In the same direction as the previous article, I should clarify that the sample is considered a census sample because 100% of the population is selected as it is considered a manageable number of subjects. In this sense, the census sample is one in which all the research units are considered as a sample.
In the perspective it adopts, it can be indicated that the population to be studied in some cases will be made up of people, since the information or data necessary for the development of the research projects will be extracted from them.
Regarding the techniques and instruments for data collection, according to what is established theoretically and in relation to the techniques and instruments for data collection, the following is mentioned:
They are the means that allow us to observe and record the characteristics or other data that we wish to obtain in a research and refer to What to collect the information with? The stages to be covered are: (a) specific objectives (chapter I), (b) operationalization of the variable(s) (chapter II), theoretical framework), (c) validation of the instrument, (d) reliability of the instrument (e) coding of the information for analysis.
Some authors define data collection techniques and instruments as the means or procedures by which the researcher will obtain the information to achieve the research objectives, so that the technique is defined as the set of procedures used during the data collection process.
