- If possible please answer all four questions. For each hypothesis, identify the independent and dependent variable. Also, decide on an appropriate control group and form of data. Thank you.1) Chi-square analysis generates a p value, an important indicator of statistical support for a hypothetical outcome. If a p value = 0.05 > p > 0.01, the tested hypothesis fails to be falsified. Agree/Disagree? Answer with explanation here: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:
- what is the Expectation and outcome of results, Logical interpretation of the dataand any errors?I'm trying to make sense of what I'm supposed to do I have to write two statements on the conclusion on my pendulum prediction. If your predication was supposed or no and what, you conclude about the variable that was tested? explain possible sources of errors of things that could have been affected your experiment? how you used the scientific method and the last question is to suggest two things that could be done to improve your experiment? can you please explain what these questions mean? I have to put them in statements but not sure what they mean. I'll include what my teacher said. Here is my advice to distinguish between the dependent and independent variables. The dependent variable depends on the independent variable. So, set up two statements comparing your two variables, such as kick distance and leg strength. Does leg strength depend on kick distance? Or does kick distance depend on leg strength? One of those statements will make more sense than the other. It…You compare the 95% confidence intervals associated with two means and note that they do not overlap. What can you conclude? Select one O a. The null hypothesis can be accepted. Ob. There is significant experimental error associated with the data set. Oc. The standard errors are not significantly different. Od. The associated means are significantly different.
- If I set up a Chi square analysis and determine that I cannot reject the null hypothesis based on my data, but the null hypothesis should be rejected, what kind of error is that? a. Type II error b. Type I error c. Conservative errorI believe that the correct answer is: p^2+2pq+q^2=1 I just want to make sure that I am understanding the Hardy-Weinberg Equilibrium correctly.The 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
- “Correlation does not prove causation” means that (a) if two variables are correlated, one is likely to have caused the other. (b) if changes in one variable cause changes in another, the variables are not correlated. (c) only experimental research can answer questions about the natural world. (d) although two variables are interrelated, changes in one do not necessarily cause changes in the other. (e) none of the aboveWhich is the correct equation for the chisquare statistic? Group of answer choices a)x^2 = [(observed-expected)^2]/expected b)x^2 = sum[((observed-expected)^2)/observed] c)x^2 = sum[((observed-expected)^2)/expected] d)x^2 = sum[(observed-expected)/expected] What is a "p-value"? Group of answer choices a)the threshold at which you will reject the null hypothesis b)the probability of the null hypothesis being false c)the percentage of days you are sick during the year d)the probability of the null hypothesis being trueWhat are the hypothesis, positive and negative controls of Griffith's experiment?
