First, find the mean:
\text{Mean} = \frac{10 + 12 + 14 + 15 + 17 + 19}{6} = \frac{87}{6} = 14.5
Now find the absolute deviations from the mean:
|10 - 14.5| = 4.5,\quad |12 - 14.5| = 2.5,\quad |14 - 14.5| = 0.5
Sum of deviations:
4.5 + 2.5 + 0.5 + 0.5 + 2.5 + 4.5 = 15
Mean deviation:
\frac{15}{6} = 2.5
Final Answer: 2.5
