Big Data Consulting

At Dr. John McGowan LLC, we bring advanced data analytics into the courtroom. With decades of experience as a researcher and professor, Dr. McGowan has developed expertise in analyzing large and complex datasets using industry-leading tools such as SAS (Statistical Analysis System) and SPSS (Statistical Package for the Social Sciences). These capabilities allow us to uncover insights, validate claims, and present evidence in ways that are rigorous, transparent, and persuasive.

Capabilities

We apply big data and statistical tools across a wide range of applications:

• • Survey Data Analysis: Interpreting structured and unstructured survey responses to extract meaningful trends.
  • Descriptive Statistics: Summarizing large datasets into clear, accessible metrics that highlight central tendencies, distributions, and variability.
  • Inferential Statistics: Testing hypotheses and drawing reliable conclusions from samples to broader populations.
  • Nonparametric Tests: Providing robust statistical insights when traditional assumptions (e.g., normal distribution) do not apply.
  • Data Visualization: Converting raw data into charts, graphs, and visual formats that clarify complex relationships and strengthen courtroom presentations.

Application in Expert Witness Practice

Big data analysis plays a growing role in litigation. At Dr. John McGowan LLC, we use SAS and SPSS to:

• • Merge and analyze very large datasets such as payroll records, medical billing files, or transaction histories.
  • Evaluate employment patterns in discrimination or wrongful termination cases.
  • Quantify economic damages from thousands of individual records in class action or mass tort litigation.
  • Identify anomalies or irregularities in financial records that support forensic accounting and fraud investigations.
  • Provide attorneys with courtroom-ready exhibits that make complex data comprehensible to jurors and judges.

Our Approach

We combine academic rigor with practical litigation experience. The same statistical techniques used in peer-reviewed research—regression models, nonparametric tests, and multivariate analysis—are adapted for use in litigation contexts, always with an emphasis on clarity, accuracy, and defensibility.

By integrating big data analytics into our expert witness practice, Dr. John McGowan LLC offers attorneys a powerful advantage: the ability to handle complex datasets with precision, uncover meaningful insights, and communicate results in ways that are both credible and compelling.
