Explain the concept of randomized controlled trials, and Assess the usefulness of randomized controlled trials in measuring program impact.
a) Randomized controlled trials.This is a type of scientific experiments in which the aim is to reduce the sources of bias when testing the effectiveness of new treatments. this is done by random allocation of subjects to two or more groups in which treatment is given differently& then compared with respect to a measured response.
b) the RCT must be generally planned from tine very beginning of the program & its participation must be cautiously watched keeping the experiment in mind. generally they are useful for programs that has a clear& measurable impacts that can be attributed to distinct set of interventions.for example we can take the reform program in an organization where the policies for worker pay can be developed through a RCT where there is different incentive packages within the workers.

The Abecedarian Project is a randomized controlled study to assess the effects of intensive early childhood education on children who were at high risk based on several sociodemographic indicators. The project randomly assigned some children to a treatment group that was provided with early educational activities before kindergarten and the remainder to a control group. A recent follow-up study interviewed subjects at age 30 and evaluated educational, economic, and socioemotional outcomes to learn if the positive effects of the program...
Explain the differences between a research article (Randomized Controlled Trial) and a systematic review (SR) article. How can you tell them apart by quickly looking at them?
7. Ethical standards for randomized, controlled clinical trials include never testing drugs which have not been proven to be completely safe. not asking subjects to agree to participate without first informing them of the nature of the study and possible risks and benefits. ensuring that each subject knows which treatment he or she received. allowing subjects to decide whether or not to be in the control group. all of these. 8. Which of the following is not a requirement for...
Help me answer this Explain the usefulness of the Security Market Line in assessing common stock risk. Explain how we use bond rating categories to assess bond risk
. An investigator wants to assess the usefulness of a certain symptom (S) in the diagnosis of a particular disease (D). In a random sample of 800 patients with the disease, 774 reported having the symptom. In an independent random sample of 1280 subjects without the disease, 17 reported having the symptom. a. Explain what a false positive would be in this situation. b. Explain what a false negative would be in this situation. c. What is the sensitivity of...
In a randomized, controlled trial, there was found to be statistically significant evidence of a reduction in myocardial infarction (heart attack) risk in participants who took aspirin. Participants who took aspirin had a 44% reduction in risk of heart attack as compared to their counterparts who received placebo (relative risk = 0.56; 95% confidence interval, 0.45 to 0.70). If you conducted a hypothesis test on the data, do you expect the p-value to be less than 0.05 or greater than...
Researchers conduct a randomized controlled trial to determine if a regular resistance exercise program improves post-operative function in knee surgery patients compared to patients who undergo an aerobic exercise program. The primary purpose of randomizing patients to each of the interventions in this trial is to avoid? a. recall bias b. selection bias c. surveillance bias d. non-random (differential) misclassification of exposure status e. non-random (differential) misclassification of outcome status
