7.5 Data Almanacs
Data almanacs are included for all student, teacher, and school background variables. The data
almanacs are text files that display unweighted summary statistics, by grade, for each
participating country on each variable included in the background questionnaires administered to
students, teachers, and school administrators or principals. The data almanac files corresponding
to each questionnaire type are listed in Table 7.15.

There are two types of displays in the data almanacs, depending on whether the item is a
categorical variable or a continuous variable. The display for categorical variables includes the
sample size, the count of students who were not administered the question, the count of students
choosing each of the options on the question, and the count of students who did not choose any of
the valid options to the questions. In cases where the question did not apply, the count of students
to whom the question did not apply is also presented in the almanac. An example of a categorical
variable almanac display is shown in Figure 7.2.
