Grouped Frequency Tables

Q. The difference between the maximum and the minimum values is known as .

1. Sample
2. Range
3. Frequency
4. Data

Q. The number of students weighing less than 30 kg in a section is ten. There are 15 students who weigh less than 35 kg, and 20 students who weigh less than 40 kg.
The frequency table for the given data is a follows: Weight Range Number of Students

$0<\text{Weight (kg)}<30$	$10$
$0<\text{Weight (kg)}<35$	$15$
$0<\text{Weight (kg)}<40$	$20$

Then there are
students who weigh more than or equal to 35 kg.

Q. In grouped frequency data, the span of each interval is

1. Difference between upper limit and lower limit of each range.
2. Sum of upper limit and the lower limit of the data set.
