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
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

Secondary data is
data collected or produced by others
