Data Collection Methods

There are several data collection methods that we have discussed including interviews, discussion groups and review of articles. The method used is larger determined by the research question. However, each method has its advantages and disadvantages. I will be comparing interviewing and review of articles. First, interviewing is used to collect primary data while review of articles collects secondary data (Rubin & Rubin, 2012). This shows that interviewing is much more reliable to the researcher since it gives the researcher the chance to interact with the respondents. However, interviewing is time consuming. One has to interview one respondent at a time which can take up much time. However, article review does not require a lot of time to wide up. One can review articles and videos much faster than interviewing.

The main advantage of interviewing is that the researcher gets a chance to observe other things such as facial expressions and body language which is not possible in documents review. Body language is very significant in research a since it can explain some phenomenon (Ravitch & Carl, 2016). If not captured, it can introduce a bias in the study. One can also record an interview to review later. Use of interviewing is however only limited to the available participants as opposed to review of documents. One can review many documents as possible but this can be said about the participants. One can only use a sample to represent the whole population.

For my research, it involves direct observations and personal questions which call for interviewing. Observations cannot be found in documents review but one can observe the participants while conducting the interview. In addition, the kind of questions I am looking to ask are very personal and specific and thus require the participant to answer directly.

Hi Sittipong, nice work over there, you have demonstrated the knowledge of the different data collection methods preferably interviewing and article reviews. The style the researcher is comfortable with dictates the data collection method. While the use of interviews is constrained by time, article review is much faster but again, with article reviews, one cannot capture other aspects such as body language. The time allowed for interviewing may collide with the schedules of the participants which cannot happen with article reviews which can be done any time anywhere. Interviews allow the researcher to ask for elaboration from the participant. When reviewing articles, the researcher depends solely on his/her understanding of what is written in the article. There is no room for clarifications. I like your choice of interviewing depending on your research question. There are many articles about this topic but use of real life experiences from participants will be very informing and you will also be able to observe their body language.

Hi Tekeilla, great line of thought over there. I agree reviewing takes more preparation time as compared to reviewing documents and videos. One cannot just wake up and decide to conduct interviews. Preparations have to be done well before and the participants informed. However, with documents review, no preparation is required. It can be done any time and there is no one to be informed. However, the researcher depends on his/her understanding of the information in documents. In interviews, the researcher can ask the respondent to elaborate on something. In addition, the researcher can also record some observations and body language. I like the fact that you acknowledge the technology available these days that are used for interviewing, however, your choice of face to face interviews is in line with your research question. Face to face interviews and group discussions are very effective when dealing with a qualitative research as opposed to documents reviews.
