Question

when class size varies , how do you select height for step deviation method in statistics?​

Answer 1

If class size varies then simply subtract 0.5 from each upper limit....then it will become equal class limit. Answer: If the class sizes are unequal, we can still use step deviation method by taking h to be a divisor of all di's. The example of this case is given in NCERT textbook on page 269.
