## Overview

The Array Analyzer is a powerful utility designed to process and extract key statistical insights from your datasets. Whether you are working with numerical sequences or text lists, this tool provides instant calculations for averages, medians, modes, and frequency distributions to help you understand your data structure at a glance.

## Inputs

- **Input Array** (textarea): Enter array as JSON format: \[3, 1, 2\] or comma-separated values: 3, 1, 2 or one per line
- **Include Frequency Analysis** (checkbox)
- **Sort Frequency by Count (Descending)** (checkbox)
- **Case Sensitive (for strings)** (checkbox)
- **Trim Whitespace (for strings)** (checkbox)
- **Custom Separator (for text input)** (text): Enter separator (default: comma, semicolon, or newline)

## When to use

- When you need to quickly calculate descriptive statistics like mean, median, and range for a list of numbers.
- When you need to identify the frequency of specific items or detect duplicates within a large dataset.
- When you need to clean and normalize raw input data by trimming whitespace or standardizing case sensitivity.

## How it works

- Paste your data into the input field using JSON format, comma-separated values, or one item per line.
- Adjust your preferences, such as enabling frequency analysis or setting a custom separator if your data uses unique delimiters.
- Click the analyze button to generate a comprehensive report containing statistical summaries and item counts.
- Review the output to identify trends, outliers, or data distribution patterns.

## Use cases

- Analyzing survey responses to determine the most frequent answers.
- Validating numerical datasets for outliers or range errors.
- Cleaning and summarizing log file entries or user input lists.

## Frequently asked questions

### What input formats are supported?

The tool supports JSON arrays, comma-separated values, or lists separated by newlines.

### Can I analyze text data?

Yes, the tool handles strings and provides frequency analysis, including options for case sensitivity and whitespace trimming.

### How does the frequency analysis work?

It counts the occurrences of each unique element and can sort them in descending order to show you the most common items.

### Is the analysis case-sensitive?

You can toggle the 'Case Sensitive' option to treat 'Apple' and 'apple' as either the same or distinct items.

### What statistics are provided?

The tool calculates essential metrics including minimum, maximum, average, median, and mode.
