## Overview

The Frequency Distribution Generator allows you to quickly organize raw datasets into structured frequency tables, enabling deeper statistical insights and easier data visualization preparation.

## Inputs

- **Data Input** (textarea): Enter your CSV data (first row should contain headers)...
- **CSV Delimiter** (select)
- **Group By Column** (text): Enter column name to group by (leave empty for all data)
- **Bin Type** (select)
- **Number of Bins** (number): Enter number of bins (1-100)
- **Bin Width** (number): Enter bin width (integer)
- **Custom Bin Ranges** (textarea): Format: "min-max" or "value" for single value bins
- **Output Format** (select)
- **Include Percentages** (checkbox): Show percentage of total for each category
- **Include Cumulative Totals** (checkbox): Show cumulative frequency distribution
- **Sort By** (select)
- **Sort Direction** (select)
- **Trim Cell Values** (checkbox): Remove whitespace from beginning and end of cell values
- **Include Empty Values** (checkbox): Include empty cells in frequency count

## When to use

- When you need to summarize large datasets into meaningful numeric groups or bins.
- When preparing data for histograms or statistical reporting to identify trends and patterns.
- When you need to calculate percentage distributions or cumulative totals from raw CSV data.

## How it works

- Paste your raw CSV data into the input area and select the appropriate delimiter.
- Choose a binning method such as automatic detection, fixed width, or custom ranges to define your data groups.
- Configure additional settings like percentage inclusion, sorting preferences, and cumulative totals.
- Generate your frequency table in your preferred output format, including Markdown, JSON, or a formatted table.

## Use cases

- Summarizing customer age demographics into specific age brackets for marketing reports.
- Analyzing test score distributions by grouping numeric results into fixed-width grade ranges.
- Converting raw transaction logs into frequency counts to identify high-volume product categories.

## Frequently asked questions

### What input formats are supported?

The tool accepts raw CSV data. You can specify the delimiter used in your data, such as commas, tabs, pipes, or spaces.

### Can I define my own bin ranges?

Yes, by selecting the 'Custom Ranges' bin type, you can manually define specific intervals (e.g., '0-10', '10-20') to group your data exactly as needed.

### Does the tool calculate percentages?

Yes, you can enable the 'Include Percentages' checkbox to automatically calculate the percentage of the total for each category.

### How do I handle empty cells in my data?

The tool includes an 'Include Empty Values' option, which allows you to decide whether to count empty cells as a separate category in your distribution.

### What output formats are available?

You can export your results as a formatted table, Markdown table, JSON array, or raw CSV format.
