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?
Acne is a common skin disease that affects most adolescents and
can continue into adulthood. A study compared the effectiveness
of three acne treatments and a placebo, all in gel form, applied
twice daily for 12 weeks. The study's 517 teenage volunteers
were randomly assigned to one of the four treatments. Success
was assessed as clear or almost clear skin at the end of the 12
week period. The results of the study can be seen in the table
below. Using the appropriate statistical test, determine if there is
significant evidence that the four treatments perform differently.
If so, how do they compare.
An ANOVA provides the following data:
Group A's mean is 14.38; group B's mean is 11.81; group C's mean is 9.57; HSD is
2.36
What are the significant differences between these conditions?
O Group A has a significantly higher mean than group B and group C; there is no significant
difference between group B's and C's means.
O There are no significant differences among these group means.
O Groups A and B do not significantly differ, but they are both significantly higher than group C.
O Group A has a significantly higher mean than group B and group C; group B has a significantly
higher mean than group C.

- Very large random samples of Catholics, Protestants, and people with no religious affiliation have been questioned about their opinions on capiital punishment. On a ten point scale, the Protestants average 6.9, the Catholics averaged 7.0, and the people with no religious affiliation averaged 7.1. These differences were tested by ANOVA and found to be statistically significant. What is the most reasonable conclusion? a. This is a statistically significant and important difference b. This difference may be statistically significant but it seems unimportant c. This difference is due to random chance d. The researcher should have used sample means rather than proportions in this situationarrow_forwardA poll was conducted to investigate opinions about global warming.
