NCA-GENL Question 99
Select 3You are tasked with analyzing a dataset containing customer interactions with a company's AI chatbot. Your analysis includes identifying trends in the frequency of user queries over time and comparing the resolution rates of the chatbot across different regions. Which visualization tools and techniques would be most appropriate to convey these results effectively?
- A
A line graph to display trends in query frequency over time
- B
A bar chart to compare resolution rates across different regions
- C
A scatter plot to visualize the relationship between query frequency and resolution rates
- D
A pie chart to display the proportion of queries from each region
- E
A heatmap to show the frequency of queries by day and time
Show answer and explanation
Correct answers: A, B, E
Explanation
To convey the results of the analysis effectively, you should choose visualizations that match the data characteristics and the insights you want to communicate. A line graph is suitable for showing trends in query frequency over time, a bar chart works well for comparing resolution rates across regions, and a heatmap can highlight patterns in query frequency by day and time. These tools align with the goals of the analysis, making them the most appropriate choices.
- A. Correct.
A line graph is ideal for visualizing trends over time, making it suitable for displaying query frequency changes.
- B. Correct.
A bar chart effectively compares discrete categories, such as resolution rates across regions, and is appropriate for this analysis.
- C. Incorrect.
A scatter plot is used to explore correlations between two continuous variables, but it is not relevant for this specific analysis.
- D. Incorrect.
A pie chart is often used to show proportions, but it is not well-suited for trend analysis or regional comparisons in this context.
- E. Correct.
A heatmap is an effective visualization for showing query frequency patterns across two dimensions, such as day and time, making it relevant for this analysis.
