1. What is a Histogram chart?
A Histogram chart shows the distribution of a numeric variable's values in the form of column called bin or class.
When to use Histogram chart?
A Histogram chart is recommended when you:
Have continuous measurements and want to understand the distribution of values and look for output.
Summarize large data sets graphically.
Analyze the data distribution (especially when determining whether the output is distributed approximately normally)
Conduct a segmentation analysis (might be helpful in decision-making)
2. How to build a Histogram chart with example
The Histogram chart is an effective way to visualize the distribution of unit prices, providing a visual representation of the frequency or count of unit price ranges or intervals, enabling businesses to analyze the price distribution patterns, identify common price ranges or outliers, and gain insights into the pricing dynamics of a specific product or market segment.
