Answer» Given, Numbers of observations are given. To Find: Calculate the Mean Deviation from the mean. Formula Used: Mean Deviation = \(\frac{\Sigma f|d_i|}{n}\) Explanation. Here we have to calculate the mean deviation from Mean So, Mean = \(\frac{\Sigma f_ix_i}{f_i}\) Mean of the given data is \(\frac{433}{20}\) = 21.65
Mean Deviation = \(\frac{\Sigma f|d_i|}{N}\) Mean deviation for given data is \(\frac{25}{20}\) =1.25 Hence, The mean Deviation is 1.25. |
