6. Is the following qualitative or quantitative? "There are seven petals on the flower."

Correct Answer: Correct answer is: B) Quantitative.

Exam Relevance: AP Statistics, GRE, GMAT, SAT

Difficulty: Easy

Concept notes: Quantitative data involves numerical measurements or counts, while qualitative data involves descriptive or categorical information.

Common Mistakes: A common mistake is to confuse quantitative data with qualitative data. Qualitative data would describe the flower's color, shape, or texture, while quantitative data involves counting or measuring numerical values.

Explanations: The statement "There are seven petals on the flower" involves a numerical count, which is a characteristic of quantitative data. The number of petals is a measurable quantity, making it quantitative.

Option Analysis:

Option A: This option is incorrect because qualitative data would involve descriptive information, not numerical counts.
Option B: This option is correct because the statement involves a numerical count, which is a characteristic of quantitative data.
