Given Table Summary:

The table shows the distribution of students' scores in a game:

a) Solutions:

i) Kelas Mod (Mode Class)

The mode class is the class interval with the highest frequency.
From the table, the class interval 40 – 49 has the highest frequency of 12.
Answer: Kelas mod = 40 – 49.

ii) Saiz Selang Kelas (Class Interval Size)

To calculate the class interval size:
$\text{Saiz Selang Kelas} = \text{Upper Limit} - \text{Lower Limit of a Class}$ Using the first class interval (10 – 19):
$\text{Saiz Selang Kelas} = 19 - 10 = 10$
Answer: Saiz Selang Kelas = 10.

iii) Julat (Range)

The range is calculated as:
$\text{Julat} = \text{Highest Value} - \text{Lowest Value}$ From the table, the highest value is 69 (upper limit of last class) and the lowest value is 10 (lower limit of first class).
$\text{Julat} = 69 - 10 = 59$
Answer: Julat = **59
