On this Picostat.com statistics page, you will find information about the HearingTest data set which pertains to HearingTest. The HearingTest data set is found in the Stat2Data R package. You can load the HearingTest data set in R by issuing the following command at the console data("HearingTest"). This will load the data into a variable called HearingTest. If R says the HearingTest data set is not found, you can try installing the package by issuing this command install.packages("Stat2Data") and then attempt to reload the data.

HearingTest

Description

HearingTest

Format

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

Details

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.
