📖 How to Use
🎯 Getting Started
Paste or type your dataset (numbers separated by spaces, commas, or newlines):
- Automatic Analysis: Statistics update in real-time as you type
- Multiple Formats: Accepts comma-separated (1,2,3), space-separated (1 2 3), or line-separated values
- Data Cleaning: Automatically ignores non-numeric values and empty lines
- Instant Visualization: Histogram and box plot generate automatically
📐 Statistical Measures
The dashboard calculates five core descriptive statistics:
- Mean: Average value (sum of all values ÷ count)
- Median: Middle value when sorted (50th percentile)
- Mode: Most frequently occurring value(s)
- Standard Deviation: Measure of spread from the mean (σ)
- Variance: Average squared deviation from mean (σ²)
💡 Additional metrics: Min, Max, Range, Q1, Q3, IQR (Interquartile Range)
📊 Visualizations
Histogram: Shows distribution of data across bins (frequency chart)
- Automatically calculates optimal bin count using Sturge's Rule
- Height shows frequency (how many values fall in each range)
- Helps identify normal distribution, skewness, and outliers
Box Plot: Shows five-number summary and spread
- Center line: Median (Q2)
- Box edges: Q1 (25th percentile) and Q3 (75th percentile)
- Whiskers: Minimum and Maximum values
- Visualizes data concentration and outliers
💾 Export Options
Transfer your calculated results to spreadsheet software:
- Copy to CSV: Copies formatted data to clipboard, ready to paste into Excel, Google Sheets, or any spreadsheet
- Format: Includes dataset, statistics, and calculated values in rows for easy pasting
- Workflow: Calculate stats here → Copy to CSV → Paste into assignment spreadsheet
💡 Perfect for statistics coursework requiring spreadsheet software
