What is a Scatter Plot?
Scatter plot is one of the most important data visualization techniques and it is considered one of the Seven Basic Tools of Quality. A scatter plot is used to plot the relationship between two variables, on a two-dimensional graph that is known as Cartesian Plane on mathematical grounds.
It is generally used to plot the relationship between one independent variable and one dependent variable, where an independent variable is plotted on the x-axis and a dependent variable is plotted on the y-axis so that you can visualize the effect of the independent variable on the dependent variable. These plots are known as Scatter Plot Graph or Scatter Diagram.
Applications of Scatter Plot
As already mentioned, a scatter plot is a very useful data visualization technique. A few applications of Scatter Plots are listed below.
- Correlation Analysis: Scatter plot is useful in the investigation of the correlation between two different variables. It can be used to find out whether two variables have a positive correlation, negative correlation or no correlation.
- Outlier Detection: Outliers are data points, which are different from the rest of the data set. A Scatter Plot is used to bring out these outliers on the surface.
- Cluster Identification: In some cases, scatter plots can help identify clusters or groups within the data.
Scatter Plot
Scatter plot is a mathematical technique that is used to represent data. Scatter plot also called a Scatter Graph, or Scatter Chart uses dots to describe two different numeric variables. The position of each dot on the horizontal and vertical axis indicates values for an individual data point.
In this article, we have covered the definition of a Scatter Plot, Scatter Plot Graph, How to Construct a Scatter Plot, and others in detail.
