observe a nota de 10 alunos do 6° ano A :
10,0 - 5,0 - 7,0 - 8,0 - 5,5 - 6,5 - 10,0 - 9,0 - 4,0 - 6,0
determine a média a moda e a mediana dessas notas​

Answer 1

Explicação passo-a-passo:

Colocaremos a nota dos 10 alunos em ordem crescente:

[ 4,0 • 5,0 • 5,5 • 6,0 • 6,5 • 7,0 • 8,0 • 9,0 • 10,0 • 10,0 ]

Moda ( A nota que mais se repete )

ex: [ 4,0 • 5,0 • 5,5 • 6,0 • 6,5 • 7,0 • 8,0 • 9,0 • 10,0 • 10,0 ]

Moda = 10,0

Mediana ( A nota que ocupa o centro da lista )

ex: [ 4,0 • 5,0 • 5,5 • 6,0 • 6,5 • 7,0 • 8,0 • 9,0 • 10,0 • 10,0 ]

Mediana = 6,5 + 7,0

2

Mediana = 13,5

2

Mediana = 6,75

Média ( A soma de todas as notas divido pelo total de termos )

ex: 4,0 + 5,0 + 5,5 + 6,0 + 6,5 + 7,0 + 8,0 + 9,0 + 10,0 + 10,0 /10

Média = 71

10

Média = 7,1
