Q1. Under exclusive method
Answer : Option B
Explaination / Solution:
Each class interval has two limits viz lower class limit and upper class limit. When developing a frequency distribution one usually looks at the type of variable discrete or continuous. when lower class limit is included but upper limit is excluded it is an exclusive class interval which is concerned with continuous variable.
Q2. The class mid-point is equal to
Answer : Option B
Explaination / Solution:
The lower limit for every class is the smallest value in that class. On the other hand, the upper limit for every class is the greatest value in that class. The class midpoint is the lower class limit plus the upper class limit divided by 2.
Q3. How individual series is differ from discrete series
Answer : Option B
Explaination / Solution:
Individual series are those series in which items are listened singely, discrete series are those series in which data are presented in manner that exact measurement of items are clearly shown.
Q4. Name the type of classification used in the following graph
Answer : Option D
Explaination / Solution:
Classification based on the analysis of spatial objects related to its spatial characteristics, such as areas of region, roads, and ponds or rives is known as spatial classification.
Q5.
Identify the type of classification used in the following table
Answer : Option A
Explaination / Solution:
When data are observed over a period of time the type of classification is known as chronological classification
Q6. Identify the type of classification from the following diagram
Answer : Option D
Explaination / Solution:
If a population is divided into a number of mutually exclusive classes according to some given characteristic and then each class is divided by reference to some second, third, etc. characteristic, the final grouping is called a manifold classification.
Q7.
Identify the type of variable from the following table
Answer : Option A
Explaination / Solution:
A continuous variable is a variable that has an infinite number of possible values. In other words, any value is possible for the variable. A continuous variable is the opposite of a discrete variable, which can only take on a certain number of values.
Q8.
From the Table given below identify the type of classification on the basis of class interval
Answer : Option A
Explaination / Solution:
No Explaination.
Q9. Expression of the class interval 90-99 in open ended classes
Answer : Option C
Explaination / Solution:
No Explaination.
Q10. There are two class interval 0-10 and 10-20 , if a student score 10 marks then he should be included in which class interval
Answer : Option A
Explaination / Solution:
This is an exclusive class interval. When the lower limit is included, but the upper limit is excluded, then it is an exclusive class interval.
