A project manager wants to analyze the relationship between two variables in project data to determine if changes in one variable are associated with changes in the other. Which diagramming tool should the project manager use to visualize this potential correlation?
Fishbone diagram
Scatter diagram
Pareto chart
Histogram
A scatter diagram is used to plot data points for two variables on a coordinate plane, allowing the project manager to observe any patterns or relationships between them. By visualizing the data, it's easier to identify whether an increase or decrease in one variable corresponds with changes in the other, indicating a potential correlation. Histograms display the distribution of a single variable, Pareto charts highlight the most significant factors in a dataset, and fishbone diagrams help identify root causes of a problem. These tools do not effectively show the relationship between two variables like a scatter diagram does.
