Bell Curve Chart

Also known as Normal Distribution Curve

1. What is a Bell Curve chart?

A Bell Curve is used to display data distribution across a specified group. Its peak is always at the center, and data goes down on either side of the curve.

When to use Bell Curve chart?

A Bell Curve (normal distributions) is used commonly in statistics, including in analyzing economic and financial data. This type of visualization is also used for the display of continuous distribution with a single variable.

2. How to build a Bell Curve chart with example

The Bell Curve chart, also known as a Gaussian distribution chart, is a powerful tool for analyzing the distribution of unit prices. By plotting unit prices along the horizontal axis and the frequency or count on the vertical axis, the Bell Curve chart provides a visual representation of how unit prices are distributed, allowing businesses to understand the central tendency, variability, and outliers in the price data, facilitating informed pricing strategies and decision-making based on a comprehensive understanding of the price distribution.
