The chart that is used to display values for two variables for a set of data is called a Scatter Chart, also known as a Scatter Plot.
A scatter chart is a mathematical diagram that displays numerical data as points on a graph with horizontal and vertical axes. Each point on the graph represents the values of two variables. The x-axis represents one variable and the y-axis represents the other variable.
The scatter chart is used to determine if there is a relationship between the two variables. If there is a positive relationship, the points on the chart will form a diagonal line that slopes upwards from left to right. If there is a negative relationship, the points on the chart will form a diagonal line that slopes downwards from left to right. If there is no relationship, the points will be scattered randomly on the chart.
Scatter charts are commonly used in project management to display data such as the relationship between the duration and cost of a project, or the relationship between the quality and customer satisfaction.
Histograms, on the other hand, are charts that show the frequency distribution of a set of data. Fishbone diagrams, also known as Ishikawa diagrams or cause-and-effect diagrams, are used to identify the root cause of a problem. Gantt charts are used to display the schedule of a project.
