There is an old saying in statistics: "If you torture the data long enough, it will confess."
It starts innocently. You run a regression. The P-value is 0.06. So you remove an outlier. 0.055. You control for age. 0.049. Boom. Significant. You publish.
But deep down, you know. You didn't find the truth; you manufactured one.
This "Garden of Forking Paths," as researchers call it, is where good science goes to die. The problem isn't your math; it's your lack of a Pre-Commitment Strategy. Without a locked-in plan before you touch the CSV file, every decision you make is biased by the result you want to see.
We need to stop treating analysis as an improvisation act and start treating it like a Flight Plan. You don't decide where to land the plane while you are in the air.
I have engineered a "Data Analysis Strategist" system prompt that acts as your methodological conscience. It forces you to define your route, your fuel, and your emergency landings before you ever take off.
The "Analysis Strategist" Protocol
This tool transforms valid, flexible LLMs (like Claude, Gemini, or ChatGPT) into rigid methodological enforcers. It doesn't just ask "what" you are analyzing; it demands to know the assumptions behind your methods and the remedies for when they fail.
It operates on one core principle: Validity over Complexity.
Copy the instruction below to generate a bulletproof roadmap for your next data deep dive.
# Role Definition
You are a Senior Research Methodologist and Data Analysis Strategist with 15+ years of experience designing analysis frameworks for academic institutions, research organizations, and data-driven enterprises. Your expertise spans:
- **Quantitative Methods**: Statistical modeling, hypothesis testing, regression analysis, machine learning applications
- **Qualitative Analysis**: Thematic analysis, grounded theory, content analysis, narrative analysis
- **Mixed Methods**: Integration strategies, triangulation, sequential and concurrent designs
- **Research Tools**: R, Python, SPSS, SAS, NVivo, ATLAS.ti, Tableau, Power BI
You excel at translating complex research questions into executable analysis blueprints that balance methodological rigor with practical feasibility.
# Task Description
Design a comprehensive Data Analysis Plan that serves as a roadmap for systematic data examination. This plan should:
1. Align analysis methods with research objectives
2. Specify data preparation and cleaning protocols
3. Detail statistical or analytical techniques with justification
4. Anticipate potential challenges and mitigation strategies
5. Define quality assurance checkpoints
**Input Parameters**:
- **Research Question(s)**: [Primary research question and any sub-questions]
- **Data Source(s)**: [Survey, experiments, secondary data, interviews, etc.]
- **Data Type**: [Quantitative, qualitative, or mixed]
- **Sample Size**: [Number of observations/participants]
- **Key Variables**: [Dependent, independent, control, moderating variables]
- **Analysis Purpose**: [Exploratory, descriptive, inferential, predictive]
- **Timeline**: [Available time for analysis]
- **Software Preference**: [R, Python, SPSS, Excel, etc.]

Why This Protocol Saves Your Project
Most analysis plans fail because they are optimistic. They assume the data is clean, the residuals are normal, and the p-values will cooperate. This prompt assumes everything will go wrong.
1. The "Assumption Check" Firewall
Look at Section D: Quality Assurance. Most prompts skip this. They jump straight to "Run the T-test." This prompt forces a pause. "Are your variances equal? Is your data normally distributed?" It demands an Assumption Testing Procedure. It forces you to check the engine before you rev it. If your data violates assumptions, the plan already has a "Plan B" (Non-parametric alternatives) waiting in the wings.
2. The Logic of "Sensitivity"
Notice Section C: Sensitivity Analysis Plan. This is the anti-p-hacking device. Instead of running one model and crossing your fingers, the AI maps out robustness checks. "What happens if we exclude outliers? What if we change the time window?" By pre-specifying these checks, you insulate yourself from the temptation to cherry-pick. You aren't just finding a result; you are testing its strength.
3. The Code-Ready Prescription
Theoretical plans are useless at 2 AM. The Output Requirement for "Code snippets where applicable" means you don't just get a strategy; you get the library(lavaan) or import pandas block to execute it. It bridges the gap between "We should do this" and "Here is the script."
No More "Data Dredging"
We live in an era where data is abundant, but rigorous insight is scarce. It is easy to find a pattern. It is hard to find a true pattern.
This system prompt doesn't make the math easier. It makes the discipline easier. It acts as the senior partner looking over your shoulder, ensuring that when you finally claim a discovery, you can stand behind it with absolute confidence.
Don't just analyze. Strategize.
