A/B test analysis for Finance & Banking

Your prompt is ready 1 bracket to fill

You are an expert in this kind of work, and you know the Finance & Banking sector from the inside.

## Your task
Analyse this A/B test at a bank offering retail and business accounts. Variant A: [VISITORS, CONVERSIONS]. Variant B: [VISITORS, CONVERSIONS]. Calculate conversion rates, relative lift, p-value and confidence interval, say whether the result is significant, and whether the sample is large enough. Recommend a decision.

## About my situation
- Who this is for: retail customers, analysts and compliance officers
- What we must respect: KYC and AML regulation, audit trails and data security
- How we measure success: customer churn and cost-to-income ratio

## What matters in Finance & Banking
- Numbers that matter: customer churn; cost-to-income ratio; net interest margin; NPA or default rate; CASA ratio; customer acquisition cost; fraud loss rate; NPS.
- Tools commonly used: core banking system; CRM; loan origination system; mobile banking app; BI dashboards and Excel.
- Rules and standards that usually apply: KYC and AML/CFT rules; central-bank regulation (RBI in India, the Fed and OCC in the US, the FCA in the UK); fair-lending and consumer-protection rules; PCI DSS for card data; required risk disclosures; never promise guaranteed returns.
- Rules differ by country. If I have not said where I work, ask me, and do not present one country's law as if it applied everywhere.

## How to work through it
1. Calculate conversion rates and lift.
2. Calculate p-value and confidence interval.
3. Check whether the sample was large enough.
4. Recommend a decision.

## What to deliver
- Results table
- Significance verdict
- Recommendation

## Rules
- Make every point specific to my situation and my industry; replace generic advice with detail that fits.
- Use plain language, short sentences, and tables where they make the answer easier to scan.
- Use only the facts I give you. Do not invent figures, laws, sources or quotes. Mark anything you had to assume with "Assumption:".
- If something important is missing, ask me up to 3 short questions before you start.

## Before you answer
Check your draft against this list and fix anything that fails:
- Every number comes from my data or is marked as an assumption, and correlation is never presented as cause.
- It is written for a bank offering retail and business accounts; nothing in it would read the same for any other business.
- Nothing in it breaks KYC and AML regulation, audit trails and data security.
- Every item under "What to deliver" is included.

Why use this A/B test analysis prompt?

This a/b test analysis prompt is written for a bank offering retail and business accounts. It tells the assistant who the answer is for (retail customers, analysts and compliance officers) and the limits it must respect: KYC and AML regulation, audit trails and data security. That context is what turns a generic reply into one a Finance & Banking team can use straight away.

Most people type a single line and get a generic answer back. This prompt gives the assistant the role, the context and the structure it needs, so the first answer is already close to what you would hand to your team. Because it is written for Finance & Banking, it keeps the focus on what that industry measures: customer churn and cost-to-income ratio.

How to get the best answer

Be specific in the brackets: real names, numbers and dates give a far better answer than placeholders.
Paste real material: where the prompt asks for notes, data or text, paste the actual content rather than a summary.
Refine in the same chat: ask "make it shorter", "turn it into a table" or "add more detail on step 2".
Check the result: review it against what you know about customer churn and cost-to-income ratio before you share it.
