- What source of variation is found in an ANOVA summary table for a within subjects design that is not in an ANOVA summary table for a between subjects design. What happens to this source of variation in a between-subjects design?What quantitative research design should be used in "Relationship between Academic Stressors and Learning Preferences ofSenior High School Students" and why?6. True or False? A clinical trial is conducted to compare an experimental medication to placebe to reduce the symptoms of asthma. One hundred participants are enrolled in the study and randomized to receive either the experimental medication or placebo. The primary outcome is self-reported reduction of symptoms. Among 50 participants who receive the experimental medication, 30 report a reduction of symptoms as compared to 15 participants of 50 assigned to the placebo. The 95% CI for the relative risk of participants reporting a reduction of symptoms between the experimental and placebo groups is between 0.114 and 0.486.
- . A researcher is using a one-way ANOVA to see whether a significant difference can be found between 3 types of teaching methods in students’ success. How would you phrase the null hypothesis? How would you phrase the alternative hypothesis?he table below summarizes baseline characteristics of patients participating in a clinical trial. a) Are there any statistically significant differences in baseline characteristics between treatments groups? Justify your answer. characteristic placebo(n=25) Experimental(n=125) p Mean 54 +/- 4.5 53+/-4.9 .7856 % female 39% 52% 0.0289 %less than HS education 24% 22% 0.0986 %completing HS 37% 36% %completing some college 39% 42% Mean(Sd SBP 136+/-13.8 134+/-12.4 0.4736 Mean Sd. total cholesterol 214+/-24.9 210+/-23.1 0.8954 %current smokers 17% 15% 0.5741 %…Interpret these results of a Two-Way Anova Analysis with the given info.
- If there is an overall significant F in a one way ANOVA, can we conclude that the group membership or treatment variable caused the observed differences in the group means? Why or Why not?When doing an ANOVA, you observe large differences in means between groups. Within the ANOVA framework, this would most likely be interpreted as evidence strongly favoring which hypothesis?
