Odpowiedź:
a)
śr = (8 + 2 + 6 + 8 + 4 + 2 + 3 + 4 + 8) / 9 = 5
mediana : 2, 2, 3, 4, 4, 6, 8, 8, 8
Me = 4
D = 8 - Dominata
b)
śr = (97 + 65 + 58 + 67 + 87 + 42 + 34 + 54)/8 = 63
mediana: 34, 42, 54, 58, 65, 67, 87, 97
Me = (58+65)/2 = 61,5
D = brak
c)
śr = (15 + 13 + 19 + 17 + 25 + 13 + 23 + 18 + 19 + 17)/10 = 17,9
mediana: 13, 13, 15, 17, 17, 18, 19, 19, 23, 25
Me = (17+18)/2 = 17,5
D1 = 13
D2 = 17
D3 = 19
d)
śr = (90 + 105 + 125 + 135 + 145 + 160 + 160 + 175 + 255)/9 = 150
mediana: 90, 105, 125, 135, 145, 160, 160, 175, 255
Me = 145
D = 160
