When one variable (dependent variable) increase as the other variable (independent variable) increases, there is a positive correlation. Height and clothes size is a good example here. In the above text, we many times mentioned the relationship between 2 variables. When just want to visualize the correlation between 2 large datasets without regard to time.When working with root cause analysis tools to identify the potential for problems.When trying to find out whether there is a relationship between 2 variables.Scatter diagram has many applications and usages nowadays. To help you predict the behavior of one variable (dependent) based on the measure of the other variable (independent).To show how much one variable affects another – the main purpose!.To show whether 2 variables are related or not.In today world of data science, Scatter graphs have a couple of purposes. So, What is The Purpose of a Scatter Plot? The second variable is called dependent because its values depend on the first variable.īut it is also possible to have no relationship between 2 variables at all. Usually, when there is a relationship between 2 variables, the first one is called independent. This line is used to help us make predictions that are based on past data.

The purpose is to show how much one variable affects another.Ī classic example is the relationship between monthly sales and advertising dollars in a company. It is an X-Y diagram that shows a relationship between two variables. It is used to plot data points on a vertical and a horizontal axis. Types of correlation in a scatter plot.Scatter plot helps in many areas of today world – business, biology, social statistics, data science and etc. The scatter plot has also other names such as scatter diagram, scatter graph, and correlation chart. If you are wondering what does a scatter plot show, the answer is more simple than you might think.
