Question

Determine a média, a mediana e a moda,para cada um dos conjuntos.
a) 3,5,2,3,6,7,4,8,2,3,4,5

b) 12,13,14,1,2,3,12,11,11,11

Answer 1

a) 3, 5, 2, 3, 6, 7, 4, 8, 2, 3, 4, 5

MÉDIA: (3 + 5 + 2 + 3 + 6 + 7 + 4 + 8 + 2 + 3 + 4 + 5) / (12) = 52/12 = 13/3 ou 4.34 aproximadamente
MEDIANA: 2, 3, 4, 5, 6, 7, 8 = (2,8) (3,7) (4,6) = 5
MODA: (2, 2, 3, 3, 3, 4, 4, 5, 5) = 3

b) 12,13,14,1,2,3,12,11,11,11

MÉDIA: (12 + 13 + 14 + 1 + 2 + 3 + 12 + 11 + 11 + 11) / (10) = 90/10 = 9
MEDIANA: 1, 2, 3, 11, 12, 13, 14 = (1,14)(2,13)(3,12) = 11
MODA: 11, 11, 11, 12, 12 = 11
