Question
Construct a more than cumulative frequency distribution table.
C.I 50-60 60-70 70-80 80-90 90-100 100-110 F 13 15 17 21 23 19
| C.I | 50-60 | 60-70 | 70-80 | 80-90 | 90-100 | 100-110 |
| F | 13 | 15 | 17 | 21 | 23 | 19 |

Given thatC.I 50−60 60−70 70−80 80−90 90−100 100−110Frequency 13 15 17 21 23 19Now we can prepare a table for calculating more than cumulative frequency table.C.I Frequency More than cumulative frequency50−60 13 95+13=10860−70 15 80+15=9570−80 17 63+17=8080−90 21 42+21=6390−100 23 19+23=42100−110 19 19 _______ 108
Given that
C.I 50−60 60−70 70−80 80−90 90−100 100−110
Frequency 13 15 17 21 23 19
Now we can prepare a table for calculating more than cumulative frequency table.
C.I Frequency More than cumulative frequency
50−60 13 95+13=108
60−70 15 80+15=95
70−80 17 63+17=80
80−90 21 42+21=63
90−100 23 19+23=42
100−110 19 19
_______
108
