Histogram

Student test results can be exported to a histogram via two methods:

  • By using the hakutest-statistics executable (recommended for most users).
  • By using the hakutest statistics command.

Data format​

Test results statistics is exported as a PNG image with histogram as follows:

Histogram example

  • The horizontal axis indicates the number of points scored by students.
  • The vertical axis indicates the quantity of students who scored this number of points.

You can change the static text of the histogram by changing the configuration parameters. See Statistics internationalization for more information.
