Methods for Collecting Data

Why Should I Care?

The scientific method depends on the quality of data that is collected. How you measure phenomena is really important if you want your analysis and conclusions to be credible.

There are actually several techniques, or research methods, for collecting data. Each method has its advantages and disadvantages, and its important to understand this because it will affect your conclusions. If a scientist wants to be respected and considered, they must be careful to use the correct research method, and to use it well. If not, the knowledge gathered in the research process will be useless, and maybe even harmful.

What are Methods for Collecting Data?

A research method is a

convention

Definitions

Research Method:                          A conventionscientists to use certain data collection instruments in specific ways to                           observe phenomena related to human characteristics, production, behaviour,                                                   and interaction. The method includes identifying relevant variables,                                                                       establishing a research question, and defining how to measure the variables.

 

 

Data collection instrument:
         A tool used to collect data, such as a questionnaire, an interview, a                                                                        laboratory, note-taking, and audio-visual recordings. We also include the                                                                             observation of artefacts,artifacts, landscape, and the physical world, as well as the                                                                           analysis of human production such as media, and art.

 

  • The Methods

Social Survey:
                                   a research technique that obtains information from a sample of individuals                                                        by asking questions and analyzing the responses

 Experiment:

 

Experiment:                                       A study where techniques are used to isolate, control, and manipulate the                                                                         major variables in a hypothesis.

 

 

Field Work:
                                        Research that involves studying social phenomena as they occur in the real                                                        world, naturally, without intervention.

 

 

Unobtrusive Measurement:
        The use of physical evidence, nonparticipant observations, and archival or                                                                          documentary evidence without the knowledge of participants.

 

 

Content Analysis:
                            The systematic analysis of ideas, themes, images, etc. in media.

 

 

 

Available Data:
The use of data which has already been collected by another group, such as a                                                   dataset from another scientist, from a governmental agency, a private                                                                   research firm, a corporation, or a public organization. 

 

 

Case Study:
                                        Research focussedfocused on one case of interest that is studied in great detail.

Objects of Measurement

 

Some methods are better suited for specific variables (in grey). This is for indication only. Each research project is different and may use any of the methods as seen fit.
