man_id subgroup power group
1 sub_A positive Group_A
2 Sub_B Negative Group_A
3 Sub_A Negative Group_B
4 Sub_B Positive Group_B
5 Sub_A Negative Group_A
6 Sub_B Positive Group_A
7 Sub_A Negative Group_B
8 Sub_B Positive Group_B

Total Power of Subgroup Sub_A in the Group Group_A is (Positive + Negative ) = Neutral
Total Power of Subgroup Sub_B in the Group Group_A is (Negative + Positive ) = Neutral
Total Power of Subgroup Sub_A in the Group Group_B is (Negative + Negative ) = 2 Negative
Total Power of Subgroup Sub_B in the Group Group_B is (Positive + Positive ) = 2 Positive

So the power of Sub_A in the Group_A is not equal to power of Sub_A in the Group_B
So the power of Sub_B in the Group_A is not equal to power of Sub_B in the Group_B
