(D) Step $ 1 $: Calculate the mean $ \bar{x} $ of the given data. $ \bar{x} = \frac{3 + 10 + 10 + 4 + 7 + 10 + 5}{7} = \frac{49}{7} = 7 $. Step $ 2 $: Calculate the absolute deviations from the mean $ |x_i - \bar{x}| $. $ |3 - 7| = 4 $ $ |10 - 7| = 3 $ $ |10 - 7| = 3 $ $ |4 - 7| = 3 $ $ |7 - 7| = 0 $ $ |10 - 7| = 3 $ $ |5 - 7| = 2 $ Step $ 3 $: Calculate the mean of these absolute deviations. $ 	ext{Mean Deviation} = \frac{4 + 3 + 3 + 3 + 0 + 3 + 2}{7} = \frac{18}{7} \approx 2.57 $.
