Answer to Question 1

There will be three samples of yogurt given to each panelist in clear, unlabeled cups. The vanilla yogurt samples will be served in the same proportions. Two of the samples contain vanilla yogurt A and one contains vanilla yogurt B. The panelists will identify the odd sample (vanilla yogurt B) after tasting each sample.

Answer to Question 2

Paired comparison tests have two coded samples that are presented simultaneously and evaluated for intensity of a specific characteristic. One advantage of a paired comparison test is the small number of samples to analyze. Panelists are asked to select a specific characteristic (sweet, sour, thick, thin, etc.) and are not required to give descriptions. A disadvantage is that a product's appearance can affect the sensory panelists' evaluation and there is room for individual biases.
