This type of qualitative research study focuses on the essence of a phenomenon as experienced by people.Phenomenology *%Which of the following is not a step in the phenomenologic approach? Inferring *%What is the basic social process women use through their menopausal transition?" is an example of a research question within which of the following traditions?Grounded theory *%"What is the essence of a mans experience with chemotherapy treatments for testicular cancer" is an example of a research question from which type of qualitative researcher?Phenomenology *%Have you grasped the essential concepts related to the design of quantitative research studies? Take the following true/false test to find out.%The researcher manipulates the dependent variable in experimental research. (F)%The experimental treatment is the independent variable. (T)%The one-group pretest-posttest design is an example of a pre-experimental design. (F)%The type of research that has the least controls associated with it is called quasi-experimental. (F)%The major threat to the external validity of a nonexperimental study is the selectionthreat. (F)
%The threat of mortality stems from differential attritions from groups. (T)%The threat of maturation can be related to factors such as growth and fatigue of subjects. (T)%If there is no constancy of conditions in a study, history becomes a potential threat to the external validity of the study. (F)%More than one type of research control may be used in a study. (T)%Retrospective designs are stronger in determining causal relationships that prospective designs. (F)%A study that focused on development among preterm infants would ideally be a longitudinal design. (T)%The risk of self-selection bias is not a potential problem in an experimental study. (T)%A researcher would choose a nonexperimental approach when ethical constraints prevented manipulation of the independent variable. (T)%The pretest-posttest design collects data from subjects twice. (T)%Answer the following questions true or false.%Size alone can guarantee a good sample. (F)%Sampling issues are handled differently by qualitative and quantitative researchers.(T)%Qualitative researchers employ very different sampling strategies and are guided by different considerations than quantitative researchers. (T)%In qualitative research random sampling is not attempted. (T)%In qualitative research sample size is determined by data adequacy rather than the need to achieve certain statistical goals. (T)%A sample for a quantitative study is good if it is representative. (T)%In quantitative research size, method of selection, response rate and subject attrition would all be factors in determining the quality of a sample. (T)%Many quantitative studies in nursing have weak sampling designs. (T)%Power analysis is used to estimate the sample size needed to adequately test research hypotheses. (T)%The researcher hand-picks people to be included in a study in cluster sampling. (F)%The selection of participants or sampling from a population using random procedures. (probability sampling)
