Answer 1

- Media aritmética

•4+10+12+10+5+5+6+4+10+4+4+4+12+12 ÷ 14

102÷14 = 7.2857

•15+19+10+25+19+15+15+19+19+19+19 ÷ 11

194÷11 = 17.636363

•8+2+8+5+5+8+8+8+8+8+8+8+5+5+2+2+2+2 ÷ 18

102÷18 = 5.6666

•28+39+42+29+40+40+36+46+41+30+28+28 ÷ 12

427÷12 = 35.5833

•133+215+250+108+206+159+133+133 ÷ 8

1337÷8 = 167.125

•76+94+76+82+78+86+90+76+76+76+76 ÷ 11

886÷11 = 80.5454

- Mediana

• Me= 4,4,4,4,4,5,5,6,10,10,10,12,12,12

Me= 5+6 ÷ 2 = 11÷2 = 5.5

Me= 5.5

• Me= 10,15,15,15,19,19,19,19,19,19,25

Me= 19

• Me= 2,2,2,2,2,5,5,5,5,8,8,8,8,8,8,8,8,8

Me= 5+8 ÷ 2 = 13÷2 = 6.5

Me= 6.5

•Me= 28,28,28,29,30,36,39,40,40,41,42,46

Me= 36+39 ÷ 2 = 75÷2 = 37.5

Me= 37.5

•Me= 108,133,133,133,159,206,215,250

Me= 133+159 ÷ 2 = 292÷2 = 146

•Me= 76,76,76,76,76,76,78,82,86,90,94

Me= 76

- Moda

•4,10,12,10,5,5,6,4,10,4,4,4,12,12

Mo= 4

•15,19,10,25,19,15,15,19,19,19,19

Mo= 19

•8,2,8,5,5,8.8,8,8,8,8,8,5,5,2,2,2,2

Mo= 8

•28,39,42,29,40,40,36,46,41,30,28,28

Mo= 28

•133,215,250,108,206,159,133,133

Mo= 133

•76,94,76,82,78,86,90,76,76,76,76

Mo= 76
