Question

make a frequency table with:
11,15,14,18,12,15,13,16,15,11,14,12,11,12,13,14,12,18,15,11 and the calculate the median, mean and mode.​

Answer 1

Respuesta:

Table:

11 ; 11 ; 11 ; 11 ; 12 ; 12 ; 12 ; 12 ; 13 ; 13 ; 14 ; 14 ; 14 ; 15 ; 15 ; 15 ; 15 ; 16 ; 18 ; 18

Median: 11 + 11 + 11 + 11 + 12 + 12 + 12 + 12 + 13 + 13 + 14 + 14 + 14 + 15 + 15 + 15 + 15 + 16 + 18 + 18 = 272 / 20 = 13,6

Median = 13,6

Mean = (13 + 14) / 2

Mean = 13,5

Mode = 15
