Question 3>Which of the following statements is false about the principles of a good experiment?O Studying many cases (e.g. including many patients in a study) is often more helpful than justincluding a few cases in the study.O Using a control group with a placebo is important since otherwise subjects in the controlgroup may behave differently than these in the treatment group.O If we collect more information on each case (e.g. take repeated measurements on eachindividual) that might be helpful to obtaining more precise results in an experiment.OWe can always generalize the result of a study to the greater population so long as werandomize which patients go into which study groups.Randomizing individuals into groups is one way of preventing accidental bias from creepinginto a study.Considering (controlling) more variables in planning an experiment helps ensure each studygroup is similar to the other study groups.> Next Questionétv18&%%248.9.674.

A scientist wants to examine factors that may be related to cancer. The scientist believes that differences in age at death that will be found when determining what type of smoker a person was (pipe smoker, cigar smoker, cigarette smoker, or nonsmoker) but he also thinks it is important to consider the extent of smog in the person’s environment. For this new extended study, the people in the sample are divided up into those who lived in areas with heavy smog and those who lived in areas that were relatively free from smog. Smoking habit remains the other independent variable, and the dependent variable remains age at death. The new question of major interest to the scientist is whether the pattern of differences in age at death attributed to smoking habits would be influenced by whether people lived in smog-filled environments. What is the appropriate statistic? a. Dependent groups t-test b. Phi Coefficient c. Point Biserial r d. t-test for r > 0…
Suppose we wish to compare the health status of two groups of people. What variables might we use to measure the status? What variables might we want to control in order to draw the appropriate inferences and why?
Tourism is extremely important to the economy of Florida. Hotel occupancy is an often-reported measure of visitor volume and visitor activity (Orlando Sentinel, May 19, 2018). Hotel occupancy data for February in two consecutive years are as follows. Current Year 1,476 1,800 Occupied Rooms Total Rooms 1,422 1,800 a. Formulate the hypothesis test that can be used to determine whether there has been an increase in the proportion of rooms occupied over the one-year period. Let P₁= population proportion of rooms occupied for current year P2 population proportion of rooms occupied for previous year - P2 less than or equal to 0 greater than 0 Ho P1 Ha P1 P2 b. What is the estimated proportion of hotel rooms occupied each year (to 2 decimals)? Current year .80 X Previous Year .77 c. Conduct a hypothesis test. What is the p-value (to 4 decimals)? Use Table 1 from Appendix B. Previous Year p-value = 0.0166 Using a 0.05 level of significance, what is your conclusion? We can conclude that there…
A study designed to compare two ethnic groups on a measure of a particular personality trait used a large number of participants to have high power. The study found a significant result, but the difference between the means was very small (that is, there was a small effect size). Talk about the fact that this test is statistically significant but may not be practically significant?
A teaching assistant for a psychology course is curious about what factors are associated with higher final grades in the course. She finds that students who read the textbook tend to have higher final grades in the course. She finds that students who watch the lecture videos tend to have higher final grades in the course. Lastly, she finds that students who read the textbook and watch the lecture videos tend to have the highest grades in the course. Assuming that any difference is statistically significant, which of the following best characterizes these results? 1 main effect and O interaction effects 1 main effect and 1 interaction effect O main effects and O interaction effects 2 main effects and 1 interaction effect O main effects and 1 interaction effect 2 main effects and O interaction effects
I UNDERSTAND 2,3,4 BUT I DON'T GET NUMBER 1 QUESTION? Thread prompt: An epidemiologist found five cases of “big toe cancer” in the Yukon Territory. Because there were only a few cases, the epidemiologist decided to conduct a matched case-control study to determine whether shoe size larger than 9 is a risk factor for big toe cancer. Cases were individually matched to one control for daily activity, history of athlete’s foot, and history of ingrown toenails. The following data were gathered: Shoe size > 9 Pair Case Control 1 Yes No 2 No No 3 No Yes 4 Yes Yes 5 No Yes Compute the proper measure of association. Interpret your results. If you were to investigate a rare cancer in Lynchburg, where might you look for data? What would be necessary legally and ethically to be able to utilize this data set(s)?
Researchers asked soda drinkers to view either the logo for their favorite soda or a graphic warning demonstrating the harmful effects of sugary beverages (e.g., tooth decay, obesity) and then measured their negative mood with a short survey. They found that those participants who saw the warnings reported significantly greater negative moods than those who saw the logos. Which statistical test should be used?
What conclusions can be drawn from a study with a “statistical significance” result? What information do you look at to evaluate whether an effect obtained in an experiment is large enough to have a “practical” or “clinical” significance?
(OPHTHALMOLOGY) The following data are from a study on Botox injections. Patients received a high-dose injection in one eye (experimental treatment = treatment E) and a low-dose injection in the other eye (control treatment = treatment C). Patients were asked to rate the level of pain in each eye on a 1–10 scale, with higher scores indicating more pain. The assignment of treatments to eyes was randomized. The subjects came back over several visits. Data from the last visit are given in the following table: 1. Which of the following is the correct test to conduct given the situation above? 2. The hypotheses are: 3. What is the level of significance? 4. What is the computed test statistic? Hint: Use (mean of "Pain in E eye") minus (mean of "Pain in C eye") 5. What is the correct decision based on the p-value or critical value method?

One disadvantage of a repeated measures design is the possibility of order effects. Which of the following statements is false? O Order effects are often due to the treatment itself. O Order effects can bias the results of an experiment. O Order effects can be lessened by applying counterbalancing to the experimental design. O An order effect is an increase or decrease in the response to each subsequent treatment due to an increase in learning, fatigue, or boredom.
