Before knowing, What are the Sources of Data, it is very important to know what is Data.
Meaning of Data
Data is any information that is obtained from a survey, experience or any other source. Data can be represented in different ways. Data can be represented in the form of numbers or through a picture or diagram. For example, "There are 40 boys and 50 girls in B.A. first year", in this example through 40 and 50 numbers, along with the number of students in the first year, the number of female students and male students in that class has also been mentioned. Thus through these data, information is received about first year students.
Let us now learn how we collect data or what are the sources of data.
Sources of Data
Data are divided into two main types on the basis of source.
1. Primary Data
2. Secondary Data
let's get to know them
1. Primary Data
Primary data refers to those data, which are collected by a student or researcher or any institution on their own. This type of data is collected for the first time by a student or researcher or any institution and these data have not been published in any other book, newspaper or any other medium, that is why they are called primary data.
For example- if a researcher himself goes door-to-door and conducts a survey that how many R.O. Water Filter are installed in a city, the data collected in this way by the researcher comes under primary data.
Sources of Primary Data Collection
Primary data can be collected in the following ways
1. Personal Observation
2. Interview
3. Questionnaire
4. Schedule
5. Other Mediums
2. Secondary Data
Secondary data refers to those data, which are not collected by any student or researcher or any institution themselves, but this type of data is already recorded or recorded in any published or unpublished and government or non-government sources. These data are collected and published by any other person or organization or researcher. Other people or researchers use them according to their convenience or need.
For example- if a researcher collects information through a published book or newspaper that how many R.O. Water Filter are installed in a city, the data collected in this way comes under secondary data, since here the data is not collected by the researcher or student going door-to-door in the city.
