Sturges’ Rule Calculator - Savvy Calculator

Introduction

Sturges’ Rule is a widely used method for determining the number of bins in a histogram or bar chart when visualizing data. This HTML-based Sturges’ Rule Calculator simplifies the process, making it easy to calculate the ideal number of bins for your dataset. In this guide, we will walk you through how to use, understand the formula behind it, provide an example solve, answer common questions, and offer a complete HTML code with a clickable button for your convenience.

How to Use

To use the Sturges’ Rule Calculator, follow these steps:

Create an HTML document with a <form> element.
Add an input field for the sample size (n) and a submit button.
Insert a JavaScript <script> to handle the calculation.
When the user submits the form, the calculator will display the recommended number of bins based on Sturges’ Rule.

Formula

Sturges’ Rule calculates the number of bins (k) for a histogram using the formula:

$k = 1 + 3.322 \cdot log_{10} (n)$

Where:

$k$ is the number of bins.
$n$ is the sample size.

Example

Suppose you have a dataset with a sample size ( $n$ ) of 200. Using Sturges’ Rule, the calculation would be as follows:

$k = 1 + 3.322 \cdot log_{10} (200)$ $k = 1 + 3.322 \cdot 2.3010$ $k = 1 + 7.629$ $k \approx 8.629$

Rounded to the nearest whole number, $k$ is approximately 9. So, you should use 9 bins for your histogram.

FAQs
