1. 40 OT students were randomized into two groups and 40 nursing students were randomized into two groups. One of the OT groups and one of the nursing groups were given the opportunity to participate in a research project and present their data at an IPE conference. The other group of OT students and nursing students completed their normal course work. At the end of the semester the faculty measured all of their students’ knowledge about research design and confidence presenting information to others. (a) Independent Variable(s): (b) Dependent Variables(s): (c) Research Design: 2. 60 participants with a diagnosis of bulbar type ALS were divided into two groups to work with SLP either 3 times a week for 1 hour or 6 times a week for 2 hours. At the end of the study, all participants completed an assessment of speech quality and swallowing ability. (a) Independent Variable(s): (b) Dependent Variables(s): (c) Research Design:
1. What are the independent and dependent variables in each of the experiments? 2. What information should be added to the diagram to give the reader a better understanding of how these experiments were conducted? 3. What items should have been CONTROLLED in the experiments? 4. How much confidence would you have in the conclusion of experiment 3 if you found out that the temperature was not controlled? Explain your reasoning. 5. Create your own flow chart to answer a causal question.
The confidence interval is reported as follows: Lower 95% CI < p < Upper 95% CI For this question you will be calculating the confidence interval but only reporting the Upper 95% CI using the Agresti-Coull Method. ( (you'll need to know the whole 95% CI for a future question) Do NOT use calculations from previous questions, this is a new scenario. In the Invisible Gorilla Experiment, 24 students were watching the video, only 7 noticed the gorilla. Calculate the 95% CI using the Agresti-Coull method, but only report the Upper 95% CI. Report your answer to 3 decimals.
Why the results of the Swan-neck flask experiment were reliable ?: Select one: a. Because it maintained no controls at all b. Because proper controls were maintained and only one variable changed at a time c. Because many controls were maintained d. Because it was repeatedly done by several scientists e. Because it tested all variables at the same time
I am trying to figure out these four things. What is the independent variable, what is the dependent variable, what are the controlled variables and why this experiment doesn’t use a control.
The scientists are interested in examining other factors that could affect the reaction rate of cellulase. Think about an idea for their next experiment and answer the following questions:
Consider the variables: A, B, C, D, E, F, G, and H. A and B, B and C, C and D are directly related while D and E, E and F, F and G, and G and H are inversely related. If an initial increase occurs in the value of A, the value of H will a. decrease b. increase c. stay the same d. cannot predict from the given information

An experiment was carried out to determine whether drinking caffeinated soda increases pulse rate. The pulse rate of two groups of people at rest were measured. Group A was then given caffeinated soda and group B was given caffeine-free soda. One hour after drinking the soda, the pulse rates were measured. The participants in the experiment were all the same age, and they were all given the same amount of soda. 19 20 21 22 23 *REQUIRED 2 14.

1.________ errors may be avoided by ensuring that the tools that are used in the experiment are properly calibrated. 2. _______ errors can be minimized by conducting many trials
The '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.
