# Free Presentation of Data 01 Practice Test - 11th Grade - Commerce

### Question 1

Which type(s) of presentation would you opt to present the annual expenditures of a company?

Textual

Diagrammatic

Tabular

None of these

#### SOLUTION

Solution :B and C

If textual was used, one has to go through the entire text for comprehension. In order to present data such as a company's annual expenditures/sales, one can use either tabular/diagrammatic presentation as it saves a lot of time and can be easily interpreted.

### Question 2

Descriptive presentation should be used when a report has to be made involving a huge amount of data.

#### SOLUTION

Solution :B

Descriptive method is not a concise representation and should not be used for any report involving huge amounts of data since this involves reading through the entire report/passage and is time-consuming. One can opt for tabular presentation in this case.

### Question 3

Spatial classification is based on the size of the geographies.

#### SOLUTION

Solution :B

Spatial classification is the classification based on places or location.The size of the place is not of concern. Example: villages, towns, cities fall under this category.

### Question 4

If you have referred some articles published in a magazine to make a report, then it is important to quote them by including a source note.

#### SOLUTION

Solution :A

It is mandatory to provide citations to the source in the source note while making a report.

### Question 5

Histograms can never be used to represent discrete variables/data.

#### SOLUTION

Solution :A

Histograms are drawn only for continuous variables. Unlike the bar diagrams, there are "no" gaps between the bars.

### Question 6

The intersection point of less than ogive and more than ogive gives the

#### SOLUTION

Solution :A

The intersection of less than and more than ogives is the median of the corresponding frequency distribution.

### Question 7

Which data can be used to plot an arithmetic line graph?

#### SOLUTION

Solution :A

A continuous arithmetic line graph can be plotted only when the data is continuous.

### Question 8

Less than ogive is a

#### SOLUTION

Solution :B

For less than ogive, the less than cumulative frequencies are plotted against the upper class boundaries of that class. Here, frequencies are added starting from the upper limit of the 1st class interval of the frequency distribution. The cumulative total tends to increase or remain the same. Hence, less than ogive is a non-decreasing graph.

### Question 9

A huge amount of data has to be analysed on priority. Which of the following would best suit to present this data?

#### SOLUTION

Solution :A

In geometric diagrams, the representations are shown through geometric shapes and figures. Circles and rectangles are among the shapes that are used for geometric diagrams. This helps in easily analysing a huge amount of data.

### Question 10

#### SOLUTION

Solution :B

Frequency polygons are plotted in the described manner.
