Question

Calcule a média aritmética a moda e a mediana de cada conjunto de valores

A) 3 8 15 5 3 12 7 11

B) -20 5 8 -1 12 - 24 6 10 -3 16 -1 -8 0

Answer 1

A)

Ma = (3 + 8 + 15 + 5 + 3 + 12 + 7 + 11) / 8
Ma = 64 / 8
Ma = 8

Moda = 3

M = (3 + 8 + 15 + 5 + 3 + 12 + 7 + 11) / 2
M = 64 / 2
M = 32

B)

Ma = (- 20 + 5 + 8 - 1 + 12 - 24 + 6 + 10 - 3 + 16 - 1 - 8 + 0) / 13
Ma = 0 / 13
Ma = 0

Moda = - 1

M = (- 20 + 5 + 8 - 1 + 12 - 24 + 6 + 10 - 3 + 16 - 1 - 8 + 0) / 2
M = 0 / 2
M = 0
