Actual exam question for CompTIA's DA0-002 exam Question #: 49 Topic #: 2
The sales department wants to include the composition of total sales amounts across all three sales channels in a report. Given the following sample sales table: Sales channel Month Sales (million $) Digital January 135 Store February 145 Online March 165 Store April 200 Store May 125 Online June 155 Digital July 120 Online August 145 Digital September 160 Which of the following visualizations is the most appropriate?
This question pertains to theVisualization and Reportingdomain, focusing on selecting the appropriate visualization for a specific requirement. The task is to show the composition of total sales across three channels, which involves showing proportions. * Pivot table (Option A): A pivot table summarizes data but isn't a visualization; it's more for data exploration. * Pie chart (Option B): A pie chart shows the proportion of total sales for each channel (Digital, Store, Online), which is ideal for displaying composition. * KPI card (Option C): A KPI card displays a single metric, not suitable for showing composition across multiple channels. * Box plot (Option D): A box plot shows data distribution (e.g., quartiles), not proportions. The DA0-002 Visualization and Reporting domain emphasizes "translating business requirements to form the appropriate visualization," and a pie chart is best for showing the composition of totals.
