What is a Data Set?
A DATA SET is defined as a collection of data summaries and analyses that are derived from a single, defined group of subjects. The specifications used for defining any given Data Set are stated on the corresponding Data Set page, which also states the total number of patients providing data for that Data Set (the "Overall Sample Number.")
In many of the
data summaries, the actual number of cases available for analysis is smaller than the "Overall Sample Number" for that Data Set, because not all questions or data items received responses from every patient in the sample. Therefore, in every data summary there is an explicit statement at the top showing the number of patients responding to the question or item under discussion.
Data Set 1
Summaries of data obtained from 1630 patients seen at the OHSU Tinnitus Clinic between 29.Dec.1981 and 14.Aug.1994. Data Set 1 replicates the original collection of information in the Oregon Tinnitus Data Archive 95-01, together with some newly prepared data summaries for that same patient sample. In addition a number of stylistic changes have been implemented, including graphic displays for many of the data summaries.
Data Set 2
Summaries of data obtained from 873 consecutive patients seen at the OHSU Tinnitus Clinic between 29.Dec.1981 and 11.Apr.1989. (Note that this group of patients is a wholly-contained subset of the group of patients providing data for Data Set 1.) Because of the large size of this subset, these gender-based analyses constitute robust estimates of the gender-based characteristics of the overall Clinic population. (Some of these analyses were published in: Meikle & Griest, 1989).
