Plus remember that ø data is saying anything about the real situation of each family. Especially because ø get huge influenced by people with high salaries.
1+3+4+6+6+7+8 = 35
Mean = 35/7 = 5
Median means (1 3 4) 6 (6 7 8) = in the middle, so not (1+3+4+6 = 14) 6 (7+8 = 15)
In case there is just 1x6 then we get (1 3) (4 6) (7 8) —> (4+6)/2 = 5 as median and /(1+3+4+6+7+8)/6 = 4.8 as mean
