Final Answer:
The best graphical representation for this data would be a bar chart or pie chart.
Step-by-step explanation:
Data type: We have categorical data with four categories (Health & Medicine, Beauty, Household, Grocery).
Objective: We want to visualize the distribution of purchases across these categories.
Unsuitable options:
Box plot: Requires quantitative data (numerical values) for each category, which is not available here.
Line plot: Doesn't effectively represent categorical data.
Histogram: More suitable for continuous data with frequency distribution.
Stem-and-leaf plot: Cumbersome for visualizing four categories with different frequencies.
Suitable options:
Bar chart: Clearly represents the frequency of each category with bars of different heights, making it easy to compare the proportions.
Pie chart: Offers a circular representation of the data, highlighting the relative size of each category.
Both bar charts and pie charts can effectively display the distribution of purchases in this scenario. The choice ultimately depends on the specific focus of the analysis and your preference for visual representation
