How to Choose a Biostatistics Consultant for Medical Research

Choose a biostatistics consultant who can explain how the analysis will answer your research question, document the assumptions, and agree on reproducible deliverables before work begins. Compare the written scope and relevant experience—not promises of significant results or journal acceptance.

Disclosure: StatMedAnalysis provides paid statistical consulting. This is our practical procurement checklist, not an independent ranking of providers or a validated scoring instrument. You can use it with any provider, including your institution’s statistical support unit.

Which kind of support fits your study?

Start with the decision you need to make. A request to “analyze the data” can cover very different work.

• Before recruitment: discuss the outcome, study design, feasibility, and sample-size assumptions. See study design support.
• Before analysis: resolve variable definitions, data structure, and missing information. See dataset readiness assessment.
• For an existing analysis: identify what requires independent checking and whether the original code is available. See results validation.
• After peer review: separate requests for clarification from requests that require new analyses. See statistical reviewer-response support.

Your institution may already offer suitable support. Ask about eligibility, waiting times, and whether its remit covers your study before commissioning external work.

Six questions to ask before accepting a quotation

1. Who will do the work, and what experience is relevant?

Ask who will perform and review the analysis, which methods they have used, and how they handle questions outside their expertise. Request a permitted example of an analysis plan or report, with confidential information removed. A long software list alone does not establish study-specific competence.

2. What is included in the scope?

List the research questions, datasets, outcomes, analyses, and expected outputs. Ask whether cleaning, sample-size justification, interpretation, manuscript text, and reviewer revisions are included or separately quoted. Agree how a change in the question or dataset changes the work and cost.

3. How will analytical decisions be documented?

Ask when the analysis plan will be agreed, how missing data and assumptions will be assessed, and how deviations will be recorded. For an already analyzed dataset, be explicit about what has been seen and which analyses are exploratory. Do not describe a retrospective decision as prespecified.

The American Statistical Association’s ethical guidelines emphasize honest representation of competence, appropriate methods, transparent limitations, and protection of confidential information. They are professional guidance, not an endorsement of any provider.

4. What will you receive at handoff?

Specify the agreed code or reproducible project files, software versions, variable definitions, cleaning decisions, tables, figures, and interpretation. Clarify licensing or institutional restrictions before agreeing to deliverables. Use our reproducible analysis handoff guide to make the list concrete.

5. How will access to research data be managed?

Before transferring files, confirm the approved environment, authorized users, transfer method, retention arrangements, and institutional approvals that apply to your project. An NDA alone does not establish that a workflow meets your institution’s requirements. A first enquiry can describe the study without participant-level data.

6. What happens after the first report?

Agree milestone dates, who reviews each deliverable, the number or scope of revisions, and how later reviewer requests are handled. Discuss authorship and acknowledgment early. For journals following ICMJE recommendations, authorship depends on meeting all four contribution and accountability criteria; paying for analysis alone does not determine authorship.

Compare two quotations on the same basis

Download the consultant comparison worksheet. Record each provider’s actual answer, the supporting document, and unresolved questions. Leave an unknown answer marked unknown rather than assigning a score that suggests false precision.

For example, a hypothetical quote for “analysis and tables” and another for “data audit, analysis plan, code, tables, and one revision round” describe different packages. Ask both providers to quote the same scope before comparing prices. This example is illustrative; it is not a market-price benchmark.

Questions researchers often ask

How much does a biostatistics consultant cost?

There is no single price that meaningfully describes every study. Request a quotation against an agreed scope, including dataset readiness, analytical complexity, deliverables, deadlines, and revisions. Ask what could trigger additional work and how that would be approved.

Can a consultant guarantee significant results or publication?

Neither is a sound procurement criterion. Statistical findings depend on the data and defensible methods; editorial decisions belong to the journal. Ask how uncertain or inconclusive findings will be explained and reported.

What should I send for an initial discussion?

Send a non-confidential summary of the study question, design, stage, planned outcomes, approximate dataset size, deadline, and outputs you need. Describe available documentation. Agree the data-transfer arrangements before sharing research records.

What if I am planning a study for 2027?

Use the same checklist now, label projected dates as plans, and recheck applicable funder, journal, and institutional requirements before submission. A future-year label is not evidence that a method or service is better.

Discuss the decision you need help with

If StatMedAnalysis is one of the options you are considering, describe your study and the support you need. Ask for the scope, deliverables, and revision arrangements in writing so you can compare them with your other options.
