## Overview

The Random Number Generator is a versatile tool designed to produce sequences of numbers based on specific statistical distributions, making it ideal for simulations, testing, and data analysis.

## Inputs

- **Distribution Type** (select)
- **Number of Values** (number): Enter number of values to generate (1-1000)
- **Minimum Value** (number): Enter minimum value
- **Maximum Value** (number): Enter maximum value
- **Mean** (number): Enter mean value
- **Standard Deviation** (number): Enter standard deviation
- **Lambda (λ)** (number): Enter lambda parameter
- **Probability** (number): Enter probability (0-1)

## When to use

- When you need to generate test data for software development or database population.
- When performing statistical simulations that require specific probability distributions.
- When you need a quick, unbiased selection of random integers or floating-point numbers.

## How it works

- Select your preferred statistical distribution type from the dropdown menu.
- Adjust the parameters such as mean, standard deviation, or probability based on your specific requirements.
- Specify the total count of numbers you wish to generate.
- Click generate to instantly produce your sequence of random values.

## Use cases

- Generating synthetic datasets for machine learning model training and validation.
- Creating randomized test cases for software quality assurance and stress testing.
- Simulating probabilistic events for academic research or statistical modeling.

## Frequently asked questions

### What distributions are supported?

The tool supports Uniform, Normal (Gaussian), Exponential, Poisson, Binomial, and Integer distributions.

### Can I generate more than 1000 numbers?

The tool is currently limited to generating up to 1000 values per request to ensure optimal performance.

### Are the numbers truly random?

The tool uses high-quality pseudo-random number generation algorithms suitable for most statistical and testing applications.

### What is the difference between Uniform and Normal distribution?

Uniform distribution ensures every number in a range has an equal chance of appearing, while Normal distribution clusters values around a specified mean.

### Do I need to install any software?

No, this is a web-based utility that runs directly in your browser without requiring any installations.
