Today I'll tell you how to find Standard Deviation (Linear Regression) by 3 different methods.
1. Standard Deviation (Linear Regression) in detailed pen-and-paper method.
3. Standard Deviation (Linear Regression) on Casio fx-82MS calculator
3. Standard Deviation (Linear Regression) in a shortcut method useful for competitive exams like CAT,MAT,XAT,GATE,JELET,AIEEE,JEE,IIT for MCQ questions.
I make videos on Statistics,Numerical Methods,
Business & Financial Mathematics,Operation Research,Computer Science & Engineering(CSE),Android Application Reviews,India Travel & Tourism,Street Foods,Life Tips and many other topics.
And a series of videos showing how to use your scientific calculators Casio fx-991ES & fx-82MS to do maths easily.
