Perform sample size calculation

Automates✓ Available Now

What You Do Today

Estimate required sample size based on effect size, variability, power, alpha — account for dropout, interim analyses, adaptive design elements

AI That Applies

AI simulates thousands of trial scenarios to optimize sample size under various assumptions about effect size, dropout rates, and enrollment patterns

Technologies

How It Works

For perform sample size calculation, the system draws on the relevant operational data and applies the appropriate analytical models. The simulation engine runs thousands of scenarios by varying each uncertain input across its probability range, building a distribution of outcomes that quantifies the risk. The results integrate into the practitioner's existing workflow — presenting recommendations, flags, or automated outputs alongside their normal working context.

What Changes

Simulation-based sample sizing runs thousands of scenarios automatically instead of manual sensitivity tables; identifies the most efficient design

What Stays

You choose the assumptions, interpret regulatory acceptability of adaptive designs, and defend the sample size rationale to FDA

What To Do Next

This section won't tell you what your numbers should be. It will show you how to find them yourself. Every instruction below produces a real, verifiable result in your organization. No benchmarks, no projections — just the steps to build your own evidence.

1

Establish Your Baseline

Know where you are before you move

Before adopting AI tools for perform sample size calculation, understand your current state.

•
Map your current process: Document how perform sample size calculation works today — who does what, how long it takes, where the bottlenecks are. You need this baseline to measure improvement.
•
Identify the judgment points: You choose the assumptions, interpret regulatory acceptability of adaptive designs, and defend the sample size rationale to FDA. These are the boundaries AI won't cross.
•
Assess your data readiness: AI tools for this area need data to work. Check whether your organization has the historical data, integrations, and data quality to support EAST tools.

Without a baseline, you can't measure whether AI actually improved anything. You'll adopt tools without knowing if they're working.

Define Your Measures

What to track and how to calculate it

Time per cycle

How to calculate

Measure how long perform sample size calculation takes end-to-end today, then after AI adoption.

Why it matters

The most visible improvement is speed. If AI doesn't save time, question whether it's adding value.

Quality of output

How to calculate

Track error rates, rework frequency, or stakeholder satisfaction scores before and after.

Why it matters

Speed without quality is just faster mistakes. Measure both.

When to check: Check after 30 days of consistent use, then quarterly.
The commitment: Give new tools at least 30 days before judging. The first week is always awkward.
What NOT to measure: Don't measure AI adoption rate as a KPI. Adoption follows value — if the tool helps, people use it.

Start These Conversations

Who to talk to and what to ask

your data engineering lead

“What data do we already have that could improve how we handle perform sample size calculation?”

They control the data pipelines that feed your analysis

your VP or director of analytics

“Who on our team has the deepest experience with perform sample size calculation, and what tools are they already using?”

They're deciding the team's AI tool adoption strategy

your data governance lead

“If we brought in AI tools for perform sample size calculation, what would we measure before and after to know it actually helped?”

AI-generated insights need the same quality standards as manual analysis
