1. What Is a Histogram?

A histogram is a graphical representation of the distribution of numerical data. It divides the data into bins (intervals) and shows the frequency of values in each bin using vertical bars.

2. How to Use This Calculator

Steps:

1. Enter your numerical data, separated by commas
2. Specify the number of bins (bars) you want in the histogram
3. Add a title and labels for the axes
4. Click "Generate Histogram" to create your graph

3. Interpreting Histograms

Key Features:

• Shape: Look for symmetry, skewness, or multiple peaks
• Center: Where most of the data falls
• Spread: How variable the data is
• Outliers: Unusual values separated from the main pattern

4. Applications of Histograms

Histograms are widely used in:

• Statistics and data analysis
• Quality control and process improvement
• Scientific research
• Business intelligence
• Educational settings

5. Frequently Asked Questions (FAQ)

Q1: How many bins should I use?
A: Generally 5-20 bins work well. Too few bins oversimplify; too many make the pattern hard to see.

Q2: What's the difference between a histogram and a bar chart?
A: Histograms show distribution of continuous data, while bar charts compare discrete categories.

Q3: Can I use this for large datasets?
A: Yes, but very large datasets may require more bins to show the distribution clearly.

Q4: Why is my histogram empty or not showing properly?
A: Check that your data contains only numbers separated by commas, with no text or invalid characters.

Q5: Can I download the histogram?
A: Yes, you can right-click on the graph and select "Save image as" to download it.
