AI Explanation

To answer this question, you need to understand the different types of charts used to display data.

Option A) Run chart - This option is incorrect. A run chart is used to display data over time to identify trends, patterns, or shifts in a process.

Option B) Histogram - This option is correct. A histogram is a bar chart that displays the frequencies or counts of measured data. It is used to show the distribution or spread of data and identify any outliers or unusual patterns.

Option C) Check Sheet - This option is incorrect. A check sheet is a tool used to collect and record data, but it does not display the frequencies or distribution of the data.

Option D) Process Map - This option is incorrect. A process map is a graphical representation of a process flow, showing the sequence of steps and the relationships between them. It does not display the frequencies of measured data.

The correct answer is B) Histogram. This option is correct because a histogram is specifically designed to depict the frequencies or counts of measured data and display the distribution of the data.

Correct Option: D
Explanation:

To solve this question, the user needs to be familiar with different graphical tools used for quality improvement and problem-solving. The user also needs to understand the purpose and use of each tool.

Now, let's go through each option and explain why it is right or wrong:

A. Check Sheet: This option is incorrect. A check sheet is a tool used for data collection and tallying, not for ranking causes.

B. Cause and Effect Diagram: This option is incorrect. A cause and effect diagram, also known as a fishbone diagram, is used to identify and analyze the potential causes of a problem, not to rank causes.

C. Scatter Diagram: This option is incorrect. A scatter diagram is used to examine the relationship between two variables, not to rank causes.

D. Pareto Chart: This option is correct. A Pareto chart is a graphical tool used to prioritize and rank causes from most significant to least significant. It combines a bar chart and a line graph to visually represent the frequency or impact of each cause. The causes are ordered from left to right based on their contribution to the overall problem. The tallest bar represents the most significant cause, guiding improvement efforts towards addressing the vital few causes that contribute the most to the problem.

The Answer is: D. Pareto Chart
