  1. In a triangle test, what is the probability of choosing the odd sample correctly by guessing alone?

    Answer: 1/3

    With three samples and one odd, chance is 1 in 3.

  2. Which discrimination test presents a reference sample first, then two coded samples, one matching the reference?

    Answer: Duo-trio

    The duo-trio test asks which coded sample matches the reference.

  3. Why are three-digit random codes used to label samples in sensory testing?

    Answer: To reduce panelist bias from labels

    Random codes prevent letters or numbers from biasing perception.

  4. What is a Type II error (beta) in a difference test?

    Answer: Failing to detect a real difference

    Type II error means missing a true difference between products.

  5. Which is the best palate cleanser for most sensory evaluations?

    Answer: Room-temperature purified water and unsalted crackers

    Neutral water and unsalted crackers minimally interfere with flavor.
