Statistics Expert Witnesses

Statistics disputes arise wherever numerical analysis, sampling methodology, or data interpretation becomes central to proving or defending a claim. Class action litigation frequently turns on statistical questions about whether a proposed class shares common issues capable of classwide proof, requiring careful analysis of sampling and aggregation methodology. Employment discrimination, antitrust, and securities litigation often rely on statistical analysis of hiring patterns, pricing behavior, or market data to establish or rebut liability. Damages calculations across many types of commercial litigation depend on statistical and econometric modeling, making the underlying methodology a frequent point of dispute. At the center of most matters is whether a statistical analysis was conducted using methodology that meets accepted standards and supports the conclusions drawn from it.

A statistics expert helps counsel evaluate whether a statistical analysis, sampling methodology, or data model meets accepted standards and supports the conclusions a party has drawn. In class certification disputes, experts can assess whether proposed statistical methods can reliably establish classwide impact. In discrimination, antitrust, and securities matters, experts can analyze underlying data to identify or rebut statistically significant patterns relevant to liability. In damages disputes, experts can build or critique econometric models used to quantify harm. This analysis gives litigators a rigorous, methodologically sound basis for arguments that would otherwise rest on unsupported statistical claims.

Because statistical litigation support spans applications from class certification to damages modeling and survey research, matching an expert's specific methodological background to the case is essential. The statistics professionals Round Table Group can provide are scholars from major universities with expertise spanning biostatistics, econometrics, and survey methodology across disciplines including medicine, business, finance, and engineering, and several have testified on matters requiring rigorous statistical analysis. We've completed more than 75,000 expert searches for litigators, and we apply that experience to match counsel with a statistics expert whose specific methodological background fits the case. Let us help you find the right statistics expert for your case by calling us at (202) 908-4500.

Kinds of Cases We Work On

Round Table Group helps our clients find a wide variety of Statistics expert witnesses for cases like:

01

Price-Fixing Damages Model Draws Challenge.

A group of regional distributors sued a manufacturer for price-fixing, relying on a damages model estimating overcharges across several years of purchase data covering a substantial share of the manufacturer's distribution network. We identified experts with experience in econometric damages modeling, antitrust economics, and regression analysis. The model omitted a control variable for a major input cost shift that explained much of the alleged overcharge, and the court excluded the flawed portion before trial, narrowing the case ahead of settlement.
02

False Advertising Survey Methodology Disputed.

A consumer products manufacturer sued a competitor under false advertising law, relying on a consumer survey purporting to show a large share of shoppers were misled by the competitor's packaging claims. We identified experts with experience in survey research methodology, consumer perception studies, and false advertising litigation support. The survey's control stimulus differed from the tested stimulus in more than the disputed claim, contaminating the confusion rate, and the court granted a motion to exclude it, substantially weakening the case.
03

Actuarial Reserve Model Sparks Reinsurance Dispute.

A reinsurer disputed a ceding insurer's loss reserve estimates for a large book of commercial liability policies, arguing its statistical reserving model understated ultimate losses and shifted disproportionate risk onto the treaty. We identified experts with experience in actuarial reserving methodology, loss development analysis, and reinsurance treaty accounting. The insurer's model relied on loss development patterns from an earlier period with different claims-handling practices, and arbitration adjusted the reserve figures used to settle the treaty accounts.
04

Statistical Process Control Data Disputed.

A component manufacturer sued its raw material supplier after a statistical process control audit found a significant share of incoming batches fell outside agreed tolerance limits, contributing to a costly downstream defect. We identified experts with experience in statistical process control, sampling plan design, and quality assurance auditing. The supplier's sampling plan tested only a small fraction of each batch, well below the rate needed to catch the contracted variation, supporting a settlement covering a substantial share of the defect costs.
05

Bank Challenges Fair Lending Disparity Analysis.

A regulator's enforcement action against a regional bank alleged a statistically significant disparity in loan denial rates across applicant groups, and the bank challenged the analysis underlying the claim. We identified experts with experience in fair lending statistical analysis, logistic regression modeling, and credit underwriting data. The regulator's model omitted a key underwriting variable that, once included, made the disparity no longer statistically significant, and the matter resolved through a narrower consent agreement.
06

Credit Scoring Model Validation Sparks Licensing Dispute.

Two financial technology companies disputed a licensing agreement after the licensee's credit scoring model, built on the licensor's algorithm, produced default prediction accuracy well below the license's guaranteed level. We identified experts with experience in credit risk model validation, population stability analysis, and predictive model performance testing. The licensee had validated the model against a borrower population meaningfully riskier than the agreement's intended use case, and mediation adjusted the royalty structure going forward.
07

Clinical Trial Stopping Rule Disputed.

A drug sponsor sued a data monitoring committee's statistical consulting firm after a trial was stopped early for futility, a decision the sponsor argued relied on a flawed interim analysis. We identified experts with experience in clinical trial biostatistics, interim analysis methodology, and futility stopping-rule design. The consulting firm had applied a stopping boundary using an outdated variance estimate that made the trial appear underpowered, supporting a settlement covering part of a follow-on trial's costs.
08

Ad Attribution Model Dispute Hits Licensing Deal.

Two advertising technology companies disputed a revenue-sharing agreement after the platform's attribution model credited a meaningfully smaller share of conversions to the licensor's data than the licensor's own measurement suggested was warranted. We identified experts with experience in marketing attribution modeling, multi-touch conversion analysis, and advertising data methodology. The platform's model systematically discounted the licensor's touchpoints near another channel's touchpoint under an undisclosed rule, and arbitration adjusted the revenue-sharing calculation going forward.
09

Retailer Disputes Warranty Sampling Audit.

A national retailer disputed an extended warranty provider's audit finding that a significant share of warranty claims submitted over several years were fraudulent, based on a statistical sampling of claim files. We identified experts with experience in statistical sampling design, fraud rate estimation, and extrapolation methodology. The sample had been drawn disproportionately from a single high-complaint store region, skewing the extrapolated fraud rate, and the dispute settled using a corrected, representative sample.
10

Pension Fund Sues Actuary Over Assumptions.

A multi-employer pension fund sued its actuarial consulting firm after a funding shortfall emerged that the fund attributed to overly optimistic mortality and investment return assumptions in the firm's annual valuations. We identified experts with experience in actuarial assumption-setting, mortality table analysis, and pension funding valuation. The firm had continued using a mortality improvement assumption years out of date relative to available industry tables, supporting a settlement covering part of the funding gap.
