Consider what information you can get by reading each diagram:

  • what mark the majority and the minority of the students got,

  • which marks have the same number,

  • the number of students who got 3 was lesser or greater than the students who got 2.

Some of the information is easier to read by using one type of diagramdiagramdiagram.

By using the bar diagram you can read the following information:

  • the number of grades 6,

  • the number of students who wrote the test,

  • how many more grades 5 than 3 there were.

By using the pie chart you can read the following information:

  • the percentage of students who got grade 5,

  • whether the students who have got the grade 5 represent half of all the students writing the test.
