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

Concepts Used:
Frequency Distribution
A frequency distribution is a graphical or tabular representation, that exhibits the number of observations within a given interval. The interval size entirely depends on the data being analyzed and the goals of the analyst. The intervals must be collectively exclusive and exhaustive.
Visual Representation of a Frequency Distribution:
Both bar charts and histograms provide a visual display using columns, with the y-axis representing the frequency count, and the x-axis representing the variables to be measured. In the height of children, for instance, the y-axis is the number of children, and the x-axis is the height. The columns represent the number of children noticed with heights measured in each interval.
Types of Frequency Distribution:
The types of the frequency distribution are as follows:
- Grouped frequency distribution
- Ungrouped frequency distribution
- Cumulative frequency distribution
- Relative frequency distribution
- Relative cumulative frequency distribution
