- I am stuck on four questions for this lab and they are: 1. What is the question being investigated in this experiment. 2. What is the independent variable? 3. What is the dependent variable? 17. What are the control treatments?Which of the following statements BEST describes the concept of contamination in a randomized control trial? Question 6 options: The intervention group is exposed to treatments received by the control group The intervention group receives an intervention other than the intervention being implemented The control group is exposed to the treatment received by the intervention group The control group receives an intervention other than the intervention being implementedThe α level in the context of reporting findings from a randomized controlled trial corresponds to the probability of concluding: Correctly that the treatment and control groups differ with respect to risk of outcome. That the treatment and control groups differ with respect to outcome when in fact they do not. Correctly that the treatment and control groups do not differ with respect to outcome. That the treatment and control groups do not differ with respect to outcome when in fact they do. That you don’t have sufficient information to present results.
- what is the Expectation and outcome of results, Logical interpretation of the dataand any errors?What are the shortcomings of randomized clinical trialsThe '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.
- What preliminary conclusions can you draw from the results of the experiment and what is the independent and dependent variable ?The variable is a part of the experiment that varies or changes. True FalseThe null hypothesis is: That the measured value is zero That the proposed model is not correct and the measured factors have no effect on the pattern That the proposed model is correct and perfectly explains the pattern That the experiment is null and void
- A properly designed experiment contains the following: positive and negative controls and experimental conditions. positive control and experimental conditions. positive and negative controls control and experimentalan independent variable is the variable measured in an experiment. True or FalseIn an experiment, the control group is used to: a Change the variable b Provide a baseline for comparison with the test group c add additional non-dependent variables d demonstrate correlation rather than causation e generate hypotheses
