Question

true and false statement:
(a) In a bar graph, the width of bars may be unequal.
(b)In a bar graph, bars of uniform width are drawn horizontally only.
(c)When the observations are large numbers, we represent the information using a scale.
(d) In a bar graph, each bar (rectangle) represents only one value of the numerical data.
(e) The pictographs are useful fo​r visual comparisons of data.​

Answer 1

Step-by-step explanation:

In a bar graph, the width of bars may be unequal.

Solution:

False

Since, a bar graph is a pictorial representation of the numerical data by a number of bars of uniform width erected horizontally or vertically with equal spacing between them.In a bar graph, bars of uniform width are drawn vertically only.

Solution:

False

Bars of uniform width can be drawn vertically or horizontally.

Question 8:

In a bar graph, the gap between two consecutive bars may not be the same.

Solution:

False

In a bar graph, the gap between two consecutive bars must be equal.

Question 9:

In a bar graph, each bar (rectangle) represents only one value of the numerical data.

Solution:

True

In a bar graph, each bar (rectangle) represents only one value of the numerical data.

Question 10:

To represent the population of different towns using bar graph, it is convenient to take one unit length to represent one person.

Solution:

False

We take scale as per the given data.Pictographs and bar graphs are pictorial representations of the numerical data.

Solution:

True

Pictographs and bar graphs are pictorial representations of the numerical data.

Question 12:

An observation, occurring five times in a data is recorded as | | | | | using tally marks.

Solution:

False

The numerical data five represented as using

tally marks. then the symbol True

Answer 2

The following statements are true and false:-

• In a bar graph, the width of bars may be unequal: False The width of bars in a bar graph are equal.
• In a bar graph, bars of uniform width is drawn horizontally only: False Bars can be drawn both vertically and horizontally with uniform width.
• When the observations are large numbers, we represent the information using a scale: False In such a case usually tally marks or other methods of statistics are used.
• In a bar graph, each bar represents only one value of the numerical data: True One bar can only represent one unique value in a bar graph.
• The pictographs are useful for visual comparisons of data: True Pictographs are a great help in visualizing and comparing data.
