Discrete or Continuous Data Quiz

The number of students in a classroom.

• Discrete

• Continuous

Answer explanation

The number of students in a classroom is a countable value, meaning it can only take specific whole numbers (0, 1, 2, ...). This makes it a discrete variable, as opposed to continuous variables that can take any value within a range.

The height of a basketball player.

• Discrete

• Continuous

Answer explanation

The height of a basketball player is a continuous variable because it can take any value within a range, including fractions. Discrete variables, on the other hand, can only take specific, separate values.

The amount of money in a wallet.

• Discrete

• Continuous

Answer explanation

The amount of money in a wallet is discrete because it consists of distinct values (e.g., whole dollars or cents) rather than a continuous range. You cannot have a fraction of a physical bill or coin.

The time taken to run a marathon.

• Discrete

• Continuous

Answer explanation

The time taken to run a marathon is measured in hours, minutes, and seconds, which can take any value within a range. Therefore, it is a continuous variable, as opposed to discrete variables that have distinct, separate values.

The number of cars parked in a parking lot.

• Discrete

• Continuous

Answer explanation

The number of cars parked is countable and can only take whole number values (0, 1, 2, ...). This makes it a discrete variable, as opposed to continuous variables that can take any value within a range.

The weight of a watermelon.

• Discrete

• Continuous

Answer explanation

The weight of a watermelon is a measurable quantity that can take any value within a range, making it a continuous variable. Discrete variables, on the other hand, can only take specific, separate values.

The number of pages in a book.

• Discrete

• Continuous

Answer explanation

The number of pages in a book is a countable quantity, meaning it can only take specific integer values (1, 2, 3, etc.). Therefore, it is classified as discrete, not continuous, which would involve measurements that can take any value.

The amount of water in a swimming pool.

• Discrete

• Continuous

Answer explanation

The amount of water in a swimming pool is measured continuously, as it can take any value within a range. Unlike discrete quantities, which are countable, continuous quantities can vary infinitely, making 'Continuous' the correct choice.

The number of people in a restaurant.

• Discrete

• Continuous

Answer explanation

The number of people in a restaurant is a countable value, meaning it can only take specific whole numbers (0, 1, 2, ...). This makes it a discrete variable, as opposed to continuous variables that can take any value within a range.

The speed of a car on the highway.

• Discrete

• Continuous

Answer explanation

The speed of a car on the highway is measured in units like miles per hour, which can take any value within a range. This makes it a continuous variable, as opposed to discrete variables that can only take specific values.
