63 - 67 | 1 | 1 | 0.01 | 1% |
58 - 62 | 5 | 6 | 0.06 | 6% |
53 - 57 | 10 | 16 | 0.16 | 16% |
48 - 52 | 12 | 28 | 0.28 | 28% |
43 - 47 | 25 | 53 | 0.53 | 53% |
38 - 42 | 18 | 71 | 0.71 | 71% |
33 - 37 | 10 | 81 | 0.81 | 81% |
28 - 32 | 7 | 88 | 0.88 | 88% |
23 - 27 | 7 | 95 | 0.95 | 95% |
18 - 22 | 5 | 100 | 1 | 100% |
Es necesario saber si los siguentes centiles de la tabla anterior estan correctos?
Determine los siguientes centiles:C25, C50,C75, C80,C90.
Presente el procedimiento.
1. .25 x100= 25
2. CF = 16
3. FC = 57.5
4. 25-16= 22
5. F = 10
C25= 57.5 + (9/10) *5= 62
1. .50 x 100= 50
2. CF = 28
3. FC = 52.5
4. 50-28= 22
5. F= 25
C50= 52.5 + (22/25) *5= 56.90
1. .75x100= 75
2. CF = 71
3. FC = 42.5
4. 75-71= 4
5. F= 10
C75= 42.5 + (4/10) * 5= 44.5
1. .80x100= 80
2. CF = 71
3. FC = 42.5
4. 80-71 = 9
5. F 10
C80= 42.5 + (9/10) * 5= 47
1. .90x100= 90
2. CF = 88
3. FC 32.5
4. 90-88 = 2
5. F = 7
C90= 32.5 + (2/7) * 5= 33.95
