Software Testing

Answer: A histogram
Solution: Scatter Plot Diagram: It is used to represent the relationship between variables those are related to the same event.
Cause and effect: It is a black box technique that is used for graphical representation of the given outcome by the system.
Pareto diagram: Pareto diagram is also known as 80-20 rule. It is used to define the 80% of your work will be completed in 20% of the time and 20% of your work will need the remaining 80% of your time.
Histogram: Histogram diagram is also known as bar chart because it uses different size of bars to represent the data or value in graphical form.
So, we use histogram diagram to represent the software defect reports on the basis of different categories of defect.
Therefore, Histogram is the correct answer.
