To increase readability, you can also draw a line through the middle of the graph to demonstrate a positive or negative correlation. The use of dots makes scatter plots easier to read. Many statistical graphs only allow you to record and interpret linear data, while scatter plots can display curved or irregular data points. Scatter plots allow you to compare two seemingly unrelated variables and determine the relationship between them. Scatter plots can offer the following advantages: Read more: Positive and Negative Correlations (With Definitions and Examples) Advantages of scatter plots For example, a study might find that a person's eating habits have no connection to their educational level. No correlation: If there's no visible relationship between the two variables you're analyzing, then they don't correlate. For example, data points might show that the less sleep a person gets each night, the more time they spend feeling tired each day. Negative correlation: A negative correlation occurs when one variable increases as the other decreases in value. For example, a link between a person's age and income might indicate a positive correlation. Positive correlation: If one variable increases equally to another variable, it's usually a positive correlation. You can evaluate the relationship between the variables with the following types of correlation: Whether you use a written or computer-generated scatter plot, you can use this type of graph to learn how one variable correlates with another.
