Microsoft Excel and other software packages can do the computations needed to create the diagram. Scatter Diagram ExamplesĪ background in statistics is not required to use scatter diagrams. Scatter graphs visually show the correlation between two variables. Additionally, being able to interpret scatter diagrams for the PMP exam enhances overall project management skillsets for work settings. Correlation is a relationship in bivariate data. The Project Management Institute® (PMI) provides a PMP exam reference list although there is not a specific scatter diagram example for the PMP exam, a general understanding of this tool is expected. Positive correlation means as one variable increases, so does the other. Scenario questions may require the future PMP holder to interpret data in scatter diagrams or select the best quality tool to use in a specific situation. Graphs can either have positive correlation, negative correlation or no correlation. listing the Seven Quality Tools, including scatter diagrams.This relationship can be between twos causes, or a cause and an effect, etc. Scatter diagrams are useful to determine the relatedness between two actual. To understand how scatter diagrams work, consider the following example. It could be the relationship between a cause and an effect, between one cause and another, or even between one cause and two others. This relationship cans be between two causes, or a cause and an effect, etc. A scatter diagram is used to show the relationship between two kinds of data. recognizing a visual depiction of the relationship between two variables Scatter diagrams what useful to determine who relationship within two variables.knowing the definition of the term (6 th edition of the PMBOK® Guide),.(The data is plotted on the graph as 'Cartesian (x,y) Coordinates') Example: The local ice cream shop keeps track of how much ice cream they sell versus the noon temperature on that day. In this example, each dot shows one person's weight versus their height. For the PMP exam, project managers should know about scatter diagrams, including: A Scatter (XY) Plot has points that show the relationship between two sets of data. It is important to know what scatter diagrams are in PMP terms as part of the exam preparation process.

to determine whether two effects that appear to be related both occur with the same cause.Īs a quality control tool, scatter diagrams can help the PMP holder with identifying correlations between variables, thus advising process and resource decisions.

to determine objectively whether a particular cause and effect are related, or.

Plotting the variables on a scatter diagram is a systematic way to view the relationship between the variables and see if its a. Scatter Plot for Positive Correlation Scatter Plot for Negative Correlation Scatter Plot for Null Correlation.

to identify potential root causes of problems, Based on the correlation, scatter plots can be classified as follows.

The American Society for Quality (ASQ) provides these potential uses for the scatter diagram when determining if two variables are related: Determining a correlation between variables can enable better decisions for the project.
