Sampling and Generalizability According to the article, quantitative research refers to the practice of quantifying the behavioral orientations of human beings with the intent of comparing either between various groups, or afore and after interruptions, such as emotions, thoughts and behaviors. Precision is one of the most vital aspects of quantitative research (Weir et al., 2002, p. 3). To suitably address the concerns of precision, analysts must also appreciate that there are numerous levels of measurement or variables. These include nominal, continuous, discrete, interval, ratio, and ordinal variables. In the article, Physical Activity in Pregnancy: A Qualitative Study of the Beliefs of Overweight and Obese Pregnant Women, the authors attempt to evaluate the experiences of overweight antenatal women and influence the interruptions that could encourage the acceptance of physical undertakings in the course of the prenatal period (Weir et al., 2002, p. 6).
The primary target population of the research were the pregnant women. The sampling procedure, on the other hand, involved the combination of the Concept of Planned Behavior and the Understated Realism approach. Through these two models, the authors intended to study the theoretical link between physical undertakings and beliefs of pregnant women within the context of their daily accomplishments (Weir et al., 2002, p. 3). The research samples were particularly chosen by purposive methods from previous studies entailing the measurements of physical interruptions in pregnancy. In addition, respondents were principally selected on the basis of Body Mass Catalogue at engagement. Comprehensive and semi-structured interviews were carried out with about ten overweight pregnant women and data exploration conducted using a framework approach (Weir et al., 2002, p. 2). The sample characteristics of the study can be said to have been restricted to a group of pregnant women, especially those who believe in healthy meeting, as well as those who believe in the effectiveness of physical activities.
