Verified step by step guidance

1. Understand the definition of discrete quantitative data: Discrete data refers to countable data, often represented by whole numbers, where each value is distinct and separate.
2. Identify the characteristics of each option: Discrete data typically involves counting items or occurrences, whereas continuous data involves measurements that can take any value within a range.
3. Analyze the options: The weight of a bag of apples, temperature in a classroom, and time taken by a swimmer are examples of continuous data because they can take any value within a range and are measured rather than counted.
4. Consider the correct answer: The number of goals scored by a soccer team is discrete because goals are counted in whole numbers, and you cannot score a fraction of a goal.
5. Conclude that discrete data is characterized by countable, distinct values, such as the number of goals scored, which fits the definition of discrete quantitative data.
