What type of hypotheses is this? There is a relationship between social distance in families and burden of caregiving for chronically ill adults.(correlational or causal?)

This hypothesis is a null hypothesis because the researcher is stating there is no relationship between the variables.

What type of hypotheses is this? There is a positive relationship between nurse attitudes toward AIDS patients and number of AIDS patients for whom they have cared.(directional or non directional?)

This hypothesis is an example of a directional hypothesis because the researcher is looking for a positive outcome or relationship between the variables.

What type of hypotheses is this? Rates of use of health care facilities by ethnic minorities are higher in facilities with bilingual health care staff.(simple or complex?)

This hypothesis is an example of a simple hypothesis because the researcher is examining the rates and not seeking a relationship.

The feasibility of conducting a study is determined by examining which of the following? A) Availability of subjects B) Previous studies C) Researcher's credibility D) Significance of research problem

ANS: A A. The feasibility of a research problem and purpose is determined by examining the researcher's expertise; money commitment; availability of subjects, facilities, and equipment; and the study's ethical considerations. B. Previous studies may help guide a researcher to conduct a certain study, but do not determine its feasibility. The feasibility of a research problem and purpose is determined by examining the researcher's expertise; money commitment; availability of subjects, facilities, and equipment; and the study's ethical considerations. C. The researcher's credibility may impact a grant award or the interpretation of the study, but not whether it can be carried out. The feasibility of a research problem and purpose is determined by examining the researcher's expertise; money commitment; availability of subjects, facilities, and equipment; and the study's ethical considerations. D. The significance of the research problem relates to whether or not it is seen as important. The feasibility of a research problem and purpose is determined by examining the researcher's expertise; money commitment; availability of subjects, facilities, and equipment; and the study's ethical considerations.

The purpose of control in a study design is to: A) Establish the credibility of the researcher. B) Highlight design flaws. C) Increase the probability that the results are true to reality. D) Interfere with the validity of the findings.

ANS: C Feedback: As control increases, the likelihood that the study findings are an accurate reflection of reality increases.

Which of the following is not a requirement for an experimental study? A) Random sampling B) Control group C) Repeated measures D) Control of the intervention

ANS: C Feedback: Repeated measures is not a requirement for an experimental study.

The initial and one of the most significant steps in conducting the research process is: A) Defining the research variables. B) Determining the feasibility of the study. C) Identifying the research problem. D) Stating the research purpose.

ANS: C The problem provides the basis for developing the research purpose. Variables are defined once the study problem and purpose are clearly identified. The problem provides the basis for developing the research purpose. The feasibility of a study is an important consideration once the problem and purpose have been established. The problem provides the basis for developing the research purpose. The research purpose is a clear, concise statement regarding the goal of the study; it comes from the need identified through the research problem. The problem provides the basis for developing the research purpose.

The research purpose should identify the study variable(s) and what other key aspect of the study? A) Design B) Measurement tools C) Population D) Statistics

ANS: C The purpose includes the variables, population, and often the setting for the study. The study design is how the research is going to be carried out. The purpose includes the variables, population, and often the setting for the study. Measurement tools that are used are included in the methodology section. The purpose includes the variables, population, and often the setting for the study. Statistics are included as part of the methodology. The purpose includes the variables, population, and often the setting for the study.

In evaluating a correlational design as sound, one would look for all but which of the following? A) Large sample B) Low response rate of subjects C) Sample representing all elements of the population D) Wide range of scores on measurements

Answer: A
