STATISTICAL CLARITY FOR CONSEQUENTIAL DECISIONS

Turn complex data into defensible decisions.

I help researchers, funders, and mission-driven teams design stronger studies, choose the right methods, and translate evidence into action—without losing rigor along the way.

THE VALUE OF A METHODOLOGIST

Your question comes first.
The model follows.

Good analysis is more than sophisticated software. It begins with a precise question, a study designed to answer it, and methods that match the structure of the evidence.

I join projects at any stage—from an early grant concept to a difficult dataset—and make the statistical reasoning clear, practical, and review-ready.

HOW I CAN HELP

Rigor at every stage of the research lifecycle.

Focused support or end-to-end methodological partnership, calibrated to your team and decision.

01

Research & study design

Build the methodological foundation before data collection begins.

  • Power analysis & sampling
  • RCT and quasi-experimental design
  • Grant methods development
02

Advanced statistical modeling

Fit the model to the question and the real structure of the data.

  • Multilevel & longitudinal models
  • Structural equation modeling
  • Bayesian analysis & sensitivity checks
03

Measurement & psychometrics

Develop measures and evidence that can withstand scrutiny.

  • Scale development & validation
  • Reliability and validity studies
  • Item response theory
04

Evaluation & evidence strategy

Connect analysis to program decisions, policy, and clear reporting.

  • Program and impact evaluation
  • Reproducible reporting pipelines
  • Methods review & team training

AI + STATISTICS

Evaluate intelligent systems with statistical discipline.

AI can accelerate research and operations—but only if quality is defined, measured, and monitored. I help teams build evaluation strategies that go beyond impressive demos.

01

Evaluation designDefine meaningful benchmarks, comparison conditions, and uncertainty.

02

Quality measurementTurn subjective concepts into reliable human and automated metrics.

03

Reproducible workflowsBuild auditable analysis and reporting pipelines with R, Python, and modern AI tools.

ABOUT NEDIM

A statistician who speaks both research and decision-making.

I earned my PhD in Measurement, Statistics, and Methodological Studies from Arizona State University. For more than 15 years, I have partnered with teams across education, psychology, healthcare, law, and technology.

Today I lead Data Analysis & Statistical Solutions, teach graduate research methods and statistics at the University of Massachusetts Boston, and advise early-stage AI teams on evaluation and measurement.
