1Introduction to Statistics Ungrouped Data 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, 4, 3, 5, 4, 3, 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. Ungrouped data is easy to work when the data set is small. Grouped Data 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: Mark interval 0-20 21-40 41-60 61-80 81-100 No. of Students 13 9 36 32 10 This shows how many students got the particular mark range. Grouped data is easier to work with when a large amount of data is present.
