Answer: (A)

Verified step by step guidance

1. Understand what a frequency table is: it is a way to organize data by listing each unique value or category along with the number of times it occurs (its frequency).
2. Recognize that categorical data consists of distinct categories or groups (like colors, brands, or types), which can be counted and displayed in a frequency table.
3. Recognize that numerical data consists of numbers, which can be either discrete (countable values) or continuous (measurable values). Both types can be grouped into intervals or listed individually to create frequency tables.
4. Note that continuous data can be grouped into intervals (called class intervals) to form a frequency table, while discrete numerical data can be listed directly with their frequencies.
5. Conclude that frequency tables can represent both categorical data and numerical data (discrete or grouped continuous), making the correct answer: Both categorical and numerical data.
