Question about Health & Beauty
Mean deviation is calculated by the following steps:
1. Add all the numbers and then divide by total number of values. That is take a mean.
2. Then subtract the mean from each values and ADD them all
3. then the added answer must be divided by the total number of values. and you get the Mean devaition.
I solved your problem here in steps:
(121+122+123+124+125+126) / 6 Equals to 102.6
(121-102.6) + (122-102.6) ...... +(126-102.6)
125.4/6 = 20.9 is the MEAN DEVIATION
Hope so this will help you.
