Answer: (A)

Verified step by step guidance

1. Understand the types of data: Quantitative data refers to numerical values that can be measured or counted, while Nominal, Qualitative, and Categorical data refer to categories or groups without inherent numerical order.
2. Recall the purpose of a pie chart: Pie charts are designed to show proportions or percentages of categories within a whole, making them ideal for categorical or qualitative data.
3. Recognize that pie charts are not suitable for quantitative data because quantitative data involves numerical measurements that are better represented by histograms, line graphs, or scatter plots.
4. Identify that nominal, qualitative, and categorical data are all types of categorical data, which pie charts effectively display by showing the relative sizes of each category.
5. Conclude that the type of data generally not displayed using a pie chart is quantitative data, as pie charts do not effectively represent numerical measurements.
