Answer 2

To find the arithmetic mean by step deviation method

Given

Formula for arithmetic mean using step deviation method is given below

Arithmetic mean = A +∑$\frac{( f.d )}{N}$ × i

Where, "A" represents arbitrary or assumed mean.

            "f" represents frequency.

            "i" can be calculated as upper limit - lower limit.

            "d" represents deviation from the arbitrary or assumed mean.

                               d = $\frac{x - A}{i}$    

                               "x" is a data given in a particular question.

                               "A" is an assumed mean.

                               "i" represents class size.
