The impact of the inclusion of a school transport on the punctuality levels of the students is studied D. A particular orthopedic surgeon has the highest success rate for performing knee surgeries. A lot of other hospitals or doctors have taken up this case to understand and benchmark the method in which this surgeon does the procedure to increase their success rate. E. A study interested in why certain groups of trees are dying, while others of the same type and in the same location are thriving, can observe the trees and their surrounding environment to come to a preliminary decision.The following are reasons why randomized control trials (RCTs) are not used to investigate all research questions, except: a. RCTs can be expensive, which can make it difficult if funding is limited b. RCTs can be time-consuming, and it may take months and sometimes years to obtain final results c. For certain research questions and/or certain types of exposure variables, it may not be ethical to conduct an RCT d.

- Which of the following are drivers of evidence-based practice (EBP)? Select all that apply. a. Knowledge and skills in evidence-based practice b. A supportive culture c. Access to computers and databases d. Availability of EBP mentors e. One of the many factors required for ANA credentialing for Magnet recognitionA research study is said to be double-blind if A. a change that reflects the participants’ expectations is observed B. the subject knows that he/she is receiving two treatments during the experiment C. neither the subjects nor the investigators know which study group is receiving the placebo D. the placebo has two possible effects on the study groupThe 'control group' is an essential component of an experiment. This is because 1. A control group allows one to determine if a particular result is due to the experimental variable. 2. No, it's not essential in experimentation. A control group is not always necessary it depends on the experiment. 3. A control group allows for multiple variables to be tested at the same time. 4. A control group is required for the development of a prediction.
