The value of K in the table can be calculated by finding the cumulative frequency at the end of the class interval B.
Cumulative frequency at the end of class interval B = Cumulative frequency at the end of class interval A + Frequency in class interval B
Cumulative frequency at the end of class interval A = 12
Frequency in class interval B = 4
Cumulative frequency at the end of class interval B = 12 + 4 = 16
The value of K in the table is 16.
Consider the following data:
19 10 9 8 14 11 11 12 11 9 19 19
17 10 13 18 16 17 5 14 11 15 18 12
8 7 10 16 2 12
Construct a frequency distribution by making the class width 3 and the lower limit of the first class 2.
