistical analysis for projects in many different fields of research, including psychology, sociology, economics, linguistics, mental health, medical treatment and recovery, business hiring practices, predictive modeling of asset prices, consumer preferences for market research, and others. - James Cragun
