8
The difference between the maximum and minimum observation in the data is _________________
Class Interval
9
0-10, 10-20, 20-30 .... so on are the classes, the lower boundary of the class interval 20 - 30 is _______________ .
Which of the following statement is true regarding range of data:
1. It tells us how widely the numbers are spread.
2. It is the difference of the highest and the lowest observation.
3. To calculate it we find the maximum and the minimum value in the data, and then the difference between the two is calculated.
Only 1 and 2
Only 2 and 3
Only 1 and 3
1, 2 and 3
11
The class mark of the class is 25 and if the upper limit of that class is 32, the lower limit for that class is ______________________.

3. It is the average number of observations.
13
The inclusive form of class boundary is defined as ________________________________________.
The class interval is defined as lower limit inclusive and the upper limit exclusive.
The true limit of a class is obtained by subtracting 0.5 from the lower limit of the class and the true upper limit of the class is obtained by adding 0.5 to the upper limit.
It is equal to half of the sum of the lower and upper limits of a class
