Data Analysis Prompts
Trend Analysis
[System] You are a senior data analyst.
[Task] Identify key trends in this dataset.
[Context] Data: {paste_data_or_describe}. Time period: {period}. Business context: {what_we_measure_and_why}.
[Output] 5 key trends, each with: the finding (1 sentence), supporting data (specific numbers), significance (why it matters), and recommended action. Rate each trend's confidence: High/Medium/Low.SQL Query Builder
[System] You are a database expert with expertise in {PostgreSQL/MySQL/BigQuery}.
[Task] Write a SQL query to {requirement}.
[Context] Schema: {table_descriptions}. Expected data volume: {rows}. Performance requirement: {speed}.
[Output] Optimized query with comments explaining each section. Include: index recommendations, estimated execution time, and alternative approaches if the data is large.Executive Dashboard
[System] You are a business intelligence specialist.
[Task] Create an executive dashboard summary from this data.
[Context] KPIs: {list}. Data: {paste_metrics}. Reporting period: {period}. Audience: {C-suite/board}.
[Output] Dashboard with: 5 headline metrics (RAG status), 3 trend charts (describe), key insight per metric, and 2 recommended actions. Under 1 page.Anomaly Detection
[System] You are a data scientist specialising in anomaly detection.
[Task] Identify unusual patterns in this data.
[Context] Data: {paste_data}. Normal range: {expected_values}. Business impact of anomalies: {impact}.
[Output] List anomalies with: timestamp/location, severity (Critical/Warning/Info), possible causes, and investigation steps. Sort by severity.Forecasting
[System] You are a quantitative analyst.
[Task] Forecast {metric} for the next {period}.
[Context] Historical data: {paste_data}. Known upcoming factors: {events/seasonality}. Business context: {growth_targets}.
[Output] Forecast with confidence intervals (optimistic/base/pessimistic). State all assumptions. Note limitations. Include "what would need to be true" for each scenario.Data Cleaning
[System] You are a data engineer.
[Task] Write a data cleaning pipeline for this dataset.
[Context] Raw data sample: {paste_sample}. Known issues: {nulls/duplicates/format_issues}. Target format: {schema}.
[Output] Python/pandas code with comments. Handle: missing values, duplicates, type conversion, outliers, and standardisation. Include data quality report after cleaning.Best AI Tools for Data Analysis

Frequently Asked Questions
Can ChatGPT analyse data?
Yes. ChatGPT (GPT-4o) can analyse CSV files, write SQL queries, create charts, identify trends, and generate executive summaries. For best results, upload your data file and use a structured STCO prompt specifying what insights you need.
Which AI is best for data analysis?
Google Gemini 2.0 with its 2M token context window is best for large datasets. ChatGPT with Code Interpreter is best for interactive analysis with charts. Claude 4 is best for structured analysis of reports and documents. Use STCO prompts with any model for professional results.
Is AI data analysis accurate?
AI data analysis is highly accurate for calculations and pattern recognition. The risks are: misinterpreting causation vs correlation, and hallucinating trends in noisy data. Always use STCO Output constraints like "state confidence levels" and "distinguish correlation from causation."
Can AI replace data analysts?
No. AI automates the mechanical parts (SQL queries, chart generation, basic trend spotting) but cannot replace business context, strategic thinking, and domain expertise. Analysts using AI are 3-5x more productive.

Output tokens are significantly more expensive than input tokens.
GPT-4o charges $15.00/MTok for output vs $5.00/MTok for input — a 3x premium. Constraining max_tokens from 4096 to 500 saves $11.25 per million requests.
Without output length constraints, LLMs generate verbose responses that consume the most expensive billing vector — output tokens — at 3x the input rate.
OpenAI, 'API Pricing' page, updated 2024API cost predictability allows for fixed pricing models.
Constraining max_tokens and enforcing output schemas reduces per-user cost variance from 300% to 15%, enabling predictable SaaS margins of 70%+.
Without cost controls, a single power user can consume 50x the average API budget, destroying unit economics.
Andreessen Horowitz, 'Who Owns the Generative AI Platform?' analysis, 2023Prompt caching reduces static context costs.
Cached prompt tokens cost $0.30/MTok vs $3.00/MTok uncached on Claude 3.5 Sonnet — a 90% reduction on repeated system instructions.
Without prompt caching, enterprise pipelines re-tokenise and re-bill the same system prompt across thousands of requests, paying 10x more for identical static context.
