- 1. The following data shows the number of members in various families. Construct frequency distribution. Also find cumulative frequencies. 9, 11, 4, 5, 6, 8, 4, 3, 7, 8, 5, 5, 8, 3, 4, 9, 12, 8, 9, 10, 6, 7, 7, 11, 4, 4, 8, 4, 3, 2, 7, 9, 10, 9, 7, 6, 9, 5, 7.
- 2. The following data has been obtained after weighing 40 students of class V. Make a frequency distribution taking class interval size as 5. Also find the class boundaries and midpoints. 34, 26, 33, 32, 24, 21, 37, 40, 41, 28, 28, 31, 33, 34, 37, 23, 27, 31, 31, 36, 29, 35, 36, 37, 38, 22, 27, 28, 29, 31, 35, 35, 40, 21, 32, 33, 27, 29, 30, 23. Also make a less than cumulative frequency distribution. (Hint: Make classes 20-24, 25-29.....).
- Frequency Distribution: A frequency distribution is a tabular arrangement for classifying data into different groups and the number of observations falling in each group corresponds to the respective group. The data presented in the form of frequency distribution is called Grouped Data. Hence a frequency distribution is a method to summarize data.
- (i) Construction of Frequency Table: On the basis of types of variable or data, there are two types of frequency distribution. These are: (a) Discrete Frequency Distribution. (b) Continuous Frequency Distribution.
- (a) Discrete Frequency Table: Following steps are involved in making of a discrete frequency distribution:
- (i) Find the minimum and maximum observation in the data and write the values of the variable in the variable column from minimum to the maximum.
- (ii) Record the observations by using tally marks. (Vertical bar '1')
