Question 1 Report
| Class Intervals | 0 − 2 | 3 − 5 | 6 − 8 | 9 − 11 |
| Frequency | 3 | 2 | 5 | 3 |
Find the mode of the above distribution.
Answer Details
Mode = L1 + ()C
D1 = frequency of modal class - frequency of the class before it
D1 = 5 - 2 = 3
D2 = frequency of modal class - frequency of the class that offers it
D2 = 5 - 3 = 2
L1 = lower class boundary of the modal class
L1 = 5 - 5
C is the class width = 8 - 5.5 = 3
Mode = L1 + ()C
= 5.5 + C
= 5.5 + x 3
= 5.5 +
= 5.5 + 1.8
= 7.3 = 7
D1 = frequency of modal class - frequency of the class before it
D1 = 5 - 2 = 3
D2 = frequency of modal class - frequency of the class that offers it
D2 = 5 - 3 = 2
L1 = lower class boundary of the modal class
L1 = 5 - 5
C is the class width = 8 - 5.5 = 3
Mode = L1 + ()C
= 5.5 + C
= 5.5 + x 3
= 5.5 +
= 5.5 + 1.8
= 7.3 = 7
