Question

in a frequency distribution, the median class is__. the class interval with the highest frequency any class interval the middle - class interval the class interval containing half of the total frequency

Explanation:

To determine the median class in a frequency distribution, we recall the concept of the median. The median is the middle value of a dataset when it's ordered. In a frequency distribution, we calculate the cumulative frequency. The median class is the class interval where the cumulative frequency first reaches or exceeds half of the total frequency (since the median is the value that splits the data into two equal - sized halves).

• The class interval with the highest frequency is the modal class, not the median class.
• A median class is not just any class interval.
• The "middle - class interval" is a vague description and not the correct definition. The correct definition is related to the cumulative frequency reaching half of the total frequency.

Answer:

the class interval containing half of the total frequency
