Average deviation = mean of the absolute deviations from 9.25.
Dataset A: |7−9.25|+|9−9.25|+|9−9.25|+|12−9.25| = 2.25+0.25+0.25+2.75 = 5.5; 5.5/4 = 1.375.
Dataset B: |6−9.25|+|8−9.25|+|10−9.25|+|13−9.25| = 3.25+1.25+0.75+3.75 = 9.0; 9.0/4 = 2.25.
So A: 1.375 and B: 2.25.
Dataset A: |7−9.25|+|9−9.25|+|9−9.25|+|12−9.25| = 2.25+0.25+0.25+2.75 = 5.5; 5.5/4 = 1.375.
Dataset B: |6−9.25|+|8−9.25|+|10−9.25|+|13−9.25| = 3.25+1.25+0.75+3.75 = 9.0; 9.0/4 = 2.25.
So A: 1.375 and B: 2.25.
