SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Analyze structured datasets to quickly derive descriptive statistics and identify patterns, helping you turn raw data into evidence-based decisions.

Core Features & Use Cases

  • Compute descriptive statistics (mean, median, mode, std dev, min, max, percentiles) for numeric columns
  • Identify correlations and trends across variables, including time-series analysis if present
  • Detect anomalies and flag data quality issues, with support for grouping/segmentation
  • Generate concise, evidence-backed findings reports suitable for stakeholders

Quick Start

Provide a descriptive statistics report for the dataset located at the path given in ARGUMENTS.

Frequently Asked Questions about data-analysis

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I compute descriptive statistics for a CSV dataset?

Compute descriptive statistics for a CSV dataset by loading the file and calculating mean, median, mode, standard deviation, min, max, and percentiles. The tool validates the schema and outputs a clear Markdown report containing all numeric column metrics.

Can I run hypothesis testing and correlation analysis on database exports?

Hypothesis testing and correlation analysis are supported for database exports. The tool identifies correlations and trends across variables, optionally runs basic hypothesis tests, and flags data quality issues or anomalies within the structured dataset.

What is the best way to detect anomalies in time-series data?

Detecting anomalies in time-series data is handled by applying descriptive statistics and pattern identification to the loaded dataset. The tool flags data quality issues and outputs evidence-backed findings suitable for stakeholder reporting.

Does this data analysis tool work with TSV files and categorical data?

TSV files and categorical data are fully supported for analysis. The tool validates the presence and schema of the loaded dataset, computes statistics across numeric, categorical, and time-series data, and supports grouping or segmentation.

How do I generate an insights report from raw structured data?

Generate an insights report from raw structured data by loading the dataset and computing descriptive statistics, correlations, and patterns. The tool automatically produces a concise, evidence-backed Markdown report suitable for stakeholders.

What are the limitations of using basic hypothesis tests for data processing?

Basic hypothesis tests are limited to standard statistical validation on structured datasets like CSVs and TSVs. The tool focuses on descriptive statistics, correlations, and pattern identification rather than advanced predictive modeling or machine learning algorithms.
