Question

acme co. sales data
product | % of total sales
toothpaste | 34
hand soap | 25
mouthwash | 17
shampoo | 14
deodorant | 10
options: bar graph, line graph, pie chart, scatter plot

Explanation:

Step1: Analyze data type

The data shows the percentage of total sales for different products, which are parts of a whole (total sales).

Step2: Evaluate graph types

• Bar graph: Compares quantities of different categories, not ideal for showing parts of a whole.
• Line graph: Shows trends over time, not applicable here.
• Pie chart: Represents parts of a whole as slices, perfect for percentage breakdowns.
• Scatter plot: Shows relationship between two variables, not relevant here.

Answer:

Pie chart
