Key Topics to Revise
1
Mean of Grouped Data
- Mean is the average of all observations in a dataset
- For grouped data, we use class marks (mid-points) to represent each class
- Class mark = (Upper limit + Lower limit) ÷ 2
2
Mode of Grouped Data
- Mode is the value that appears most frequently in a dataset
- For grouped data, modal class is the class with highest frequency
- Mode lies within the modal class
3
Median of Grouped Data
- Median is the middle value when data is arranged in ascending order
- For grouped data, median lies in the median class
- Median class is found using cumulative frequency
