Q1. In volume diagram the three dimensions which are taken into account are:
Answer : Option A
Explaination / Solution:

For calculating volume, height, length and breadth is required

Q2. A pie diagram is also called:
Answer : Option C
Explaination / Solution:

Pie diagrams can be prepared by converting frequencies into angles in such a way that total of all angles should come equal to 360

Q3. Frequency curve
Answer : Option C
Explaination / Solution:

Data in the form of grouped frequency distributions are generally represented by frequency diagrams like histogram, frequency polygon, frequency curve and ogive.

Q4. With the help of histogram we can draw
Answer : Option A
Explaination / Solution:

Frequently distribution can be framed from histogram. Frequently polygon and frequency curve can be prepared by converting the mid points of histogram.

Q5. The most commonly used device of presenting business and economic data is:
Answer : Option B
Explaination / Solution:

Bar diagrams are very simple to understand and most suitable for presenting year wise data of sales, profits, etc of the business.

Q6. Sometime data is given is such that it begins far away from zero then a line is drawn called
Answer : Option D
Explaination / Solution:

Normal base line starts with zero, if the data is far away from zero, it becomes very difficult to present the data in a graph which is far away from the point of origin, therefore, a false base line is prepared.

Q7. Area diagrams are
Answer : Option D
Explaination / Solution:

A shape with only two dimensions (such as width and height) and no thickness are called two dimensional diagrams. Squares, Circles, Triangles, etc are two dimensional objects.

Q8. Which of the following is a type of bar diagram?
Answer : Option B
Explaination / Solution:

Component bar diagrams or charts , also called sub­diagrams, are very useful in comparing the sizes of different component parts (the elements or parts which a thing is made up of) and also for throwing light on the relationship among these integral parts. For example, sales proceeds from different products, expenditure pattern in a typical Indian family (components being food, rent, medicine, education, power, etc.), budget outlay for receipts and expenditures, components of labour force, population etc. Component bar diagrams are usually shaded or coloured suitably.

Q9. One dimensional diagram is:
Answer : Option A
Explaination / Solution:

In line diagrams, only one line passes through a vertex therefore it is a one dimensional diagram.

Q10. Two dimensional diagrams used in surface diagrams are:
Answer : Option B
Explaination / Solution:

A shape with only two dimensions (such as width and height) and no thickness. Squares, Circles, Triangles, etc are two dimensional objects.
