Quantitative Research Designs Worksheet = 15 points (Experimental, Quasi-experimental, Cohort, Case Control, Systematic Review, Evidence Based Practice Guidelines) NAME: Jayden Kramlich *Each question is worth one point and may have more than one question or part. *Use this worksheet; place answers right under the question*Answers must be type written. *Select the questions, under each section, that you want to answer; See the number of questions to answer in each section. *Use the textbook, power point slides, and Yuja videos to answer the questions. If you use a different source, you will need to reference the source to receive credit. *Highlight the questions that you selected to answer *Bonus available to complete below Experimental, Quasi-experimental, Research Design section (select 8 questions to answer) 1. What are the two types of comparison interventions or control groups that are used in research studies? 2. Explain how inclusion and exclusion criteria decrease or control extraneous variables. 3. Describe a Random Control Trial (RCT). - Random Control Trial is when researchers what to use cause and effect on patients with patient outcomes. It can be considered as the gold standard for evaluating the cause and effect relationship. 4. What is a placebo intervention? What does it do? Give your own example of a placebo intervention, that is not a medication. - A placebo intervention also known as a dummy treatment, is used in a research study to understand the real effects of a new treatment. There are pros and cons to doing this, but overall it allows the researchers to come to a better conclusion regarding the cause and effect. An example of a placebo could be a dummy pill used in a research trial for headaches while another group of people take the actual drug, and some are the used as control groups. 5. Key features of Experimental studies include: Select all that apply: Highlight, bold, or underline your answer/s: a. Adequate sample size b. High level of missing data c. Inconsistent delivery of interventions d. Well defined target population e. Low levels of missing data

6. In Experimental research, an independent variable may be described in several ways. Please provide two other names for the independent variable. - Experiment intervention, treatment group, exposed variable, intervention group and manipulated variable 7. Describe the steps taken in Experimental studies to keep research data collectors and participants from knowing which treatment or intervention group the participants received. 8. An important extraneous variable that is not controlled, eliminated, or taken into account statistically, becomes what type of variable? 9. In Experimental research, what is the most powerful way to place research participants into groups? What will this ensure? - Placing the participants into random groups will always be the best for research. It minimizes the risks of having majorly different groups due to characteristics, biases, and other variables. 10. Why is a “power analysis” done when designing experimental studies? - Power analysis is done when planning research studies so that researchers are aware of finding an effect interest. 11. Why are quasi- experimental studies still valid studies to do, even though they may lack some key features? 12. Give your own example of blinding that may be used in experiments that has not been shared in the textbook or PowerPoint slides. 13. In the Exemplar in Chapter 7, what did the control group receive? What did the experimental group receive? 14. In the Exemplar in Chapter 7, what were the exclusion criteria? 15. In the Exemplar, in Chapter 7, was inter-rater reliability done when providing the intervention and IV insertion? Yes, No, Why? or Why not? Explain. (See the procedure section of the Exemplar) 16. In the Exemplar, in Chapter 7, what instruments were used to collect the data? Be specific. 17. In the Exemplar, in Chapter 7, how can nurses use the findings What education can they provide patients, families, and other nurses?

18. Giving a group of teenagers a survey regarding their caffeine intake would be what type of study design? Highlight, bold, or underline your answer: a. Qualitative study design b. Quantitative study design 19. Quasi-experimental studies may lack what features: Select all that apply: Highlight, bold, or underline your answer/s: a. Convenience sample b. Tight control c. Comparison group d. Random assignment e. Intervention or experiment Cohort, Case Control, Systematic Review Research Design, Evidence-Based Practice Guidelines section (select 7 questions to answer) 1. Do Cohort research studies look forward in time or backwards in time? Please explain your answer. - Cohort studies would be followed forward in time because researchers want to see the cause and effect of a curtain exposure. Participants of the study are followed up on in the future to see what happened as an outcome due to a specific exposure. 2. Describe two concerns or limitations of Cohort research studies. 3. In Cohort studies, data analysis is often completed by what means? 4. Give an example of a cohort that would be interesting to follow. Describe why you would like to follow this cohort. - A cohort that would be interesting to follow would be a small population after a natural disaster. What outcomes they would have health wise. 5. Do Case Control research studies (case studies) look forward in time or backwards in time? Please explain your answer. 6. Why are Case Control research studies (case studies) highly prone to confounding variables? 7. Give an example of a Case control research study (case study) that you would find interesting to complete and why? 8. What outcome variables were studied in the Exemplar in Chapter 8?
