Data Collection

Successful completion of a sampling procedure involves researching the respondents and defining nature and the number of respondents involved. The researcher knows this stage not only what is being studied, but also who he needs to access for the necessary information. The information is available, make available the correct relationship between the researcher and the respondents is made.
Research tools are provided on subjects for the collection of verification or data. Most educational research will lead to the collection of data through a number of standardized test- or self-constructed research tools. It must provide objective data for the interpretation of the results achieved in the study. The data can be obtained through questionnaires, tests, personal observations, interviews and many other methods for collecting quantitative and qualitative evidence. Researchers need to know how much and what type of data collection will take place and when. He must also ensure that the types of data obtained from selected instruments are available in all model statistics that he or she wants to use to deliver the value of the research. The collection of data is the accumulation of specific evidence that allows the researcher to analyze the results of all activities in the right way through his design and research methods. The primary purpose of collecting data is to verify examination examinations.
Data collection is part of the research design, although we separate it. The collection of data is determined by the research method chosen for the project. Data can be collected in different ways, in different settings (fields or laboratories) and from different sources. These can be interviews - front interviews, telephone interviews, computer-assisted interviews and interviews with electronic media; questionnaires that are managed personally, sent by post or provided electronically; observing individuals and events that may participate or not participate.
            This connection is made through the methods of collecting data. In determining the method of collecting data to be used for the study, the researcher should keep two types of data in mind: primary data and secondary data.
                                    Data Collection Method
(a) Primary Data
The primary data is the data that was collected again and for the first time and thus happened to be original in nature.

The main observation is the collection of data through polls and surveys. The most important methodological aspect of this form of data collection. The primary data is the information collected by a researcher, specifically for a research assignment. In other words, the primary data is the information that a company collects because no one compiles and publishes information in a publicly accessible forum. Companies typically take the time and provide the resources needed to collect basic
data only when there is a question, problem or problem that happens to be significant or unique and requires the expenditures required to collect basic data.
Primary data sources include surveys, observations, experiments, questionnaire, personal interview etc.
(b) Secondary Data
The second data, on the other hand, is data that has been collected by other people and has gone through the statistical process.
The second collection of data is a separate theme in the Methodology series. Secondary data is data collected by a party that is not related to the research study, but this data is collected for a different purpose and at different times in the past. If the researchers use this data, they become secondary data for current users. They can be used in written, typed or electronic form.
Secondary data collection sources are government publications, websites, books, journal articles, internal records etc.
Difference between primary data and secondary data
Primary data
Secondary data
Primary data is one that is collected by the researcher for the first time
Secondary data is data collected or produced by others
True and original
The study and interpretation of primary data
Solving the problem-solving capacity
Collected for other purposes
Original in nature
Only analysis and interpretation
Originated by the researcher
Existing data previously collected by the investigator agencies and organisations
