Top Questions on frequency distributions
- Student-teacher ratio expresses the relationship between the number of students enrolled in a school and the number of teachers employed by the school. This ratio is important for a number of reasons. It can be used as a tool to measure teachers’ workload as well as the allocation of resources. A survey was conducted in 100 secondary schools of a state and the following frequency distribution table was prepared :Based on the above, answer the following questions :
Number of students per Teacher Number of Schools 20 - 25 5 25 - 30 15 30 - 35 25 35 - 40 30 40 - 45 15 45 - 50 10 - CBSE Class X - 2024
