Instrumentos de recolección de datos en investigación

Data collection instruments are the tools and methods used to gather and record information for research or evaluation projects. These instruments can include surveys, questionnaires, interviews, focus groups, observations, tests, and more. In this article, we will focus on the subtopics of interviews, case studies, and evaluatives and discuss their role in data collection.

Interviews

Interviews are a type of data collection instrument that involves verbal communication between an interviewer and a participant. They can be structured, where a set of standardized questions is asked, or unstructured, where the interviewer can modify the sequence and wording of questions. Interviews can also be non-directive, where the interviewer asks open-ended questions and uses spontaneous engagement to elicit more information, or focus, where the emphasis is on the interviewee's subjective and personal responses. Focus groups are a type of interview where a group of selected participants are asked about their opinion or perceptions concerning a particular topic. Interviews are useful for collecting rich and in-depth data, but they can be time-consuming, subjective, and difficult to replicate.

Case Studies

Case studies are another type of data collection instrument that involves examining a real-life situation or problem. They are often used in research to explore complex phenomena or to identify best practices. A case study can focus on a single individual, group, or organization, and it can be qualitative, quantitative, or a combination of both. Case studies are useful for gathering detailed information about a specific situation or problem, but they can be limited in their generalizability and may be subject to observer bias.

Evaluatives

Evaluatives are data collection instruments used to assess the quality or performance of a program, product, or service. They can include surveys, questionnaires, interviews, and observations. Evaluatives are useful for gathering feedback and identifying areas for improvement, but they can be subject to response bias and may not provide a comprehensive view of the situation.

In conclusion, data collection instruments are essential tools for gathering and recording information for research or evaluation projects. Interviews, case studies, and evaluatives are just a few examples of the types of instruments that can be used. Each type has its strengths and limitations, and the choice of instrument will depend on the research objectives, the type of data needed, and the available resources.
