You’re probably shocked and overwhelmed when your teacher asked you to observe relationships between numeric variables using a scatter plot.

You might be wondering what a scatter plot is. Worry no more! In this article, you will learn how to use it like a pro!

### Scatter Plot – What is it?

Called as a scatter chart or graph, a scatter plot represents values for two numeric variables using dots. The position of all dots on both vertical and horizontal axis show values.

### When to Use a Scatter Plot?

A scatter plot is a flexible chart to use these days. It is not only utilized to observe relationships between numeric variables but also used to identify correlational relationships.

A scatter plot is also the recommended tool when determining patterns in data. To divide data points into different groups, we need to base it on how a set of points cluster with each other.

But wait, there’s more! A scatter plot is useful when you are tasked to segment data into parts like the development of personas.

### Mistakes to Avoid When Using Scatter Plots

Although using scatter plots is easy, it is difficult when you give it a shot. In fact, most people commit these mistakes. Take a close look at the following:

*Overplotting*

Do you have a large number of data points to present in a scatter chart? If yes, the risk of overplotting is higher than you have expected. But it is avoidable. You can sample a subset of data points. Alternatively, you can change the dots to make overlaps visible.

*Misinterpretation of Correlation*

Another problem is when we interpret correlation as causation. Nevertheless, it is not common. Many people usually experience overplotting.

**Bottom Line**

We hope this simple and comprehensive guide will help you use a scatter chart in the future. Enjoy! Share this article to your friends and classmates today!
