ICSE Class 10 Maths Measures of Central Tendency - Median and Mode
Median of Grouped Data
For finding the median we must arrange the given data in increasing or decreasing order.
The frequencies obtained by adding frequency of a class with the sum of frequencies of the preceding classes is called cumulative frequency.Mode of Grouped Data
The mode of data is the observation that occurs most often. If all the observations are occurring only once, mode is not defined.
The mode may be greater than, less than or even equal to the mean.
Mode is useful in market research.
