Each learning path is one chapter: a guided route through a topic, one small course at a time. Pick a class to see its chapters in order.
Two classes both have an average mark of 60. In one class every student scored close to 60. In the other, some scored 20 and some scored 100. The average alone cannot tell them apart. This chapter gives you the numbers that can: the range, the mean deviation, the variance and the standard deviation. Then you compare data sets, combine them, read quartiles and box plots, and measure how two quantities move together with correlation and regression. It covers the statistics unit of the Indian syllabus (NCERT, JEE Main) and the matching topics of A-Level, IB, AP Statistics and the SAT. Python checks every figure on the computer.
