TopicClass 10 · 7 topics
01
Mean of Grouped Data — Direct Method
Calculate the mean of grouped data using class marks and frequencies.
02
Mean — Assumed Mean & Step-Deviation Methods
Two faster methods for calculating the same mean, especially with large numbers.
03
Median of Grouped Data
Find the median using cumulative frequency and the median formula.
04
Mode of Grouped Data
Find the modal class and calculate the mode using the mode formula.
05
Cumulative Frequency Curves (Ogives)
Read and construct an ogive, and estimate the median graphically.
06
Theoretical Probability Basics
Classical probability: favourable outcomes over total outcomes.
07
Probability — Coins, Dice & Cards
