Statistical graphs

Teachers can now add statistical graphs to a short-answer question type and ask students to answer by interacting with the dynamic graph. The following statistical representations are available: bar chart, line chart and pie chart.
All statistical charts designed within Wiris Quizzes are interactive and customizable, and our software system automatically evaluates assessments with graphical statistical questions.
