The Advantages Of Quantitative And Qualitative Research Methods

1226 Words5 Pages
Quantitative and qualitative research methods are the two central methods for conducting research. Although there are both advantages and disadvantages to each of these research methods, many researchers decide to merely utilize one of the methods, without exploring the other method at all. This is a problem as these researchers only get to analyze their research from one point of view rather than from differing points of view. In other words, these researchers will solely rely on numbers and statistics or solely rely on interviews and observations. The researchers Bonta and Gendreau are open to utilizing both research methods, however, instead of simply using quantitative research methods. Conversely, the researchers Roberts and Jackson are…show more content…
Quantitative research methods involve the use of numbers to epitomize the ramifications of a study (Palys, 2014, p. 16). Quantitative research methods are also objective, with accurate measurement being the central aspiration (Palys, 2014, p. 16). Moreover, they involve the use of questionnaires and surveys, rather than the use of interviews or participant observation like in qualitative methods. In particular, Bonta and Gendreau did a qualitative and quantitative study on prison crowding and the effects that it has on one 's physiological, psychological and behavioural states. Notably, Bonta and Gendreau use numbers as evidence to elucidate that crowded prisons are capable of triggering physiological as well as psychological stress among prisoners (Bonta & Gendreau, 1990, p. 355). This elucidates that long-term confinement is indeed able to affect one 's mental state. In this study, Bonta and Gendreau use surveys to investigate the effects that overcrowding has on inmates by taking three variables into consideration; physiological, psychological, and behavioural measures. Physiological measures involve inmates ' blood pressure and heart rate, psychological measures involve inmates ' reports of crowding and discomfort, and behavioural measures involve assaults and misconducts on other inmates (Bonta & Gendreau, 1990, p. 352). These numbers would then provide the researchers…show more content…
557). That is to say, imprisonment is not sufficiently represented by studying human society and social relationships of imprisoned individuals, according to Roberts and Jackson. Additionally, they provide the reader with the notion that research that has been done so far contending that the effects of incarceration does not affect individuals mentally cannot be well substantiated. This makes the reader question whether or not Bonta and Gendreau are justifiable in their argument in stating that the imprisonment does not effect individuals mentally or emotionally. Roberts and Jackson use well founded, credible evidence to affirm that it cannot be corroborated that long-term confinement has no effect on a human being 's mental and emotional
