Assignment 2: Identifying Research Study Designs

Instructions

A research design is sometimes referred to as the blueprint for a study. Four types of quantitative designs discussed in your text are descriptive, correlatio 11:59pm.

Attempt Historynal (nonexperimental), experimental, and quasi- experimental. This activity will help you identify the different designs.

Review Chapters 2, Table 2-3, 3, 10, 11.

Question 1

Sarah plans to conduct a study about the relative amounts of stress in individuals. She wanted to know the amount of stress among adolescents, young adult, middle adult and the late adult women. The research design of her study would be:

Cohort

descriptive

Qualitative

correlational

Rationale: Correlational design is used to examine relationships

among variables. Unit Two, p. 207

Question 2

Jane wanted to know the relationship between the level of anxiety experienced during final exams and the exam performance among the level 4 student nurses. The type of research design utilized is:

quasi-experimental

retrospective

correlational

experimental

Question 3

Amy randomly groups research participants into two groups and tests the effects of yoga on stress levels. This study uses this type of research design:

correlational

experimental

comparative

Rationale: Experimental designs are used to determine evidence

of causation Unit Two, p. 231

Question 4

Association is the same as causality.

False

True

Question 5

This is another type of quantitative research design wherein the researcher wanted to know about the cause and effect relationship between variables, where the cause is being manipulated and respondents are chosen by choice not by chance.

true experimental

descriptive

correlational

quasi-experimental

Rationale: quasi-experimental designs are “like” experimental designs but lack one of the three criteria, In this example, the random assignment of participants in missing. Unit Two, p. 238

Question 6

Bob wanted to conduct research that will delve into knowing the strength of the relationship between post-traumatic stress disorder and the academic performance of nursing students during the final year of nursing school. The type of research design most suited towards his study would be:

descriptive

correlational

causal-comparative

experimental

Question 7

Fran conducts a study that will characterize the frequency of staff resignations between the north and south affiliated hospitals within a hospital system. What’s the type of research design to be used in her study?

experimental

causal-comparative

descriptive

correlational

Rationale: Rationale: descriptive design is used in order to measure the incidence or prevalence of a phenomenon of interest. Unit Two, p. 200

Question 8

Members of the health team introduce a new admission system and wish to study the efficiency of its implementation as compared to the previous admission system which is still being practiced in other departments. In this study, it is not feasible to conduct randomization. What type of research design is used?

quasi-experimental

predictive - correlational

experimental

retrospective

Rationale: quasi-experimental designs are “like” experimental designs but lack one of the three criteria, In this example, the random assignment of participants in missing. Unit Two, p. 238

Question 9

A quantitative research paper is entitled as “Nursing Model of Care Utilized by Selected Hospitals and its Association with the Performance of Nurses in their Area of Assignment”. What is the research design of this study?

Descriptive

Survey

Experimental

Correlational

Rationale: Correlational design is used to examine relationships or associations among variables. Unit Two, p. 207

Question 10

The dependent variable is the experimental treatment.

True

False

The independent variable is the experimental treatment.
