# How To Create A Normal Distribution Curve In Excel

Creating a normal distribution curve is a common statistical task that can be accomplished using Excel. This process involves organizing your data set and utilizing Excel's chart features to craft the visualization.

Understanding the steps of generating a normal distribution curve in Excel can aid in data analysis and decision-making. However, there may be simpler tools for this task.

Throughout this guide, we'll explore how Sourcetable offers a more streamlined experience for crafting normal distribution curves compared to the traditional Excel method.

## Creating a Normal Distribution Curve in Excel

### Introduction to Bell Curve in Excel

Excel enables the creation of a bell curve, a graphic representation of a normal distribution of data, using its built-in Analysis ToolPak. These normally distributed datasets can model various phenomena, such as employee performance and exam evaluations.

### Generate Random Numbers

Initiate the process by using the Random Number Generation tool within the Analysis ToolPak. This tool creates a set of random numbers derived from your data, serving as the foundation for the bell curve.

### Create Histogram

Employ the Histogram tool from the Analysis ToolPak to convert the random numbers into a histogram. This frequency distribution will visually prepare the data for its transformation into a bell curve.

### Chart Formation

Transform the histogram into a bell curve chart. This visual representation categorizes dataset values into percentiles, placing higher values on the right, lower values on the left, and the bulk around the mean, representing the average score.

### Performance and Mean Score Analysis

Strategically use the bell curve to evaluate performance, compare marks, and calculate data point percentiles. The mean score dictates the curveās center, while standard deviation measures data variance. Utilizing the 68.2%, 95.5%, and 99.7% distribution rules within one, two, and three standard deviations from the mean respectively, aids in in-depth analysis.

The NORMDIST function, though replaced by newer, accurate functions like NORM.DIST and NORMSDIST, serves statistical applications including hypothesis testing. The NORMSDIST specifically calculates the standard normal distribution when cumulative equals TRUE.

## Common Use Cases

• Assessing the performance of a group of students on an exam

• Evaluating the distribution of employee salaries within a company

• Analyzing customer purchasing behaviors over a set period

• Measuring the consistency of a manufacturing process

• Forecasting expected returns for a financial portfolio

## Excel vs Sourcetable: Data Management and Reporting Compared

Excel, a Microsoft-developed spreadsheet tool, excels in data analysis, budgeting, and data manipulation tasks, but lacks native data source connectivity, making Sourcetable a superior choice for modern data integration. Sourcetable syncs seamlessly with over 100 applications, facilitating real-time data queries and automatic live model updates without requiring coding skills.

Sourcetable's spreadsheet-like interface is both familiar to Excel users and more accessible, offering a contemporary approach to spreadsheet applications. With data synchronization every 15 to 5 minutes and collaborative features, Sourcetable streamlines business operations for growth teams by centralizing data analysis, making it more efficient than Excel.

While Excel necessitates add-ons for extended functionality, Sourcetable comes equipped with an AI copilot that simplifies complex tasks through a conversational chat interface. The AI assists in formulating calculations and leveraging templates, enhancing user experience and reducing the need for deep technical expertise.

Cost-wise, Sourcetable offers a 14-day free trial, after which plans start at \$50/month for the basic starter package and \$250/month for the pro version. Excel, on the other hand, requires a purchase or an Office 365 subscription, and while it provides robust analysis and calculation capabilities, its sharing and collaboration features are more traditional compared to Sourcetable's integrated, real-time collaboration environment.
