Question 6

Explanation

A. Bar chart - This proposition is correct because a bar chart is an effective visual representation for displaying the age distribution of customers in different regions. The x-axis can represent the different regions, while the y-axis can represent the age groups. Each bar can represent the number or percentage of customers in each age group, allowing for easy comparison between regions. This type of chart is suitable for displaying categorical data and is commonly used for comparing different groups or categories. B. Heatmap - This proposition is incorrect because a heatmap is not the most suitable visual representation for displaying the age distribution of customers in different regions. Heatmaps are typically used to display the intensity or density of data on a two-dimensional grid, using colors to represent values. While a heatmap could potentially be used to show the distribution of customers across different age groups and regions, it may not provide a clear and concise representation of the data. C. Pie chart - This proposition is incorrect because a pie chart is not the most suitable visual representation for displaying the age distribution of customers in different regions. Pie charts are typically used to show the proportion or percentage of different categories within a whole. In this case, the age distribution of customers in different regions would require multiple pie charts, one for each region, which could become cluttered and difficult to compare. D. Stacked bar chart - This proposition is correct because a stacked bar chart is an effective visual representation for displaying the age distribution of customers in different regions. Similar to a regular bar chart, the x-axis can represent the different regions, while the y-axis represents the total number or percentage of customers. Each bar can be divided into segments, representing different age groups, stacked on top of each other. This allows for easy comparison of the age distribution within each region and between regions.
