Mean = (106+122+134+150+120+92+75)/7 = 799/7 ≈ 114.1429.
Absolute deviations: |106−114.1429|=8.1429, |122−114.1429|=7.8571, |134−114.1429|=19.8571, |150−114.1429|=35.8571, |120−114.1429|=5.8571, |92−114.1429|=22.1429, |75−114.1429|=39.1429.
Average = (8.1429+7.8571+19.8571+35.8571+5.8571+22.1429+39.1429)/7 ≈ 19.8367 ≈ 19.8.
Answer: 19.8.
