Respuesta:
GRUPO A: x = 18,14
Me = 17
Mo = 17
GRUPO B: x = 12,16
Me = 11,5
Mo = 11 y 21
GRUPO C: x = 25,79
Me = 24,5
Mo = 24
Explicación:
GRUPO A:
A. 15, 17, 13, 15, 17, 18, 19, 10, 24, 21, 22, 14, 17, 32
Media(x)
x = 10 + 13 + 14 + 15x2 + 17x3 + 18 + 19 +21 + 22 + 24 + 32/14 =
x = 254/14 x = 127/7 x = 18,14
Mediana(Me):
10,13,14,15,15,17,17,17,18,19,21,22,24,32 Me = 17+17/2
Me = 17
Moda(Mo): Mo = 17
GRUPO B:
B. 4, 1, 4, 8, 13, 12, 16, 24, 11, 11, 21, 21
Media(x):
x = 1 + 4x2 + 8 + 11x2 + 12 + 13 + 16 + 21x2 + 24/12=
x = 146/12 x = 73/6 x = 12,16
Mediana(Me):
1,4,4,8,11,11,12,13,16,21,21,24 Me = 11+12/2
Me = 11,5
Moda(Mo): Mo = 11 y 21
GRUPO C:
C. 28, 24, 33, 24, 35, 27, 27, 25, 24, 23 22, 25, 24, 20
Media(x):
x = 20 + 22 + 23 + 24x4 + 25x2 + 27x2 + 28 + 33 + 35/14=
x = 361/14 x = 25,79
Mediana(Me):
20,22,23,24,24,24,24,25,25,27,27,28,33,35 Me = 24+25/2
Me = 24,5
Moda(Mo): Mo = 24
RPTA:
GRUPO A: x = 18,14
Me = 17
Mo = 17
GRUPO B: x = 12,16
Me = 11,5
Mo = 11 y 21
GRUPO C: x = 25,79
Me = 24,5
