Unit 6: Critiquing Qualitative and Quantitative Research Kaplan University July 16, 2013 Unit 6 Critiquing Qualitative and Quantitative Research The research conducted by Foster-Fitzpatrick, Ortiz, Sibilano, Marcantonio and Braun (1999) is a quantitative study of the significance of crossing the legs while blood pressure is being measured. The purpose of the research was to determine whether leg-crossing impacted the results of blood pressure measurements. The research conducted by Palese, Skrap, Fachin, Visioli and Zannini (2008) is a qualitative study of the subjective data collected from patients who experienced while-awake craniotomies.

Critique of Sampling Methodology Quantitative Critique of Sampling Methodology The convenience sampling that was used in recruiting all male patients who were on blood pressure medications is a glaring bias in this study. There was no information provided addressing why the patients were presenting to the clinic. There are many interventions that can raise blood pressure. For example, the study conducted by Marshall, Anantharachagan, Choudhary, Chue and Kaurhis, (2002) investigated the effect of situational anxiety on blood pressure experienced in anticipation of a blood test. Marshall, et. al., (2002) found that anticipation of a blood test can raise blood pressure. Foster-Fitzpatrick, et. al., 1999 did not address the purpose of the patient’s visit to the clinic. The researchers addressed known influential factors verbally, but not all factors were controlled during the experiment. For example, time of day, the white coat effect along with respirations and heart rate were not addressed in the results.

More commonly used existing frameworks tend to have been formulated within the quantitative research paradigm. While frameworks for critiquing qualitative research exist, they are often complex and more suited to the needs of students engaged in advanced levels of study. The framework presented in this article addresses both quantitative and qualitative research within one list of questions. ItRead MoreCritiquing A Qualitative And Quantitative Study912 Words   |  4 PagesCritiquing of a Qualitative and Quantitative Study The purpose of this paper will be to present the contrasts in the type of information that was gained while reviewing two studies.
