    AQA GCSE · Question 05.3 · Data Collection and Sampling Methods

    Is your quantitative variable discrete or continuous? Tick a box.

    Answer options:

    A.

    Discrete

    B.

    Continuous

    How to approach this question

    Consider the quantitative variable you chose in the previous part. Can it be counted in whole numbers (discrete), or can it take any value within a range (continuous)? For example, you count flowers, but you measure height.

    Full Answer

    A.Discrete✓ Correct
    This depends on the answer to 5.2. - If "Number of flowers used" was chosen, the answer is Discrete. - If "Cost to make" or "Selling price" was chosen, the answer is Continuous (as money can be measured to fractions of a penny, although it is recorded discretely here). However, for GCSE level, money is often treated as discrete. The most unambiguous discrete variable is "Number of flowers used". Let's assume this was chosen. Answer: Discrete
    Discrete data can only take certain values (like whole numbers). For example, the "Number of flowers used" must be an integer (e.g., 8, 9, 10); you cannot use 9.25 flowers. This is countable. Continuous data can take any value within a range. For example, height, weight, or time. The "Cost to make" and "Selling price" are technically continuous variables because they can be measured, but in practice, they are recorded to two decimal places. However, "Number of flowers used" is unambiguously discrete.

    Common mistakes

    ✗ Incorrectly classifying a countable variable (like number of flowers) as continuous. ✗ Incorrectly classifying a measurable variable (like cost) as discrete, although this is a common point of confusion.
