What is the simpliest way to explain the following question to me so I can write an essay: Provide two scenarios: one where a Type I error occurs and another where a Type II error occurs. What factors influence the magnitude of risk for each of these and what practices might a researcher engage to minimize these risks? If the null hypothesis is incorrectly reported as significant, which type of error is occurring and what might the subsequent implications be? What conclusions, if any, can be drawn from such results?

- If your question is that your significant hypothesis test is significant “enough” to have true meaning, what are some other things you can look at to determine practical significance?A New York Times article titled For Runners, Soft Ground Can Be Hard on the Body considered two perspectives on whether runners should stick to hard surfaces or soft surfaces following an injury. One position supported running on soft surfaces to relieve joints that were in recovery from injury. The second position supported running on hard surfaces since soft surfaces can be uneven, which may make worse those injuries a soft surface was intended to help. Suppose we are given sufficient funds to run an experiment to study this topic. With no studies to support either position, which of the following hypotheses would be appropriate? 1. The second position makes the more sense, so this should be a one-sided test. In this case, we should form the alternative hypothesis around the first position. 2. Because we would be interested in any difference between running on hard and soft surfaces, we should use a two-sided hypothesis test. 3. Because there is uncertainty, we should postpone…Just because a statistically significant result occurs doesn’t mean we should quickly alter our lives to align with the result. Think about this last one? Can you think of a study where you would rather NOT reject the null hypothesis? Give me a brief synopsis of a study where you would WANT to reject the alternative hypothesis (or retain the null) and give me your anticipated hypothesis as a Problem.
- The researchers hypothesized that people who view intelligence as highly stable will be more likely to overestimate their performance than those who view intelliegence as changeable. When testing that hypothesis, what is the outcome variable? a. The participants' scores on the antoymns test b. The participants' on the measure of their theories of intelligence c. The participants' estimates of their test performance relative to other test takers d. The participants' predictions of their scores on the antoymns testA previous researcher has published a report demonstrating that students’ interest in studying mathematics is related to his or her interest in general academics. Furthermore, this researcher also claimed that interest in studying English-related subjects (literature, journalism, etc.) was not related to interest in mathematics. However, after reading the article, you believe the findings contradict your experience, and you believe there was a methodological flaw in the analysis. In particular, you believe it was necessary for the researcher to have accounted for another variable: gender. Your plan is to collect a small data set from 2 groups of students. Your research questions are based around the hypothesis that the relationship between interest in mathematics and interest in both academics & English subjects is moderated by gender. Using the same measurement scales for interest as the first researcher, you collect data from two groups. The first group is all…Given the following 3 problems/situations, complete the hypothesis testing process: A. State the research hypothesis B. State the null hypothesis C. Choose a level of statistical significance (alpha level) D. State the decision rule. E. Select and compute the test statistic (Use the given) F. Make a decision regarding whether to accept or reject the null hypothesis. G. Interpret results by concluding and making implications Problems/situations 1. A researcher wants to determine whether there is an association between weight and scores on the self-esteem scale. Е. R-value: .213 P-value = .34
- For each of the following three studies Identify whether the hypothesis can be tested experimentally or if it is a non-experimental hypothesis. What is the independent variable/grouping variable (and which is it, IV or GV)? What is the dependent variable? Identify the null hypothesis, both in your own words and by writing the statistical hypothesis using the population parameter notation discussed in class. What is the non-directional alternate hypothesis? Write it both in your own words and the statistical parameter notation discussed in class. (Make sure these both specify the same direction.) Make your best guess about a directional alternative hypothesis – that is, what you would expect to happen in this study. Write it in your own words and using the statistical parameter notation discussed in class. ***Be sure you use the correct label (H0 or H1/Ha) for your statistical hypotheses.
