1. rata2 = 0+6+24+40+60+42 : 6
            = 172 : 6 = 25,33
modus = 4
median = tb+1/2n-fk : fme x P
            = 3,5+3-11:10 x 1
            = 3,5-0,8
            = 2,7
2. rata2 = 5+30+42+8x+27+10 : 16+x
          7,3    = 114+8x : 16+x
          114 + 8x = 116,8+7,3x
            8x-7,3x = 116,8-114
              0,7x = 2,8
                  x = 4
modus = 7
median = tb+1/2n-fk:fme.p
            = 5,5+3-6:6.1
              = 5,5-0,5
             = 5
yang nmr 3 soalnya apa??? smoga membantu
