Cumulative Frequency Distribution Table for Marks Obtained by Students
To construct a cumulative frequency distribution table, we need to follow these steps:
Step 1: Sort the data in ascending order
The given data: 3, 25, 48, 23, 17, 13, 11, 9, 46, 41, 37, 45, 10, 19, 39, 36, 34, 5, 17, 21, 39, 33, 28, 25, 12, 3, 8, 17, 48, 34, 15, 19, 32, 32, 19, 21, 28, 32, 20, 23
Sorting the data in ascending order: 3, 3, 5, 8, 9, 10, 11, 12, 13, 15, 17, 17, 17, 19, 19, 20, 21, 21, 23, 23, 25, 25, 28, 28, 32, 32, 32, 33, 34, 34, 36, 37, 39, 39, 41, 45, 46, 48, 48
Step 2: Determine the number of observations
The number of observations in the data set is 40.
Step 3: Determine the class intervals
We can choose class intervals based on the range of the data. In this case, we can choose a class width of 10.
Class intervals:
1-10, 11-20, 21-30, 31-40, 41-50
Step 4: Determine the cumulative frequency
To calculate the cumulative frequency, we count the number of observations less than or equal to each class interval.
Class Interval | Frequency | Cumulative Frequency
1-10 | 4 | 4
11-20 | 8 | 12
21-30 | 6 | 18
31-40 | 10 | 28
41-50 | 12 | 40
Step 5: Interpret the cumulative frequency distribution table
The cumulative frequency distribution table shows the number of students who scored marks within or below a particular range. For example, there are 4 students who scored marks between 1 and 10, and a total of 12 students who scored marks between 1 and 20.
By analyzing the cumulative frequency distribution table, we can easily identify the number of students falling within different mark ranges. This information helps in understanding the overall performance of the students and identifying any patterns or trends in the data.

Sorting the data in ascending order: 3, 3, 5, 8, 9, 10, 11, 12, 13, 15, 17, 17, 17, 19, 19, 20, 21, 21, 23, 23, 25, 25, 28, 28, 32, 32, 32, 33, 34, 34, 36, 37, 39, 39, 41, 45, 46, 48, 48

Class Interval | Frequency | Cumulative Frequency
1-10 | 4 | 4
11-20 | 8 | 12
21-30 | 6 | 18
31-40 | 10 | 28
41-50 | 12 | 40
