The first column is the frequency, that is the number of students with marks in a particular range. The second column, the stem, is the tens digit of the marks obtained by a student, and the third column, the leaf, is the ones digit of the marks. For example, the first line says that there are 58 students with marks between 00 and 09 followed by their marks. In this range the stem is 0 and the leaves vary between 0 and 9. Here we find that 7 students got 00 marks, four students got 01 marks, and 11 students got 05 marks, and so on. The second line, similarly, says that 57 students got marks in the range 10 to 19 and their marks and so on.
