Draw a Bell Curve
A bell curve is a statistical graphic that shows a standard normal distribution. It shows that some features tend to have more cases in a middle range instead of a lower or higher range. Here's a tutorial on how to draw it!
Steps
- Draw two perpendicular lines forming an axis.
- Name them according to your research/results.
- Add a scale. The example goes from 55 to 145 in increments of 15 points, but it can be however you'd like.
- Represent the results of your research with lines.
- In the example you can see that most people have a feature value of 100.
- Draw a curved line intersecting each tip of the lines you just drew. This is the bell-like shape that gives this graph its name.
- Color it. Use different colors for the different ranges.
Tips
- If you want to use a bell curve for a presentation for work or school, you should probably create it using a computer. Try using MS Paint or even just go on Excel and put in your information so it can make the graph for you. The more professional your image looks, the more professional you'll seem
