Stacked-column charts and stacked-bar charts can be difficult to perceive small differences inareas. The correct answer to the question is b.Stacked-column charts and stacked-bar charts are used to display the composition of a variable across differentcategories. They are useful when you want to show how a variable is divided into different components within each category.However, when the differences between the components are small, it can be difficult to perceive these differencesvisually.This is because stacked-column charts and stacked-bar charts use areas to represent the values of the components. The area of each component is proportional to its value, but our ability to perceive the difference between areas is limited.When thedifferencesbetween the areas are small, it becomes more difficult to distinguish between them, and we may have to rely on numerical values to understand the differences.In summary, the disadvantage of using stacked-column charts and stacked-bar charts is that they can be difficult to perceive small differences in areas. Therefore, it may be more effective to use other types of charts orgraphswhen the differences between the components are small.To learn more aboutchartsclick on,brainly.com/question/17607844#SPJ4...
