The number of members in 20 families are given as: 4,6,5,5,4,6,3,3,5,5,3,5,4,4,6,7,3,5,5,7. What is the number of families with less than 5 members?
The number of times a particular observation occurs is known as frequency.
Here in our data 4,6,5,5,4,6,3,3,5,5,3,5,4,4,6,7,3,5,5,7. we observe that number of families with less than 5 members in it are 8. Therefore the frequency of the number of families with less than 5 members is 8
