Answer:
Step Deviation Method (Mean) Step Deviation : Sometimes, during the application of the short-cut method for finding the mean, the deviation d, are divisible by a common number 'h' .In this case the di = xi – A is reduced to a great extent as di becomes di / h.
This method is nothing but an extension of the shortcut method explained above. When the figures of deviations appear to be big, and divisible by a common factor, this method, the figures of deviations are reduced by dividing them all by a common factor. The formulas are thus modified as under:
Where, c = Common factor by which each of the deviations is divided
d1 = the deviation from the assumed average divided by the common factor i.e., X-A/C
