Ungrouped data is data in its original or raw form. The observations are not classified into groups.
For example, the ages of everyone present in a classroom of kindergarten kids with the teacher is as follows:
3, 3, 3, 3, 4, 4, 5, 3, 4, 3, 3, 3, 3, 4, 3, 27.
This data shows that there is one adult present in this class and that is the teacher.
In grouped data, observations are organized in groups.
For example, a class of students got different marks in a school exam. The data is tabulated as follows:
|No. of Students||13||9||36||32||10|
