Question

Determine a média, a moda e a mediana dos seguintes conjuntos de dados.
a) 8 ♦ 3 ♦ 1 ♦ 6 ♦ 8
c) 4 ♦ 10 ♦ 16 ♦ 20 ♦ 10
b) 8,5 ♦ 16,2 ♦ 2,6 ♦ 7,8 ♦ 6,0
d) 22 ♦ 3 ♦ 21 ♦ 2 ♦ 5

Answer 1

Resposta:

Explicação passo-a-passo:

a) 8 ♦ 3 ♦ 1 ♦ 6 ♦ 8

$M_{a} =\frac{8 +3 + 1 + 6 + 8}{5} = \frac{26}{5} = 5,2\\M_{o} = 8\\M_{e} = 6$

c) 4 ♦ 10 ♦ 16 ♦ 20 ♦ 10

$M_{a} =\frac{4 +10 +16 + 20 + 10}{5} = \frac{60}{5} = 12\\M_{o} = 10\\M_{e} = 10$

b) 8,5 ♦ 16,2 ♦ 2,6 ♦ 7,8 ♦ 6,0

$M_{a} =\frac{8,5 +16,2 + 2,6 + 7,8 + 6,0}{5} = \frac{41,1}{5} = 8,22\\M_{o} = sem moda \\M_{e} = 7,8$

d) 22 ♦ 3 ♦ 21 ♦ 2 ♦ 5

$M_{a} =\frac{22 +3 + 21 + 2 + 5}{5} = \frac{53}{5} = 10,6\\M_{o} = sem\\M_{e} = 5$
