Carta Data Definitions and Sources
This page provides information about Carta’s data exhibits and
sources. Additional information about Carta’s research program is
available at cartalab.stanford.edu.
Information features that you find on the Carta page are listed
alphabetically below.
Course Reviews
This panel displays responses to the question, "What would you like to
say about this course to a student who is considering taking it in the
future?" You can filter course reviews by entering keywords, such as a
professor's name, into the keyword box. These data come from
Stanford’s official student course evaluation program.
Evaluations
These charts display students' average rating of particular professors
for the selected class. The data shown represent the past two years of
student evaluations. These data come from Stanford’s official student
course evaluation program.
Intensity
The upper chart displays an aggregated distribution of the reported
amount of time per week enrolled students spent working on the
selected class. The chart displays data from the past year of
evaluations. These data come from Stanford’s official student course
evaluation program.
The lower chart displays the outcomes of students who were enrolled in
the selected course. Either a student completed the course, dropped
the course (usually before the add/drop deadline), or withdrew from
the course (usually after add/drop deadline). This chart displays
data from the 2003-2004 school year to present. These data come from
the Stanford Registrar.
Performance
The upper chart chart displays an aggregated distribution of the
letter grades conferred in the selected course. The chart reports data
from the past ten years. These data come from the Stanford Registrar.
The lower chart displays the percentage of students who took the
course for credit (CR/S) or no credit (NC). These data from the
Stanford Registrar.
In order to protect student privacy, we do not display these charts
when there are fewer than fifteen grades to plot.
Sequencing
The upper left chart displays the grade years and categories of
students who have taken the selected class in the past two
years. These data come from the Stanford Registrar.
To the right of that chart is the course pairing tool. It enables you
to view statistics about when prior students took the selected course
in relation to other courses. By pairing your selected course with
other courses you have pinned, you can view the percentage of students
who took your selected course before, concurrently with, or after your
pinned ones. Additionally, you can view the average grade that
students received under any of the three possible sequences. You
cannot use this tool with courses that do not have any enrollment
overlap (i.e. no student took both course X and course Y). These data
come from the Stanford Registrar.
The lower left chart displays students’ self-reported reasons for
taking this course. These data come from Stanford’s official student
course evaluation program.
