A data frame with 51 rows and 6 variables:

participant_id: Respondent identifier
enjoy_generic: Degree of enjoyment of the juice sample with the Generic label, 1-10
enjoy_organic: Degree of enjoyment of the juice sample with the Organic label, 1-10
pay_generic: Price willing to pay for the with the Generic label, marked as $1-10 dollars in whole dollar amounts
pay_organic: Price willing to pay for the with the Organic label, marked as $1-10 dollars in whole dollar amounts
suspicious: Factor with two levels - suspicious and not suspicious

To what extent does the label on a beverage influence your enjoyment of the beverage? To find out, participants were asked to take part in a taste-test for grape juice. Each participant was poured 3 samples of grape juice: one from a bottle of Welch's Grape Fruit (a mid-level brand), one from a bottle of Generic Grape Fruit (a low-price brand), and one from a bottle of Whole Foods Organic Grape Juice (a high-priced brand). The trick was: it was all the same grape juice! Prior to the start of the project, the experimenters had poured out the original contents and poured the same Welch's grape juice into each bottle.

After each sample, participants rated their enjoyment of that juice (scale from 1 to 10). They also reported how much they would pay for a 1 gallon bottle of that juice ($1-10, whole dollar amounts). Finally, participants were debriefed about the study. Participants who expressed some suspicion during the debriefing that all the juices were actually the same were marked as suspicious; participants who expressed no suspicion were marked not suspicious.

This is a simplified dataset which contains data for only 2 of the 3 juice labels: Organic and Generic.

The data is from a student research project conducted by Sylvia Floretta-Schiller, Barbar Berent, and Gabriela Salinas in the Psychology Department at Dominican University.

The project was inspired by the following paper:
