Question

Define data.what are the main sources of sources of data(3-4) marks

Answer 1

Data are raw facts and figures (ie) Unorganised information. Data as a general concept refers to the fact that some existing information or knowledge is represented or coded in some form suitable for better usage or processing. Raw data ("unprocessed data") is a collection of numbers or characters before it has been "cleaned" and corrected by researchers.

Following are the two sources of data:

1. Internal Source

• When data are collected from reports and records of the organization itself, it is known as the internal source.
• For example, a company publishes its ‘Annual Report’ on Profit and Loss, Total Sales, Loans, Wages etc.

2. External Source

• When data are collected from outside the organization, it is known as the external source.
• For example, if a Tour and Travels Company obtains information on ‘KarnatakaTourism’ from Karnataka Transport Corporation, it would be known as external sources of data.

Answer 2

Answer:

Data are characteristics or information, usually numerical, that are collected through observation. In a more technical sense, data are a set of values of qualitative or quantitative variables about one or more persons or objects, while a datum (singular of data) is a single value of a single variable.

Primary data sources include information collected and processed directly by the researcher, such as observations, surveys, interviews, and focus groups. Secondary data sources include information retrieved through preexisting sources: research articles, Internet or library searches, etc.
