A dataset with 96 observations on the following 3 variables.

Subj Subject number (1 - 24)
List List of words: L1 L2 L3 L4
Percent Percent (out of 50) of words correctly identified


Audiologists use standard lists of 50 words to test hearing; the words are calibrated, using subjects with normal hearing, to make all 50 words on the list equally hard to hear. The goal of the study described here was to see how four such lists, denoted by L1-L4 in this dataset, compared when played at low volume with a noisy background. The response is the percentage of words identified correctly.
