What is Scatter Diagram (Plot) in Project Management?

In project management, you may need to see repeated regular behaviors of things or you may want to see the direction that something is changing and use them to determine the amount of effort and resources that need to be allocated to ensure successful outcomes. 

A scatter plot is an effective tool to display two sets of variables; the former is represented on the x-axis, while the latter is mapped on the y-axis. All data points are indicated on the chart, unveiling the relationship between them. By studying the placements of the points, it is possible to reveal trends between them.

After inputting the data onto a scatter graph, one can recognize the connection between the hours dedicated to a project and the success it has yielded. The x-axis stands for the allocated time while the y-axis reflects the success rate. 

When to Use?

It is recommended to be used especially when you need to find some peculiar points in the data that you have obtained. These types of data potentially compromise the results of the analysis.  Scatter diagrams are useful here. Being able to recognize any unusual data points is essential to guarantee that the data is accurate and trustworthy.

Graphically illustrating data through scatter diagrams allows project managers to detect patterns and trends more quickly and easily than simply viewing the data in tabular form. This type of visualization simplifies complicated data, allowing a deeper comprehension of the information.
