Final answer:
The chart described is known as a Pareto chart, which is used in quality control programs to visually prioritize issues by displaying bars in descending order. This helps identify the most significant factors to focus on.
Step-by-step explanation:
The specific type of bar charts used in quality control programs by businesses to display the cause of problems graphically is known as D. Pareto charts. A Pareto chart is a graphical tool that represents the causes of a specific event or problem. It is characterized by bars displayed in descending order of frequency or size of the impact, which helps to identify the most significant factors. Pareto charts are beneficial because they visually prioritize what requires focus based on the Pareto principle, also known as the 80/20 rule.
Bar graphs in general are used to compare quantities and can show relationships between different data points, such as population sizes of multiple countries. This type of comparison is useful in various contexts, allowing for a clear visualization of data where we can easily interpret and make decisions.
